BACKGROUND

Hematopoietic stem cells (HSCs) are clonogenic cells, which possess the properties of both self-renewal (expansion) and multilineage potential giving rise to all types of mature blood cells. HSCs are responsible for hematopoiesis and undergo proliferation and differentiation to produce mature blood cells of various lineages while still maintaining their capacity for self-renewal. The ability to self-renew maintains the HSC population for the lifespan of an animal and also allows HSCs to repopulate the bone marrow of lethally irradiated congenic hosts.


Early HSC development displays a hierarchical arrangement, starting from long-term (LT-) HSCs, which have extensive self-renewal capability, followed by the expansion state, which corresponds to short-term (ST-) HSCs (having limited self-renewal ability) and proliferative multipotent progenitors (MPPs) (having multipotent potential but no self-renewal capability). MPP is also a stage of priming or preparation for differentiation. An MPP differentiates and commits to become either a common lymphoid progenitor (CLP), which gives rise to all the lymphoid lineages, or a common myeloid progenitor (CMP), which produces all the myeloid lineages. During this process, the more primitive population gives rise to a less primitive population of cells, which is unable to give rise to a more primitive population of cells. The intrinsic genetic programs that control these processes including the multipotential, self-renewal, and activation (or transient amplification) of HSCs, and lineage commitment from MPP to CLP or CMP, remain largely unknown.


To sustain constant generation of blood cells for the lifetime of an individual, HSCs located in bone marrow niches (Zhang, J. et al. Nature 425, 836-841, 2003; Calvi, L. M. et al. Nature 425, 841-846, 2003; Kiel, M. J., et al. Cell 121, 1109-1121, 2005; Arai, F. et al. Cell 118, 149-161, 2004) must achieve a balance between quiescence and activation so that immediate demands for hematopoiesis are fulfilled, while long-term stem cell maintenance is also assured. In adults, homeostasis between the quiescent and activated states of stem cells is important to protect HSCs from losing their potential for self-renewal and, at the same time, support ongoing tissue regeneration (Li, L. and Xie, T. Annu. Rev. Cell. Dev. Biol. 21, 605-631, 2005). Over-activation and expansion of stem cells risks both eventual depletion of the stem cell population and a predisposition to tumorigenesis. Although some factors important for stem cell activation have been identified (Heissig, B. et al. Cell 109, 625-637, 2002), the molecular events governing the transition between quiescence and activation are poorly understood.


HSCs are responsible for life-long hematopoiesis under homeostatic and stress conditions, which relies on an exquisite balance between stem cell self-renewal and differentiation (Li et al. Science, 327: 542-545, 2010; Weissman et al. Cell, 100: 157-168, 2000). Thus, HSC transplantation is a life-saving therapy for a broad spectrum of disorders, including hematologic, immune, and genetic diseases, as well as cancers (Walasek et al. Annals of the New York Academy of Sciences 1266: 138-150, 2012). However, HSC-based treatment can be limited primarily by the lack of HLA-matched donor bone marrow (BM). Allogeneic transplantation offers an alternative approach, but graft vs host disease (GvHD) remains a life-time challenge, since taking immune suppression medicine has numerous side effects, such as delayed immunological recovery, thrombotic microangiopathy (Sung et al. Stem Cells Translational Medicine, 2: 25-32 (2013); Shlomchik et al. Nature Reviews. Immunology, 7: 340-352, 2007). Transplantation of HSCs from hUCB reduces the risk of GvHD; however, the lower number of HSCs in hUCB than in BM or mobilized peripheral blood limits its application (Walasek et al. Annals of the New York Academy of Sciences, 1266: 138-150, 2012). Targeting single molecules or pathways has been studied for hUCB HSC expansion (Huang et al. Leukemia, 30: 144-153, 2016; Boitano et al. Science, 329: 1345-1348, 2010; Fares et al. Science, 345; 1509-1512, 2014; Ansellem et al. Nature Medicine, 9: 1423-1427, 2003; Antonchuk et al. Cell, 109: 39-45, 2002; Rentas et al. Nature, 532: 508-511, 2016; Himburg et al. Nature Medicine, 16: 475-482, 2010; North et al. Nature, 447: 1007-1011, 2007; Guo et al. Nature Medicine, 2018); Varnum-Finney et al. Nature Medicine, 6: 1278-1281, 2000; and Chou et al. Experimental Hematology, 41: 479-490 e474, 2013). However, other approaches are sought in order to relatively favor stem cell self-renewal versus differentiation (Zhao et al. Molecular Cell Biology, 18: 31-42, 2017).


m6A is a prevalent internal modification in mRNAs that regulates the outcome of gene expression by modulating RNA processing, localization, translation, and eventual decay, which is modulated by “writers,” “erasers” and “readers” of the mark (Roundtree et al. Cell, 169: 1187-1200, 2017; Li et al. Annual Review of Genomics and Human Genetics, 15: 127-150, 2014). Recent studies have elucidated the roles of m6A modification in stem cell fate determination and endothelial-to-hematopoietic transition during embryogenesis (Batista et al. Cell Stem Cell, 15: 707-719, 2014; Geula et al. Science, 347: 1002-1006, 2015; Yoon et al. Cell, 2017; Zhang et al. Nature, 549: 273-276, 2017; Zhao et al. Nature, 542: 475-478, 2017) as well as in leukemia development (Li et al. Cancer Cell, 31: 127-141, 2017; Vu et al. Nature Medicine, 2017; Barbieri et al. Nature, 2017; Weng et al. Cell Stem Cell, 22: 191-205 e199, 2018). Interestingly, deficiency in m6A writer complex, Mettl3 and Mettl14, leads to distinct outcomes in different types of stem cells. For example, Mettl3 or Mettl14 KO promoted differentiation in HSCs (Vu et al. Nature Medicine, 2017; Weng et al. Cell Stem Cell, 22: 191-205 e199, 2018; Barbieri et al. Nature, 2017) while resulting in enhanced stem cell self-renewal and maintenance in mouse embryonic stem cells (mESCs) and embryonic neuronal stem cells (NSCs) (Batista et al. Cell Stem Cell, 15: 707-719, 2014; Yoon et al. Cell, 2017). Besides, the physiological function of m6A in stem cells and leukemia are mediated through different mechanisms. In stem cells, m6A modifications regulate stem cell fate determination by m6A-mediated decay of mRNAs encoding stem cell fate determinant (Batista et al. Cell Stem Cell, 15: 707-719, 2014; Yoon et al. Cell, 2017) while in acute myeloid leukemia (AML), Mettl3 and Mettl14 promote leukemogenesis as m6A modifications stabilize the mRNAs of oncogenes and/or increase their translation (Vu et al. Nature Medicine, 2017; Barbieri et al. Nature, 2017; Weng et al. Cell Stem Cell, 22: 191-205 e199, 2018). Furthermore, previous studies have reported that the leukemogenic functions of FTO and Mettl14 are independent of YTHDF reader proteins (Li et al. Cancer Cell, 31: 127-141, 2017; Weng et al. Cell Stem Cell, 22: 191-205 e199, 2018).


As the m6A RNA modification is modulated by “writers,” “erasers” and “readers” of the mark (Wang et al. Nature, 505(7481): 117-120, 2014), processes that install, recognize and remove this and other marks may have various implications for cellular, developmental, and disease processes. For example, studies have shown that the m6A mark may act as a key post-transcriptional modification to promote initiation of microRNA (miRNA) biogenesis (Alarcon et al. Nature, 519(7544): 482-485, 2015). Evidence also points to m6A RNA modifications possibly being involved in the differentiation of stem cells to specific lineages (Batista, Cell stem Cell, 15(6): 707-719, 2014; Zhang et al. Nature, 549(7671): 273-276, 2017), and in regulating gene expression (Dominissini et al., Nature 485(7397):201-206, 2012; Haussmann et al, Nature 540(7632): 301-304, 2016). A m6A transferase METTL3 has been identified as a regulator for terminating murine naïve pluripotency (Geula et al. Science, 347(6225): 1002-1006, 2015). The m6A “writer” protein METTL3 has also been demonstrated in mouse T cells to disrupt T cell homeostasis and differentiation (Li et al. Nature, 548(7667): 338-342, 2017), and m6A RNA methylation has been found to promote XIST-mediated transcriptional repression (Patil et al. Nature, 537(7620): 369-373, 2016). M6A RNA modifications have also been shown to regulate the ultraviolet-induced DNA damage response (Xiang et al. Nature, 543(7646): 573-576, 2017). Study of the maternal-to-zygotic transition (MZT) as in zebrafish also indicated a role for m6A mRNA methylation in transcriptome switching and animal development (Zhao et al. Nature, 542(7642): 475-478, 2017). Accordingly, while accumulative evidence has brought insights into the biological functions of m6A (Lence et al. Nature, 540 (7632); 242-247, 2016), the function of m6A in adult stems cells are largely unknown.


Hematopoietic stem cells (HSCs) in bone marrow (BM) maintain homeostasis hematopoiesis throughout life and also support regeneration after myeloablation (Weissman, 2000). Quiescent HSCs perform superiorly to proliferative HSCs in lethally irradiated mice, which largely attributes to the quiescent state that protects HSCs from DNA damage (Arai et al., 2004; Fleming et al., 1993; Wilson et al., 2008) (Walter et al., 2015). However, a recent study showed that DNA damage accumulation in HSCs was associated with broad attenuation of DNA repair and response pathways that were dependent upon HSC quiescence (Beerman et al., 2014). In fact, the majority of HSCs, despite their quiescence, are sensitive to DNA damage from chemotherapeutic drugs, such as 5-Fluorouracil (5FU) (Lerner and Harrison, 1990). The unresolved issue is how the hematopoietic system overcomes the consequence of myeloablation. In respect to the remarkable heterogeneity of HSCs during development and in adult (Benveniste et al., 2010; Benz et al., 2012; Fleming et al., 1993; Morita et al., 2010; Zhou et al., 2016), the existence of a reserve HSC (rHSC) subpopulation was proposed, with the features of drug-resistance and capacity to regenerate the bulk of HSCs to overcome stress-caused myeloablation (Haug et al., 2008; Li and Clevers, 2010; Wilson et al., 2008). Thus far, however, no functional evidence has been provided in supporting existence of rHSCs in the blood system.


HSCs are preserved in complex BM niches for their maintenance and regeneration (Li and Clevers, 2010; Mendelson and Frenette, 2014; Morrison and Scadden, 2014; Scadden, 2014; Schofield, 1978). In the past decades, multiple studies have uncovered the complexity of HSC bone marrow niche components, including: endosteal (inner bone surface) cells (Calvi et al., 2003; Zhang et al., 2003), sinusoidal endothelial cells (Hooper et al., 2009; Kiel et al., 2005), Cxcl12 abundant reticular (CAR) cells (Sugiyama et al., 2006), Nestin+ and NG2+ perivascular cells (Kunisaki et al., 2013; Mendez-Ferrer et al., 2010), LepR+ and Prx-1+ mesenchymal stem and progenitor cells (Ding and Morrison, 2013; Ding et al., 2012; Greenbaum et al., 2013), non-myelinating Schwann cells (Yamazaki et al., 2011), and megakaryocytes (Bruns et al., 2014; Zhao et al., 2014). However, whether and how the BM niche complexity contributes to HSC heterogeneity regulation remain largely unclear (Itkin et al., 2016). Furthermore, the first HSC niche was initially identified as the spindle shaped N-Cadherin+ (N-cad+) pre-osteoblastic cells in the endosteum of the trabecular bone region (Calvi et al., 2003; Xie et al., 2009; Zhang et al., 2003), but the nature and function of N-cad+ niche cells in BM remain unclear.


Accordingly, there remains a need for elucidation and understanding of the role of m6A and m6A mRNA pathways to provide insight into molecular regulation of stem cell proliferation and differentiation. There remains a further need for methods of expanding populations of stem cells, both in vivo and ex vivo, and methods of providing treatment with such expanded stem cell populations, such as via transplant into a suitable subject.

DETAILED DESCRIPTION OF THE INVENTION

One embodiment of the invention is a method for expanding a population of stem cells obtained from a tissue selected from the group consisting of peripheral blood, cord blood, and bone marrow. This method comprises modulating a N6-methyladenosine (m6A) mRNA modification pathway in the population of stem cells to expand the number of stem cells.


Another embodiment of the invention is a method for expanding a population of chimeric antigen receptor (CAR) T-cells cells obtained by modifying T-cells obtained from a tissue selected from the group consisting of peripheral blood, cord blood, and bone marrow. This method comprises modulating a N6-methyladenosine (m6A) mRNA modification pathway in the population of CAR T-cells to expand the number of stem cells.


In the present invention the population of stem cells and/or T-cells may be obtained from any mammal, such as, e.g., a human, and from any tissue that contains stem cells and/or progenitor cells and/or T-cells. As noted above, in a preferred embodiment the tissue may be peripheral blood, cord blood or bone marrow.


As used herein, “expand”, “expanding” and like terms means to increase the number of stem cells and/or CAR-T cells in the population relative to the number of stem cells and/or CAR T-cells in the original population either in vivo or ex vivo using any of the methods disclosed herein. The expansion may be at least 40-fold compared to the original number of stem cells and/or CAR T-cells in the population. More preferably, the expansion is at least 2-fold, 4-fold, 5-fold, 8-fold, 10-fold, 15-fold, 20-fold or more compared to the original number of stem cells.


In the present invention “a population of stem cells” means a group of substantially undifferentiated cells that possess the ability to give rise to many different types of cells and which have the ability to self-renew. Representative, non-limiting examples of stem cells according to the present invention include bronchioalveolar stem cells (BASCs), bulge epithelial stem cells (bESCs), corneal epithelial stem cells (CESCs), cardiac stem cells (CSCs), epidermal neural crest stem cells (eNCSCs), embryonic stem cells (ESCs), endothelial progenitor cells (EPCs), hepatic oval cells (HOCs), hematopoetic stem cells (HSCs), hematopoietic stem and progenitor cells (HSPCs), keratinocyte stem cells (KSCs), mesenchymal stem cells (MSCs), neuronal stem cells (NSCs), pancreatic stem cells (PSCs), retinal stem cells (RSCs), and skin-derived precursors (SKPs).


Hematopoietic stem cells, for example, have the ability to self-renew (i.e., expand) and can give rise to all the types of progenitor cells (such as, e.g., CMP, GMP, MEP and CLP) and ultimately all the types of blood cells (such as e.g., red blood cells, B lymphocytes, T lymphocytes, natural killer cells, neutrophils, basophils, eosinophils, monocytes, macrophages, and platelets) in the hematopoietic system. Mesenchymal stem cells, as another example, are multipotent stromal cells that can differentiate into a variety of cell types (such as, e.g., osteoblasts, chondrocytes, myocytes and adipocytes).


In the present invention “a population of chimeric antigen receptor (CAR) T-cells” means a group of T-cells that have been modified with chimeric antigen receptors capable of binding specific antigens, such as antigens on the surface of cancer cells, and may possess the ability to target and kill such cancer cells. The CAR T-cells can be prepared by modifying T-cells with the chimeric antigen receptors, such as by introducing DNA coding for the chimeric antigen receptors into the T-cells, to express the chimeric antigen receptors on the surface of the T-cells (Davila et al. Sci Transl Med 6(224), 224ra25 (2014); Tasian et al. Ther Adv Hematol 6(5), 228-241 (2015).


In the present invention, “modulating”, “modulation” and like terms mean altering the signal transduction pathway, e.g., a protein in the m6A mRNA modification pathway, including but not limited to lowering or increasing the expression level of a protein, altering the sequence of such a protein (by mutation, pre-translational or post-translational modification or otherwise), or inhibiting or activating such a protein (whether by binding, phosphorylation, glycosylation, translocation or otherwise). Such modulation may be achieved genetically or pharmacologically.


In one aspect of the present invention, modulating the m6A mRNA modification pathway comprises introducing a mutation into a population of stem cells and/or CAR-T cells, which mutation results in modulation of a molecule in the m6A mRNA modification pathway. In another aspect present invention, modulation of the m6A mRNA modification pathway also includes contacting the stem cells and/or CAR T-cells with a modulator of a molecule in the m6A mRNA pathway. Representative, non-limiting examples of such modulators include a small molecule, a biologic, an antisense RNA, a small interfering RNA (siRNA), and combinations thereof.


In the present invention, the phrase “modulation of a molecule in the m6A mRNA modification pathway” means altering the function of a member of the m6A mRNA modification pathway, which altered function may have an effect similar to inhibiting or decreasing the function of a molecule involved in a process upstream and/or downstream of m6A modification of mRNA. Non-limiting examples of such “modulation” include increasing or decreasing the expression or function of proteins involved in any of: the incorporation of N6-methyladenosine modifications in mRNA, removal of N6-methyladenosine mRNA modifications to mRNA, and/or the recognizing and processing of N6-methyladenosine modified mRNA. For example, the modulation may include increasing or decreasing N6-methyladenosine modifications in mRNA, and/or affecting the type and/or distributions of such modifications in mRNA, such as by modulating the activity of one or more of a m6A writer (e.g. methyltransferase) and m6A eraser (e.g. demethylase). As another example, the modulation may increase or decreases expression or function of proteins that recognize N6-methyladenosine modifications to mRNA to mediate m6A-dependent functions, such as by modulating the activity of a m6A reader (e.g., an RNA binding protein that recognizes methylated adenosine). Thus, modulation of the molecule in the m6A mRNA modification pathway modulator may result in modulation of the activity and/or expression of a molecule upstream or downstream of an m6A mRNA modification process.


In one aspect, the modulation of the m6A mRNA modification pathway involves modulation of a molecule selected from the group consisting of m6A mRNA modification readers, m6A mRNA modification writers, m6A mRNA modification erasers and combinations thereof. Non-limiting examples of m6A modification writers include methyltransferases that are capable of post-transcriptionally installing the m6A modification in messenger RNA, and can include any selected from the group consisting of METTL3, METTL14, WTAP, KIAA1429 and combinations thereof. Non-limiting examples of m6A modification erasers include demethylases that are capable of reversing the methylation, and can include any selected from the group consisting of FTI, ALKBH5 and combinations thereof. M6A modification readers include proteins that are capable of selectively binding m6A-methylated mRNA to exert regulatory functions through selective recognition of methylated mRNA. Suitable m6A modification readers can include any selected from the group consisting of Ythdf1, Ythdf2, Ythdf3, Ythdc1, Ythdc2, HNRNPC, HNRNPA2B1, elF3 and combinations thereof. According to one aspect, the m6A modification readers comprise proteins of the YTH domain family of proteins, which includes Ythdf1, Ythdf2, Ythdf3, Ythdc1, Ythdc2 and combinations thereof. (see, e.g., Wang et al. Nature, 505(7481):117-120, 2014; Frayling et al. Science, 316: 889-894, 2007; Zheng et al. Mol. Cell., 49: 18-29, 2012; Cao et al. Open Biol., 6(4): 160003, 2016; Maity et al. The FEBS Journal, 283(9): 1607-1630, 2016).


As used herein, “introducing a mutation” means any conventional method for producing an alteration in the genetic makeup of the stem cell population and/or CAR T-cell population. Non-limiting examples for introducing a mutation into a stem cell population and/or CAR T-cell population include mutagenesis via ultra-violet light irradiation, chemical mutagenesis, targeted mutagenesis such as site directed mutagenesis of a stem cell and/or CAR T-cell, and creation of a transgenic mouse. According to one aspect, a mutation may be introduced into the stem cell and/or CAR T-cell to delete, replace or reduce expression of a gene that expresses a molecule in the m6A mRNA modification pathway, such as a molecule selected from the group consisting of a m6A mRNA modification reader, a m6A mRNA modification writer, a m6A mRNA modification eraser and combinations thereof. In one aspect, the mutation is introduced to delete, replace or reduce expression of a gene that expresses a m6A mRNA modification reader, such as any selected from the group consisting of Ythdf1, Ythdf2, Ythdf3, Ythdc1, Ythdc2, HNRNPC, HNRNPA2B1, elF3 and combinations thereof. In a preferred aspect, a mutation is introduced to delete, replace or reduce expression of a gene that expresses Ythdf2. In yet another aspect, the mutation is introduced to delete, replace or reduce expression of a gene that expresses a m6A mRNA modification writer, such as any selected from the group consisting of METTL3, METTL14, WTAP, KIAA1429 and combinations thereof. In yet another aspect, the mutation is introduced to delete, replace or reduce expression of a gene that expresses a m6A mRNA modification eraser, such as any selected from the group consisting of FTI, ALKBH5 and combinations thereof.


In one aspect, the mutation can be introduced by exposing the stem cells and/or CAR T-cells to a Mx1-Cre targeting system (see, e.g., Kuhn et al. Science, 269(5229): 1427-1429, 1995) that inactivates or deletes at least a portion of a gene that expresses a molecule in the m6A mRNA modification pathway. In yet another aspect, a mutation is introduced that incorporates short hairpin RNA (shRNA) into the stem cells and/or CAR T-cells to reduce expression of a gene that expresses a molecule in the m6A mRNA modification pathway. For example, the shRNA may be introduced by exposing the stem cells and/or CAR T-cells to a vector to deliver shRNA, which may be a viral vector such as lentivirus (see, e.g., Chira et al. Oncotarget, 6(31): 30675-30703, 2015). The shRNA may be capable of triggering gene silencing to regulate gene expression (see, e.g., Paddison et al. Genes Dev., 16(8): 948-958, 2002).


As used herein, “a modulator of a NM-Methyladenosine mRNA modification pathway” (or “m6A mRNA modification pathway modulator”) is any agent that regulates the activity of any member of the m6A mRNA modification pathway, which results in, e.g., an increase or decrease in N6-methyladenosine modifications in mRNA, and/or a change in the types and/or distributions of such modifications in mRNA, such as by modulating the activity of one or more of a m6A writer (e.g. methyltransferase) and m6A eraser (e.g. demethylase). As another example, the agent may be one that increases or decreases activity of proteins that recognize N6-methyladenosine modifications to mRNA to mediate m6A-dependent functions, such as by modulating the activity of a m6A reader (e.g., an RNA binding protein that recognizes methylated adenosine). Thus, the m6A mRNA modification pathway modulator may act on, or upstream of, or downstream of, an agent that affects the m6A modification to mRNA.


In one embodiment, the m6A mRNA modification pathway may be modulated by down-regulating and/or inhibiting a member of the m6A mRNA modification pathway, such as down-regulating and/or inhibiting a m6A mRNA modification reader. As used herein, “down-regulating” means inhibiting or reducing the amount of or inhibiting or decreasing the activity of a member of the m6A mRNA modification pathway. Such down-regulation may be accomplished using, e.g. antisense RNA, siRNA, antibodies, or small molecules. As another example, the m6A mRNA modification reader may be down-regulated by contacting the stem cells and/or CAR T-cells with an inhibitor of an m6A mRNA reader, to inhibit binding and/or recognizing of the m6A modified mRNA by the m6A mRNA reader. In one aspect, the m6A mRNA modification reader that is down-regulated is selected from the group consisting of Ythdf1, Ythdf2, Ythdf3, Ythdc1, Ythdc2, HNRNPC, HNRNPA2B1, elF3 and combinations thereof.

In the present invention, the term “small molecule” includes any chemical or other moiety, other than polypeptides and nucleic acids, that can act to affect biological processes, particularly to modulate members of the m6A mRNA modification pathway. Small molecules can include any number of therapeutic agents presently known and used, or that can be synthesized in a library of such molecules for the purpose of screening for biological function(s). Small molecules are distinguished from macromolecules by size. The small molecules of the present invention usually have a molecular weight less than about 5,000 daltons (Da), preferably less than about 2,500 Da, more preferably less than 1,000 Da, most preferably less than about 500 Da.


Small molecules include without limitation organic compounds, peptidomimetics and conjugates thereof. As used herein, the term “organic compound” refers to any carbon-based compound other than macromolecules such as nucleic acids and polypeptides. In addition to carbon, organic compounds may contain calcium, chlorine, fluorine, copper, hydrogen, iron, potassium, nitrogen, oxygen, sulfur and other elements. An organic compound may be in an aromatic or aliphatic form. Non-limiting examples of organic compounds include acetones, alcohols, anilines, carbohydrates, monosaccharides, oligosaccharides, polysaccharides, amino acids, nucleosides, nucleotides, lipids, retinoids, steroids, proteoglycans, ketones, aldehydes, saturated, unsaturated and polyunsaturated fats, oils and waxes, alkenes, esters, ethers, thiols, sulfides, cyclic compounds, heterocyclic compounds, imidizoles, and phenols. An organic compound as used herein also includes nitrated organic compounds and halogenated (e.g., chlorinated) organic compounds.


Preferred small molecules are relatively easier and less expensively manufactured, formulated or otherwise prepared. Preferred small molecules are stable under a variety of storage conditions. Preferred small molecules may be placed in tight association with macromolecules to form molecules that are biologically active and that have improved pharmaceutical properties. Improved pharmaceutical properties include changes in circulation time, distribution, metabolism, modification, excretion, secretion, elimination, and stability that are favorable to the desired biological activity. Improved pharmaceutical properties include changes in the toxicological and efficacy characteristics of the chemical entity.


In general, a polypeptide mimetic (“peptidomimetic”) is a molecule that mimics the biological activity of a polypeptide, but that is not peptidic in chemical nature. While, in certain embodiments, a peptidomimetic is a molecule that contains no peptide bonds (that is, amide bonds between amino acids), the term peptidomimetic may include molecules that are not completely peptidic in character, such as pseudo-peptides, semi-peptides, and peptoids.


As used herein, the term “biologic” means products derived from living sources as opposed to a chemical process. Non-limiting examples of a “biologic” include proteins, conditioned media, and partially purified products from tissues.


The terms “peptide,” “polypeptide,” and “protein” are used interchangeably herein. In the present invention, these terms mean a linked sequence of amino acids, which may be natural, synthetic, or a modification or combination of natural and synthetic. The term includes antibodies, antibody mimetics, domain antibodies, lipocalins, and targeted proteases. The term also includes vaccines containing a peptide or peptide fragment intended to raise antibodies against the peptide or peptide fragment.


“Antibody” as used herein includes an antibody of classes IgG, IgM, IgA, IgD, or IgE, or fragments or derivatives thereof, including Fab, F(ab′)2, Fd, and single chain antibodies, diabodies, bispecific antibodies, and bifunctional antibodies. The antibody may be a monoclonal antibody, polyclonal antibody, affinity purified antibody, or mixtures thereof, which exhibits sufficient binding specificity to a desired epitope or a sequence derived therefrom. The antibody may also be a chimeric antibody. The antibody may be derivatized by the attachment of one or more chemical, peptide, or polypeptide moieties known in the art. The antibody may be conjugated with a chemical moiety. The antibody may be a human or humanized antibody. These and other antibodies are disclosed in U.S. Published Patent Application No. 20070065447.


Other antibody-like molecules are also within the scope of the present invention. Such antibody-like molecules include, e.g., receptor traps (such as entanercept), antibody mimetics (such as adnectins, fibronectin based “addressable” therapeutic binding molecules from, e.g., Compound Therapeutics, Inc.), domain antibodies (the smallest functional fragment of a naturally occurring single-domain antibody (such as, e.g., nanobodies; see, e.g., Cortez-Retamozo et al., Cancer Res. 2004 Apr. 15; 64(8):2853-7)).


Suitable antibody mimetics generally can be used as surrogates for the antibodies and antibody fragments described herein. Such antibody mimetics may be associated with advantageous properties (e.g., they may be water soluble, resistant to proteolysis, and/or be nonimmunogenic). For example, peptides comprising a synthetic beta-loop structure that mimics the second complementarity-determining region (CDR) of monoclonal antibodies have been proposed and generated. See, e.g., Saragovi et al., Science. Aug. 16, 1991; 253(5021):792-5. Peptide antibody mimetics also have been generated by use of peptide mapping to determine “active” antigen recognition residues, molecular modeling, and a molecular dynamics trajectory analysis, so as to design a peptide mimic containing antigen contact residues from multiple CDRs. See, e.g., Cassett et al., Biochem Biophys Res Commun. Jul. 18, 2003; 307(1):198-205. Additional discussion of related principles, methods, etc., that may be applicable in the context of this invention are provided in, e.g., Fassina, Immunomethods. October 1994; 5(2):121-9.


As used herein, “peptide” includes targeted proteases, which are capable of, e.g., substrate-targeted inhibition of post-translational modification such as disclosed in, e.g., U.S. Patent Application Publication No. 20060275823.


“Antisense” molecules as used herein include antisense or sense oligonucleotides comprising a single-stranded nucleic acid sequence (either RNA or DNA) capable of binding to target mRNA (sense) or DNA (antisense) sequences. The ability to derive an antisense or a sense oligonucleotide, based upon a cDNA sequence encoding a given protein is described in, for example, Stein and Cohen, Cancer Res. 48:2659, (1988) and van der Krol et al., BioTechniques 6:958, (1988).


Antisense molecules can be modified or unmodified RNA, DNA, or mixed polymer oligonucleotides. These molecules function by specifically binding to matching sequences resulting in inhibition of peptide synthesis (Wu-Pong, November 1994, BioPharm, 20-33) either by steric blocking or by activating an RNase H enzyme. Antisense molecules can also alter protein synthesis by interfering with RNA processing or transport from the nucleus into the cytoplasm (Mukhopadhyay & Roth, 1996, Crit. Rev. in Oncogenesis 7, 151-190). In addition, binding of single stranded DNA to RNA can result in nuclease-mediated degradation of the heteroduplex (Wu-Pong, supra). Backbone modified DNA chemistry, which have thus far been shown to act as substrates for RNase H are phosphorothioates, phosphorodithioates, borontrifluoridates, and 2′-arabino and 2′-fluoro arabino-containing oligonucleotides.


Antisense molecules may be introduced into a cell containing the target nucleotide sequence by formation of a conjugate with a ligand binding molecule, as described, e.g., in WO 91/04753. Suitable ligand binding molecules include, but are not limited to, cell surface receptors, growth factors, other cytokines, or other ligands that bind to cell surface receptors. Preferably, conjugation of the ligand binding molecule does not substantially interfere with the ability of the ligand binding molecule to bind to its corresponding molecule or receptor, or block entry of the sense or antisense oligonucleotide or its conjugated version into the cell. Alternatively, a sense or an antisense oligonucleotide may be introduced into a cell containing the target nucleic acid sequence by formation of an oligonucleotide-lipid complex, as described, e.g., in WO 90/10448.


The term small interfering RNA (“siRNA”) refers to small inhibitory RNA duplexes that induce the RNA interference (RNAi) pathway. (Elbashir, S. M. et al. Nature 411:494-498 (2001); Caplen, N. J. et al. Proc. Natl. Acad. Sci. USA 98:9742-9747 (2001); Harborth, J. et al. J Cell Sci. 114:4557-4565 (2001).) These molecules can vary in length (generally 18-30 base pairs) and contain varying degrees of complementarity to their target mRNA in the antisense strand. Some, but not all, siRNA have unpaired overhanging bases on the 5′ or 3′ end of the sense strand and/or the antisense strand. The term “siRNA” includes duplexes of two separate strands, as well as single strands that can form hairpin structures comprising a duplex region. As used herein, siRNA molecules are not limited to RNA molecules but further encompass chemically modified nucleotides and non-nucleotides. siRNA gene-targeting may be carried out by transient siRNA transfer into cells (achieved by such classic methods as liposome-mediated transfection, electroporation, or microinjection).


In an additional aspect of the present invention, the number of stem cells and/or CAR T-cells is increased by a factor of at least 2-fold. Preferably, the number of stem cells and/or CAR T-cells is increased by a factor of at least 2.5 fold, at least 3 fold, at least 3.5 fold, at least 4-fold, such as at least 5-fold, including at least 8-fold, at least 10-fold, at least 15-fold, at least 20-fold, or more. Surprisingly and unexpectedly such levels of stem cell and/or CAR T-cell expansion are achieved using the methods of the present invention.


As noted above, the methods of the present invention may be used to expand any population of stem cells. Preferably, the stem cells that may be expanded according to the methods of the present invention may selected from hematopoietic stem cells (HSCs), hematopoietic stem and progenitor cells (HSPCs), endothelial progenitor cells (EPCs), mesenchymal stem cells (MSCs), cardiac stem cells (CSCs), neuronal stem cells (NSCs), and combinations thereof. According to one aspect, the stem cells are HSCs. According to yet another aspect, the stem cells are MSCs.


The methods of the present invention may also be capable of expanding stem cells such that the expanded cells have at least a 5-fold increase in total colony-forming units (CFU), such as an 8-fold, 10-fold, and even 15-fold or more increase. Further, the methods may be capable of providing an increase in CFU-granulocyte erythrocyte monocyte megakaryocyte (GEMM) colonies of at least 3.8-fold, such as at least 4-fold, 5-fold, and even at least 8-fold or more.


Another embodiment of the invention is a method for ex vivo expansion of a substantially undifferentiated stem cell population. This method comprises modulating a N6-methyladenosine mRNA modification pathway in the undifferentiated stem cell population to expand the number of undifferentiated stem cells without significant differentiation of the stem cell population.


In this embodiment, a stem cell population is “substantially undifferentiated” if a sufficient number of cells in that population retain the ability to self-renew and can give rise to various differentiated cell types when transplanted into a recipient, for example, in the case of an HSC population, repopulating the HSC lineage when transplanted (or in the case of an MSC population, repopulating the MSC lineage when transplanted). As used herein, “without significant differentiation” means the expanded stem cell population has a sufficient number of cells that maintain a multi-lineage differentiation potential so that the full scope of a target stem lineage may be regenerated upon transplantation of the expanded stem cell population into a recipient. Thus, e.g., in the case of an HSC population, the expanded HSC population, when transplanted into a recipient, is capable of regenerating the entire hematopoietic cell lineage. In the case of a MSC population, the expanded MSC population, when transplanted into a recipient, is capable of regenerating the entire mesenchymal cell lineage.


Another embodiment is a method for ex vivo expansion of a chimeric antigen receptor (CAR) T-cell population. This method comprises modulating a N6-Methyladenosine (m6A) mRNA modification pathway in the CAR T-cell population to expand the number of CAR T-cells.


A further embodiment of the invention is a method for ex vivo expansion of an hematopoietic stem cell (HSC) population obtained from a tissue selected from the group consisting of peripheral blood, cord blood, and bone marrow. This method comprises modulating a N6-methyladenosine mRNA modification pathway in the HSC population to expand the HSC population to a sufficient quantity while maintaining a multilineage differentiation potential in the HSC population, which is sufficient for subsequent transplantation into a subject in need thereof.


A further embodiment of the invention is a method for ex vivo expansion of a mesenchymal stem cell (MSC) population obtained from a tissue selected from the group consisting of peripheral blood, cord blood, and bone marrow. This method comprises modulating a N6-methyladenosine mRNA modification pathway in the MSC population to expand the MSC population to a sufficient quantity while maintaining a multilineage differentiation potential in the MSC population, which is sufficient for subsequent transplantation into a subject in need thereof.


A further embodiment of the invention is a method for ex vivo expansion of a chimeric antigen receptor (CAR) T-cell population prepared by modifying T-cells obtained from a tissue selected from the group consisting of peripheral blood, cord blood, and bone marrow. The method comprising modulating a N6-Methyladenosine (m6A) mRNA modification pathway in the CAR T-cell population to expand the CAR T-cell population to a sufficient quantity which is sufficient for subsequent transplantation into a subject in need thereof.


As used herein, “obtained” from a tissue means any conventional method of harvesting or partitioning tissue from a donor. As noted previously, the tissue may be any tissue that contains a stem cell such as an HSC and/or MSC, and/or a T-cell that is capable of being modified with chimeric antigen receptors. Thus, for example, the tissue may be obtained from a blood sample, such as a peripheral or cord blood sample, or harvested from bone marrow. Methods for obtaining such samples are well known to the artisan. In the present invention, the samples may be fresh, i.e., obtained from the donor without freezing. Moreover, the samples may be further manipulated to remove extraneous or unwanted components prior to expansion. The samples may also be obtained from a preserved stock. For example, in the case of peripheral or cord blood, the samples may be withdrawn from a cryogenically or otherwise preserved bank of such blood. Such samples may be obtained from any suitable donor. Preferably, the donor is a mammal, for example, a primate, such as a human. Furthermore, the sample may be obtained from an autologous or allogeneic donor or source. Preferably, the sample is obtained from an autologous source.


In this method, “maintaining a multilineage differentiation potential” means that the expanded HSC and/or MSC population has the ability, when transplanted into a subject in need of such a transplant, to regenerate all the types of progenitor cells e.g., CMP, GMP, MEP, and CLP, and ultimately all the types of blood cells including, e.g., red blood cells, B lymphocytes, T lymphocytes, natural killer cells, neutrophils, basophils, eosinophils, monocytes, macrophages, and platelets in the hematopoietic system.


In the present invention, that quantity of expanded HSCs and/or MSCs and/or CAR T-cells, which is “sufficient for subsequent transplantation” generally corresponds to that number of HSCs and/or MSCs and/or CAR T-cells, which would result in greater than about 1% engraftment after transplantation. This is one accepted measure of a successful transplant. In the present invention, any conventional method may be used to determine the % engraftment, including the one set forth in the Examples. Such a measure may be carried out with or without competitor cells, typically and preferably, without competitor cells. (Zhang, C. C., et al., Nat Med, 12(2): 240-5, 2006. Zhang, C. C. and H. F. Lodish, Blood, 105(11): 4314-20, 2005).


In the above described ex vivo expansion methods, modulating the N6-methyladenosine mRNA modification pathway may be achieved as previously set forth. Modulating the N6-methyladenosine mRNA modification pathway may include introducing a mutation into the stem cells and/or CAR T-cells that results in modulation of a molecule in the m6A mRNA modification pathway, or contacting the stem cells and/or CAR T-cells with a modulator of a molecule in the m6A mRNA modification pathway selected from the group consisting of a small molecule, a biologic, an antisense RNA, a small interfering RNA (siRNA), and combinations thereof.


In one aspect of the ex vivo expansion methods, the modulation of the m6A mRNA modification pathway involves modulation of a molecule selected from the group consisting of m6A mRNA modification readers, m6A mRNA modification writers, m6A mRNA modification erasers, and combinations thereof. Non-limiting examples of m6A modification writers include methyltransferases that are capable of post-transcriptionally installing the m6A modification in messenger RNA, and can include any selected from the group consisting of METTL3, METTL14, WTAP, KIAA1429 and combinations thereof. Non-limiting examples of m6A modification erasers include demethylases that are capable of reversing the methylation, and can include any selected from the group consisting of FTI, ALKBH5 and combinations thereof. M6A modification readers include proteins that are capable of selectively binding m6A-methylated mRNA to exert regulatory functions through selective recognition of methylated mRNA. Suitable m6A modification readers can include any selected from the group consisting of Ythdf1, Ythdf2, Ythdf3, Ythdc1, Ythdc2, HNRNPC, HNRNPA2B1, elF3 and combinations thereof. According to one aspect, the m6A modification readers comprise proteins of the YTH domain family of proteins, which includes Ythdf1, Ythdf2, Ythdf3, Ythdc1, Ythdc2 and combinations thereof. (see, e.g., Wang et al. Nature, 505(7481):117-120, 2014; Frayling et al. Science, 316: 889-894, 2007; Zheng et al. Mol. Cell., 49: 18-29, 2012; Cao et al. Open Biol., 6(4): 160003, 2016; Maity et al. The FEBS Journal, 283(9): 1607-1630, 2016).


In one aspect of the ex vivo methods, modulating the m6A mRNA modification pathway comprises introducing a mutation into the stem cells and/or CAR-T cells to delete, replace, or reduce expression of a gene that expresses a molecule in the m6A mRNA modification pathway. For example, the mutation deletes, replaces or reduces expression of a gene that expresses a molecule selected from the group consisting of a m6A mRNA modification reader, a m6A mRNA modification writer, a m6A mRNA eraser, and combinations thereof. In one aspect, the mutation deletes, replaces or reduces expression of a gene that expresses a m6A mRNA modification reader, such as a m6A mRNA modification reader selected from the group consisting of Ythdf1, Ythdf2, Ythdf3, Ythdc1, HNRNPC, HNRNPA2B1, elF3, and combinations thereof. In a preferred aspect, the mutation deletes, replaces or reduces expression of a gene that expresses Ythdf2. In yet another aspect, the mutation deletes, replaces or reduces expression of a gene that expresses a m6A mRNA modification eraser, such as a m6A mRNA modification eraser selected from the group consisting of FTO, ALKBH5 and combinations thereof. In yet another aspect, the mutation deletes, replaces or reduces expression of a gene that expresses a m6A mRNA modification writer, such as a m6A mRNA modification writer selected from the group consisting of METTL3, METTL14, WTAP, KIAA1429 and combinations thereof.


In one aspect of the ex vivo expansion methods, the mutation can be introduced by any of the methods previously disclosed herein. For example, the mutation can be introduced by exposing the stem cells and/or CAR T-cells to a Mx1-Cre targeting system (see, e.g., Kuhn et al. Science, 269(5229): 1427-1429, 1995) that inactivates or deletes at least a portion of a gene that expresses a molecule in the m6A mRNA modification pathway. In yet another aspect, a mutation is introduced that incorporates short hairpin RNA (shRNA) into the stem cells and/or CAR T-cells to reduce expression of a gene that expresses a molecule in the m6A mRNA modification pathway. For example, the shRNA may be introduced by exposing the stem cells and/or CAR-T cells to a vector to deliver shRNA, which may be a viral vector such as lentivirus (see, e.g., Chira et al. Oncotarget, 6(31): 30675-30703, 2015). The shRNA may be capable of triggering gene silencing to regulate gene expression (see, e.g., Paddison et al. Genes Dev., 16(8): 948-958, 2002).


In these ex vivo expansion methods, according to one aspect, modulating of the m6A mRNA modification pathway comprises down-regulating and/or inhibiting a member of the m6A mRNA modification pathway, such as down-regulating and/or inhibiting a m6A mRNA modification reader. As used herein, “down-regulating” means inhibiting or reducing the amount of or inhibiting or decreasing the activity of a member of the m6A mRNA modification pathway. Such down-regulation may be accomplished using, e.g. antisense RNA, siRNA, antibodies, or small molecules. As another example, the m6A mRNA modification reader may be down-regulated by contacting the stem cells and/or CAR T-cells with an inhibitor of an m6A mRNA reader, to inhibit binding and/or recognizing of the m6A modified mRNA by the m6A mRNA reader. In one aspect, the m6A mRNA modification reader that is down-regulated is selected from the group consisting of Ythdf1, Ythdf2, Ythdf3, Ythdc1, Ythdc2, HNRNPC, HNRNPA2B1, elF3 and combinations thereof. In a preferred aspect, the m6A mRNA modification reader that is down-regulated is Ythdf2. The RNA decay role of Ythdf2 has been previously elucidated (see, e.g., Wang et al. Nature 505(7481): 117-120, 2014). Inhibitors of the m6A mRNA modification reader may be any selected from the group consisting of: (inhibitors of HNRNPC) hsa-let-7e-5p (MIRT051596), hsa-mir-455-3p (MIRT037890), hsa-mir-30c-5p (MIRT047904), hsa-mir-186-5p (MIRT045150), hsa-mir-744-5p (MIRT037494), hsa-mir-18a-3p (MIRT040851), hsa-mir-484 (MIRT042196), hsa-mir-505-5p (MIRT037959), hsa-mir-615-3p (MIRT039991), hsa-mir-342-3p (MIRT043694), hsa-miR-3607-3p, hsa-miR-30d, hsa-miR-3916, hsa-miR-3162-5p, hsa-miR-1273d, hsa-miR-3161, hsa-miR-30a, hsa-miR-629, hsa-miR-208b, hsa-miR-489, hsa-miR-3148, hsa-miR-2113, hsa-miR-877, hsa-miR-455-5p, hsa-miR-186, hsa-miR-548o, hsa-miR-3139, hsa-miR-320a, hsa-miR-4311, hsa-miR-555, hsa-miR-3605-5p, hsa-miR-515-5p, hsa-miR-144, hsa-miR-499-5p, hsa-miR-1323, hsa-miR-548x, hsa-miR-299-5p, hsa-miR-653, hsa-miR-576-5p, hsa-miR-548p, hsa-miR-586, hsa-miR-888, hsa-miR-3647-3p, hsa-miR-484, hsa-miR-320b, hsa-miR-620, hsa-miR-30b, hsa-miR-548q, hsa-miR-29b-1, hsa-miR-570, hsa-miR-183, hsa-miR-1276, hsa-miR-208a, hsa-miR-186, hsa-miR-28-5p, hsa-miR-330-3p, hsa-miR-548am, hsa-miR-320d, hsa-miR-3175, hsa-miR-3155, hsa-miR-548aa, hsa-miR-519e, hsa-miR-1270, hsa-miR-513b, hsa-miR-599, hsa-miR-518f, hsa-miR-4301, hsa-miR-30c, hsa-miR-3135, hsa-miR-4286, hsa-miR-202, hsa-miR-4263, hsa-miR-4299, hsa-miR-606, hsa-miR-3133, hsa-miR-583, hsa-miR-3125, hsa-miR-501-5p, hsa-miR-7-1, hsa-miR-514b-3p, hsa-miR-3155b, hsa-miR-548d-3p, hsa-miR-224, hsa-miR-7-2, hsa-miR-708, hsa-miR-3199, hsa-miR-514, hsa-miR-30e (see, e.g. Helwak et al. Cell, 153(3): 654-655, 2013; Whisnant et al., M Bio 4(2), 2013:e000193); (inhibitors of HNRNPA2B1) hsa-mir-92a-3p (MIRT049721), hsa-mir-30c-5p (MIRT048009), hsa-mir-191-5p (MIRT045809), hsa-let-7f-5p (MIRT051404), hsa-mir-27b-3p (MIRT046213), hsa-mir-877-3p (MIRT037116), hsa-mir-615-3p (MIRT040278), hsa-mir-1260b (MIRT052680), hsa-mir-103a-3p (MIRT027027), hsa-mir-16-5p (MIRT031508), hsa-mir-1296-5p (MIRT036075), hsa-mir-197-3p (MIRT048098), hsa-miR-548j, hsa-miR-3678-3p, hsa-miR-607, hsa-miR-188-5p, hsa-miR-15a, hsa-miR-3653, hsa-miR-371-5p, hsa-miR-550a, hsa-miR-3622b-3p, hsa-miR-548a-5p, hsa-miR-3170, hsa-miR-3148, hsa-miR-556-3p, hsa-miR-490-3p, hsa-miR-559, hsa-miR-200c, hsa-miR-130a, hsa-miR-548y, hsa-miR-548o, hsa-miR-23c, hsa-miR-491-3p, hsa-miR-335, hsa-miR-3667-3p, hsa-miR-466, hsa-miR-23b, hsa-miR-4310, hsa-miR-127-5p, hsa-miR-548b-5p, hsa-miR-616, hsa-miR-16, hsa-miR-338-3p, hsa-miR-3200-5p, hsa-miR-362-3p, hsa-miR-448, hsa-miR-1306, hsa-miR-944, hsa-miR-3684, hsa-miR-373, hsa-miR-103a, hsa-miR-380, hsa-miR-499-5p, hsa-miR-1323, hsa-miR-323-5p, hsa-miR-3674, hsa-miR-1252, hsa-miR-33b, hsa-miR-580, hsa-miR-548c-3p, hsa-miR-103a-2, hsa-miR-548w, hsa-miR-600, hsa-miR-634, hsa-miR-586, hsa-miR-497, hsa-miR-720, hsa-miR-654-3p, hsa-miR-524-5p, hsa-miR-543, hsa-miR-548q, hsa-let-7f-2, hsa-miR-330-5p, hsa-miR-500a, hsa-miR-548I, hsa-miR-570, hsa-miR-374a, hsa-miR-1184, hsa-miR-649, hsa-miR-424, hsa-miR-3658, hsa-miR-186, hsa-miR-326, hsa-miR-548d-5p, hsa-miR-23a, hsa-miR-15b, hsa-miR-190, hsa-miR-203, hsa-miR-548h, hsa-miR-3136-5p, hsa-miR-618, hsa-miR-551b, hsa-miR-211, hsa-miR-1305, hsa-miR-513b, hsa-miR-96, hsa-miR-2117, hsa-miR-548n, hsa-miR-3910, hsa-miR-217, hsa-miR-892b, hsa-miR-502-5p, hsa-miR-548i, hsa-miR-520d-5p, hsa-miR-4299, hsa-miR-1285, hsa-miR-3133, hsa-miR-483-3p (see, e.g., Hafner et al.

According to one embodiment, the invention comprises an isolated population of mesenchymal stem cells made by any of the processes described herein. For example, the invention in certain embodiments can comprise an expanded, isolated population of mesenchymal stem cells made by any of the expansion and/or isolation processes described herein.


In one embodiment, a kit for isolating a mesenchymal stem cell (MSC) population for subsequent transplantation into a subject in need thereof is provided. The kit comprises a system for contacting a biological sample comprising MSCs with one or more N-cadherin antibodies, and instructions for use thereof. In one embodiment, the kit further comprises a system for expanding the population of MSCs by introducing a mutation into the MSC population that results in deletion, replacement or reduced expression of a gene expressing a m6A mRNA modification reader, and instructions for use thereof. In yet another embodiment, the system for introducing a mutation into the MSC population includes one or more reagents capable of introducing a mutation into the MSC population that results in deletion, replacement or reduced expression of a gene expressing Ythdf2. In yet another embodiment, the system for introducing a mutation into the MSC population comprises a Mx1-Cre targeting system that inactivates or deletes at least a portion of a gene that expresses a m6A mRNA modification reader. In one embodiment, the system for introducing a mutation into the MSC population comprises reagents for delivering a lentivirus that incorporates shRNA into the MSC population to reduce expression of a gene that expresses a m6A mRNA modification reader.


According to another embodiment of the invention, a method for administering a mesenchymal stem cell (MSC) to a subject in need thereof is provided. The method comprises isolating MSCs from a biological sample comprising a population of MSCs, by contacting the biological sample with one or more N-cadherin antibodies, and administering the isolated MSCs to the subject. Furthermore, in one embodiment, the method further comprises introducing, into the biological sample containing the MSC population, a mutation that results in deletion, replacement or reduced expression of a gene expressing a m6A mRNA modification reader, and culturing the biological sample in a suitable culture media for a period of time sufficient to expand the number of MSCs in the sample to a number sufficient to transplant into the subject. In one embodiment, wherein the mutation results in deletion a gene expressing Ythdf2. In one embodiment, the mutation results in incorporation of shRNA into the HSC population that reduces expression of a gene expressing Ythdf2. According to yet another aspect, the MSCs are obtained from a biological sample comprising a tissue selected from the group consisting of cord blood, peripheral blood, and bone marrow.


According to yet another embodiment, a method for reconstituting bone marrow in a subject in need thereof is provided. The method comprises isolating mesenchymal stem cells (MSCs) from a biological sample comprising a population of MSCs, by contacting the biological sample with one or more N-cadherin antibodies, and administering the isolated MSCs to the subject. Furthermore, according to one aspect, the method further comprises introducing, into the biological sample containing the MSC population, a mutation that results in deletion, replacement or reduced expression of a gene expressing a m6A mRNA modification reader, and culturing the sample in a suitable culture media for a period of time sufficient to expand the number of MSCs in the sample to a number sufficient to transplant into the subject. In one embodiment, the MSCs are obtained from a biological sample comprising a tissue selected from the group consisting of cord blood, peripheral blood, and bone marrow.


According to yet another embodiment, a method for treating a subject in need of a transplant, selected from the group consisting of a bone marrow transplant, a peripheral blood transplant and an umbilical cord blood transplant comprising administering to the subject a population of isolated MSCs obtained by any of the methods described herein. According to embodiment, the sample is from an autologous or allogeneic source. According to yet another embodiment, the sample is from an autologous source.


In the present invention, a “therapeutically effective amount” is an amount sufficient to effect beneficial or desired results. In terms of treatment of a mammal, a “therapeutically effective amount” of a modulator and/or expanded cells is an amount sufficient to treat, manage, palliate, ameliorate, or stabilize a condition, such as a bone marrow disease, in the mammal. A therapeutically effective amount can be administered in one or more doses.


The therapeutically effective amount is generally determined by a physician on a case-by-case basis and is within the skill of one in the art. Several factors are typically taken into account when determining an appropriate dosage. These factors include age, sex and weight of the subject, the condition being treated, the severity of the condition and the form of the drug being administered.


Effective dosage forms, modes of administration, and dosage amounts may be determined empirically, and making such determinations is within the skill of the art. It is understood by those skilled in the art that the dosage amount will vary with the route of administration, the rate of excretion, the duration of the treatment, the identity of any other drugs being administered, the age, size, and species of animal, and like factors well known in the arts of medicine and veterinary medicine. In general, a suitable dose of a modulator according to the invention will be that amount of the modulator, which is the lowest dose effective to produce the desired effect. The effective dose of a modulator maybe administered as two, three, four, five, six or more sub-doses, administered separately at appropriate intervals throughout the day.


A modulator may be administered in any desired and effective manner: as pharmaceutical compositions for oral ingestion, or for parenteral or other administration in any appropriate manner such as intraperitoneal, subcutaneous, topical, intradermal, inhalation, intrapulmonary, rectal, vaginal, sublingual, intramuscular, intravenous, intraarterial, intrathecal, or intralymphatic. Further, a modulator of the present invention may be administered in conjunction with other treatments. A modulator of the present invention maybe encapsulated or otherwise protected against gastric or other secretions, if desired.


While it is possible for a modulator of the invention to be administered alone, it is preferable to administer the modulator as a pharmaceutical formulation (composition). Such pharmaceutical formulations typically comprise one or more modulators as an active ingredient in admixture with one or more pharmaceutically-acceptable carriers and, optionally, one or more other compounds, drugs, ingredients and/or materials. Regardless of the route of administration selected, the modulator of the present invention may be formulated into pharmaceutically-acceptable dosage forms by conventional methods known to those of skill in the art.

Pharmaceutically acceptable carriers are well known in the art (see, e.g., Remington's Pharmaceutical Sciences (Mack Publishing Co., Easton, Pa.) and The National Formulary (American Pharmaceutical Association, Washington, D.C.)) and include sugars (e.g., lactose, sucrose, mannitol, and sorbitol), starches, cellulose preparations, calcium phosphates (e.g., dicalcium phosphate, tricalcium phosphate and calcium hydrogen phosphate), sodium citrate, water, aqueous solutions (e.g., saline, sodium chloride injection, Ringer's injection, dextrose injection, dextrose and sodium chloride injection, lactated Ringer's injection), alcohols (e.g., ethyl alcohol, propyl alcohol, and benzyl alcohol), polyols (e.g., glycerol, propylene glycol, and polyethylene glycol), organic esters (e.g., ethyl oleate and triglycerides), biodegradable polymers (e.g., polylactide-polyglycolide, poly(orthoesters), and poly(anhydrides)), elastomeric matrices, liposomes, microspheres, oils (e.g., corn, germ, olive, castor, sesame, cottonseed, and groundnut), cocoa butter, waxes (e.g., suppository waxes), paraffins, silicones, talc, silicylate, etc. Each pharmaceutically acceptable carrier used in a pharmaceutical composition comprising a modulator of the invention must be “acceptable” in the sense of being compatible with the other ingredients of the formulation and not injurious to the subject. Carriers suitable for a selected dosage form and intended route of administration are well known in the art, and acceptable carriers for a chosen dosage form and method of administration can be determined using ordinary skill in the art.


Pharmaceutical compositions comprising a modulator of the invention may, optionally, contain additional ingredients and/or materials commonly used in pharmaceutical compositions. These ingredients and materials are well known in the art and include (1) fillers or extenders, such as starches, lactose, sucrose, glucose, mannitol, and silicic acid; (2) binders, such as carboxymethylcellulose, alginates, gelatin, polyvinyl pyrrolidone, hydroxypropylmethyl cellulose, sucrose and acacia; (3) humectants, such as glycerol; (4) disintegrating agents, such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, sodium starch glycolate, cross-linked sodium carboxymethyl cellulose and sodium carbonate; (5) solution retarding agents, such as paraffin; (6) absorption accelerators, such as quaternary ammonium compounds; (7) wetting agents, such as cetyl alcohol and glycerol monosterate; (8) absorbents, such as kaolin and bentonite clay; (9) lubricants, such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, and sodium lauryl sulfate; (10) suspending agents, such as ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar and tragacanth; (11) buffering agents; (12) excipients, such as lactose, milk sugars, polyethylene glycols, animal and vegetable fats, oils, waxes, paraffins, cocoa butter, starches, tragacanth, cellulose derivatives, polyethylene glycol, silicones, bentonites, silicic acid, talc, salicylate, zinc oxide, aluminum hydroxide, calcium silicates, and polyamide powder; (13) inert diluents, such as water or other solvents; (14) preservatives; (15) surface-active agents; (16) dispersing agents; (17) control-release or absorption-delaying agents, such as hydroxypropylmethyl cellulose, other polymer matrices, biodegradable polymers, liposomes, microspheres, aluminum monosterate, gelatin, and waxes; (18) opacifying agents; (19) adjuvants; (20) wetting agents; (21) emulsifying and suspending agents; (22), solubilizing agents and emulsifiers, such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor and sesame oils), glycerol, tetrahydrofuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan; (23) propellants, such as chlorofluorohydrocarbons and volatile unsubstituted hydrocarbons, such as butane and propane; (24) antioxidants; (25) agents which render the formulation isotonic with the blood of the intended recipient, such as sugars and sodium chloride; (26) thickening agents; (27) coating materials, such as lecithin; and (28) sweetening, flavoring, coloring, perfuming and preservative agents. Each such ingredient or material must be “acceptable” in the sense of being compatible with the other ingredients of the formulation and not injurious to the subject. Ingredients and materials suitable for a selected dosage form and intended route of administration are well known in the art, and acceptable ingredients and materials for a chosen dosage form and method of administration may be determined using ordinary skill in the art.


Pharmaceutical compositions suitable for oral administration may be in the form of capsules, cachets, pills, tablets, powders, granules, a solution or a suspension in an aqueous or non-aqueous liquid, an oil-in-water or water-in-oil liquid emulsion, an elixir or syrup, a pastille, a bolus, an electuary or a paste. These formulations may be prepared by methods known in the art, e.g., by means of conventional pan-coating, mixing, granulation or lyophilization processes.


Solid dosage forms for oral administration (capsules, tablets, pills, dragees, powders, granules and the like) may be prepared by mixing the active ingredient(s) with one or more pharmaceutically-acceptable carriers and, optionally, one or more fillers, extenders, binders, humectants, disintegrating agents, solution retarding agents, absorption accelerators, wetting agents, absorbents, lubricants, and/or coloring agents. Solid compositions of a similar type maybe employed as fillers in soft and hard-filled gelatin capsules using a suitable excipient. A tablet may be made by compression or molding, optionally with one or more accessory ingredients. Compressed tablets may be prepared using a suitable binder, lubricant, inert diluent, preservative, disintegrant, surface-active or dispersing agent. Molded tablets may be made by molding in a suitable machine. The tablets, and other solid dosage forms, such as dragees, capsules, pills and granules, may optionally be scored or prepared with coatings and shells, such as enteric coatings and other coatings well known in the pharmaceutical-formulating art. They may also be formulated so as to provide slow or controlled release of the active ingredient therein. They may be sterilized by, for example, filtration through a bacteria-retaining filter. These compositions may also optionally contain opacifying agents and may be of a composition such that they release the active ingredient only, or preferentially, in a certain portion of the gastrointestinal tract, optionally, in a delayed manner. The active ingredient can also be in microencapsulated form.


Liquid dosage forms for oral administration include pharmaceutically-acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. The liquid dosage forms may contain suitable inert diluents commonly used in the art. Besides inert diluents, the oral compositions may also include adjuvants, such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, coloring, perfuming and preservative agents. Suspensions may contain suspending agents.


Pharmaceutical compositions for rectal or vaginal administration may be presented as a suppository, which may be prepared by mixing one or more active ingredient(s) with one or more suitable nonirritating carriers which are solid at room temperature, but liquid at body temperature and, therefore, will melt in the rectum or vaginal cavity and release the active compound. Pharmaceutical compositions which are suitable for vaginal administration also include pessaries, tampons, creams, gels, pastes, foams or spray formulations containing such pharmaceutically-acceptable carriers as are known in the art to be appropriate.


Dosage forms for the topical or transdermal administration include powders, sprays, ointments, pastes, creams, lotions, gels, solutions, patches, drops and inhalants. The active compound may be mixed under sterile conditions with a suitable pharmaceutically-acceptable carrier. The ointments, pastes, creams and gels may contain excipients. Powders and sprays may contain excipients and propellants.


Pharmaceutical compositions suitable for parenteral administrations comprise one or more modulator in combination with one or more pharmaceutically-acceptable sterile isotonic aqueous or non-aqueous solutions, dispersions, suspensions or emulsions, or sterile powders which may be reconstituted into sterile injectable solutions or dispersions just prior to use, which may contain suitable antioxidants, buffers, solutes which render the formulation isotonic with the blood of the intended recipient, or suspending or thickening agents. Proper fluidity can be maintained, for example, by the use of coating materials, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants. These compositions may also contain suitable adjuvants, such as wetting agents, emulsifying agents and dispersing agents. It may also be desirable to include isotonic agents. In addition, prolonged absorption of the injectable pharmaceutical form may be brought about by the inclusion of agents which delay absorption.


In some cases, in order to prolong the effect of a drug containing a modulator of the present invention, it is desirable to slow its absorption from subcutaneous or intramuscular injection. This may be accomplished by the use of a liquid suspension of crystalline or amorphous material having poor water solubility.


The rate of absorption of the drug then depends upon its rate of dissolution which, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally-administered drug may be accomplished by dissolving or suspending the drug in an oil vehicle. Injectable depot forms may be made by forming microencapsule matrices of the active ingredient in biodegradable polymers. Depending on the ratio of the active ingredient to polymer, and the nature of the particular polymer employed, the rate of active ingredient release can be controlled. Depot injectable formulations are also prepared by entrapping the drug in liposomes or microemulsions which are compatible with body tissue. The injectable materials can be sterilized for example, by filtration through a bacterial-retaining filter.


The formulations may be presented in unit-dose or multi-dose sealed containers, for example, ampules and vials, and may be stored in a lyophilized condition requiring only the addition of the sterile liquid carrier, for example water for injection, immediately prior to use. Extemporaneous injection solutions and suspensions may be prepared from sterile powders, granules and tablets of the type described above.


The following examples are provided to further illustrate the methods and compositions of the present invention. These examples are illustrative only and are not intended to limit the scope of the invention in any way.


EXAMPLES

The examples herein examine Ythdf2, a well-recognized m6A reader promoting targeted mRNA decay (Wang et al. Blood, 505: 17-120, 2014), at least partly with the purpose of investigating its role in the context of HSC maintenance. Without being limited to any particular theory, it is believed that manipulation of Ythdf2 might potentially influence the life span of a great number m6A-marked mRNAs, thus impacting adult HSC self-renewal versus differentiation and facilitating HSC expansion. As shown in the examples below, Ythdf2 depletion specifically expands mouse and human HSCs without skewing lineage fate. Accordingly, it is believed that Ythdf2 may play an essential role in regulating HSC self-renewal, and provide a novel approach to enhance hUCB HSCs ex vivo expansion, including in clinical applications.


The examples also show functional definition of the drug-resistant rHSC population, and a finding that rHSCs are maintained in the endosteal niche largely by N-cad+ cells during homeostasis and under chemotherapeutic stress. It is further shown that N-cad+ cells in endosteal zone are mesenchymal stem cells and contribute to rHSC maintenance.


Example A

The following protocols were used in the “A” Examples below.


Mice. Ythdf2 conditional KO mice were generated by Chuan He and Bin Shen group. Mice were housed in the animal facility at Stowers Institute for Medical Research (SIMR) and handled according to Institute and NIH guidelines. All procedures were approved by the IACUC of SIMR.


Flow cytometry and HSPC sorting. Mouse HSPCs, progenitors, and lineage cells were harvested from BM (femur and tibia) and spleen. Red blood cells were lysed using a 0.16 M ammonium chloride solution, and the cells were filtered with 70 μm strainers to generate single cell suspensions. For mouse HSC identification, cells were stained with antibodies against Sca-1 (D7), c-Kit (2B8), CD34 (RAM34), Flk2 (A2F10), CD48 (HM48-1), CD150 (TC15-12F12.2), together with lineage cocktail including CD3 (145-2C11), CD4 (RM4-5), CD8 (53-6.7), Mac-1 (M1/70), Gr1 (RB6-8C5), CD45R (B220, RA3-6B2), IgM (II-41) and Ter119 (TER-119). For progenitors and lineage cells, cells were stained with antibodies as previously described (Qian, P. et al. Cell Stem Cell, 18:214-228, 2016, doi:10.1016/j.stem.2015.11.001). 7-aminoactinomycin D (7-AAD) (A1310, Life technologies) was used to exclude dead cells. Human cord blood samples were acquired from the St. Louis Cord Blood Bank. Mononuclear cells were isolated with Lymphoprep™ (StemCell technologies), followed by isolation of human CD34+ cord blood cells by human CD34 MicroBead Kit UltraPure (Miltenyi Biotec). To quantify human HSPCs, cells were stained with antibodies against CD34 (581), CD38 (HIT2), CD45RA (HI100), CD90 (5E10), CD49f (GoH3), EPCR/CD201 (RCR-401). Cell sorting and analyses were performed on MoFlo (Dako), InFlux Cell Sorter (BD Biosciences), and/or MACSQuant (Miltenyi Biotec). Data analysis was performed using FlowJo software.


Homing assay. In vivo homing assays were performed as previously described (He et al. Methods in Molecular Biology, 1185: 279-284, 2014). Basically, whole bone marrow (WBM) cells from CD45.2 mice were labelled with 5 μM 5-(and −6)-carboxyfluorescein diacetate succinimidyl ester (CFDA SE) (Molecular Probes) at 37° C. for 10 mins, washed three times, and 1×106 WBM were transplanted into lethally irradiated ptprc mice. After 18 hours, femurs and tibias were flushed, and CFDA SE+ cells were determined.


Competitive reconstitution assay. Competitive reconstitution assays were performed by intravenous transplantation of 2×105, 7.5×104 or 2.5×104 donor-derived WBM cells from wt or Ythdf2 KO mice (CD45.2), together with 2×105 rescue cells (CD45.1) into groups of ten lethally irradiated (10 Gy) ptprc recipient mice. For secondary transplantation, primary transplant recipients were sacrificed. BM cells were dissected from femur and tibia, and then transplanted mouse-to-mouse at a dosage of 1×106 cells into irradiated secondary recipient mice. Baytril water was given to recipient mice three days before irradiation and continued for another two weeks after irradiation. Primary and secondary CRU frequencies were measured using ELDA software (Hu et al. Journal of Immunological Methods, 347: 70-78, 2009), in which successful engraftment was defined as the presence of a distinct CD45.2+ CD45.1 population ≥5% and ≥1% of total hematopoietic cells in peripheral blood, respectively (Purton et al. Cell Stem Cell, 1: 263-270, 2007). Also, the secondary transplantation recipient mice that died before 16 weeks post transplantation were counted for failed engraftment.


Cell cycle and apoptosis assays. Cell cycle analysis was performed with FITC mouse anti-human Ki67 set (BD Pharmingen) according to the manufacturer's instructions. Briefly, 5×106 BM cells were isolated and stained with HSC antibodies as described above. Cells were fixed by 4% paraformaldehyde at 4° C. overnight or room temperature (RT) for 1 hour, and then permeabilized with 0.2% triton X-100 on ice for 15 mins. Cells were washed with PBS containing 2% FBS, and then were incubated with Ki-67 antibody at RT for 1 hour in the dark, and SYTOX Red (Invitrogen) at RT for another 5 mins, followed by flow cytometric analysis with InFlux Cell Sorter (BD Biosciences). For apoptosis analysis, Annexin V (Invitrogen) and SYTOX Red staining of 5×106 BM cells was performed according to the manufacturer's protocol.


m6A RNA-IP-seq. Two replicates of 105 LT-HSC, ST-HSC (LSK CD34+ FLK2) and MPP (LSK CD34+ FLK2+) from C57BL/6J mouse were sorted into TRIzol (Invitrogen), and total RNA was isolated according to the manufacturer's instructions. RNA was fragmented to ˜100 nucleotide fragments with Ambion fragmentation reagent (2 mins incubation at 70° C.). The samples were then subjected to Turbo DNase treatment (Ambion), followed by a phenol-chloroform extraction, and resuspension in 85 μl of nuclease-free water, and 5 μl was saved as input. Then, the remaining 80 μl RNA fragments were diluted into IPP buffer (150 mM NaCl, 0.1% NP-40, 10 mM Tris-HCl, pH 7.5). RNA was incubated with 25 μl of protein-G magnetic beads, previously bound to 3 μg of anti-m6A plyclonal antibody (Synaptic Systems), for 3 hours at 4° C. in IPP buffer. Beads were washed twice with 200 μl IPP buffer, twice with 200 μl low-salt buffer (50 mM NaCl, 0.1% NP-40, 10 mM Tris-HCl, pH 7.5) and twice with 200 μl high-salt buffer (500 mM NaCl, 0.1% NP-40, 10 mM Tris-HCl, pH 7.5). Beads were then treated with 300 μl Elution Buffer (5 mM Tris-HCL pH 7.5, 1 mM EDTA pH 8.0, 0.05% SDS, 4.2 μl Proteinase K (20 mg/ml)) for 1.5 hours at 50° C., and RNA was recovered with phenol:chloroform extraction followed by ethanol precipitation. Three human CD34+ umbilical cord blood cells were isolated as described above and isolated total RNA with TRIzol. RNA was fragmented to ˜100 nucleotide fragments with Ambion fragmentation reagent (2 mins 50 secs incubation at 70° C.). The samples were then subjected to Turbo DNase treatment (Ambion), followed by a phenol:chloroform extraction, and resuspension in 18 μl of nuclease-free water, and 1 μl was saved as input. m6A RNA IP was performed with EpiMark® N6-Methyladenosine Enrichment Kit following manufacturer's instructions.


Following m6A preparation of RNA, quality was assessed on Agilent 2100 Bioanalyzer, and 1 ng (mouse) or 10 ng (human) RNA was used to generate RNAseq libraries according to the manufacturer's directions for the SMARTer Stranded Total RNA-Seq Kit—Pico Input Mammalian (Takara Bio Inc) using 16 cycles (mouse) or 13 cycles (human) PCR2 amplification. The method uses random priming and a template switching oligo to generate complimentary DNA, followed by the ligation of barcoded adapters; ribosomal-derived cDNA is then removed through probe-directed enzyme cleavage and subsequent enrichment of un-cleaved fragments.


The protocol was modified to retain lower molecular weight sample fragments by using a 1.2×SPRI bead concentration for PCR1 cleanup. To remove dimerized adapters, libraries underwent 160-600 bp size selection with a Pippin Prep (Sage Science) 2% gel. The resulting libraries were checked for quality and quantity using the Bioanalyzer and Qubit Fluorometer (Life Technologies). Then equal molar libraries were pooled and requantified. For mouse m6A-seq, libraries were sequenced as 50 bp single read on the Illumina HiSeq 2500 instrument using HiSeq Control Software 2.2.58. Following sequencing, Illumina Primary Analysis version RTA 1.18.64 and Secondary Analysis version bcl2fastq2 v2.18 were run to demultiplex reads for all libraries and generate FASTQ files. For human m6A-seq, libraries were sequenced as 75 bp single read on the Illumina NextSeq instrument using NextSeq Control Software 2.1.2. Following sequencing, Illumina Primary Analysis version NextSeq RTA 2.4.11 and Secondary Analysis version bcl2fastq2 v2.18 were run to demultiplex reads for all libraries and generate FASTQ files.


Plasmid construction and stable cell line generation. Mouse Ythdf2 (mYthdf2) was cloned from commercial cDNA clone (ORIGENE #MC200730) into vector pcDNA5/FRT/Flag plasmid using primers listed: mYthdf2 ORF Clone BamhI F: 5′-CGC GGA TCC TCG GCC AGC AGC CTC TTG GA-3′ (SEQ ID NO: 2) and mYthdf2 ORF Clone NotI R: 5′-ATA AGA ATG CGG CCG CCT ATT TCC CAC GAC CTT GAC GT-3′ (SEQ ID NO: 3). Then Flag-mYthdf2 was subcloned under EF1a promoter in pSicoR-EF1a-IRES-EGFP lentiviral construct (Gibson Assembly®, forward primer: 5′-GTC GAC GGT ACC GCG GGC CCA TGG ATT ACA AGG ATG ACG ACG-3′ (SEQ ID NO: 4) and reverse primer: 5′-GAG GGA GAG GGG CGG ATC CCC TAT TTC CCA CGA CCT TGA CGT-3′ (SEQ ID NO: 5)). Human Ythdf2 (hYthdf2) was cloned from plasmid provided by the Chuan He lab using primers indicated: Forward 5′-CGT TCG AAA TGT CGG CCA GCA GCC TCT-3′ (SEQ ID NO: 6); Reverse 5′-TCC CCC GGG TTA TTT CCC ACG ACC TT-3′ (SEQ ID NO: 7). Then hYthdf2 was cloned into pSicoR-EF1a-IRES-EGFP constructs under EF1a promoter by BstBI and XmaI restriction digestions and ligation. To generate Flag-mYthdf2 HPC7 stable cell line, lentiviruses were generated by transfection of pSicoR-EF1a-Flag-mYthdf2-IRES-EGFP constructs together with the psPAX2 and pMD2.G plasmids at a ratio of 10:7.5:2.5 into 293T cells using calcium phosphate transfection. The virus particles were harvested 48, 72, and 96 hours post transfection, filtered by 0.45 micrometers filter unit (Millipore), and then centrifuged at 18,000 RPM, 4° C. for 2 hours. HPC7 cells were infected with recombinant lentivirus-transducing units in the presence of 4 μg/mL polybrene (Sigma). 48 hours after infection, GFP+ cells were sorted and cultured for experiments.


irCLIP-seq and data analysis. For irCLIP-seq, the procedure was modified from the previously reported methods (Zarneger et al. Nature Methods, 13: 489-492, 2016); Simsek et al. Cell, 169: 1051-1065 e1018, 2017). In brief, irCLIP was performed on ˜3×108 Flag-Ythdf2 HPC7 cells by UV crosslinking cells at 0.4 J/cm2 for 3 times. Whole-cell lysates were generated in lysis buffer (150 mM KCI, 10 mM HEPES pH 7.6, 2 mM EDTA, 0.5% NP-40, 0.5 mM DTT, 1:100 protease inhibitor cocktail, 400 U/ml RNase inhibitor; 1 ml cell pellet and 2 ml lysis buffer). Pipetted up and down several times, and then the mRNP lysate was incubated on ice for 5 mins and shock-frozen at −80° C. with liquid nitrogen. The mRNP lysate was thawed on ice and centrifuged at 15,000 g for 15 mins to clear the lysate. Flag-Ythdf2 was isolated with 30 μl of protein-G magnetic beads per 1 ml lysate, previously bound to 2 μg of anti-Flag monoclonal antibody (Sigma) for 2 hours at 4° C. on rotation. The beads were collected, washed eight times with 1 ml ice-cold NT2 buffer (200 mM NaCl, 50 mM HEPES pH 7.6, 2 mM EDTA, 0.05% NP-40, 0.5 mM DTT, 200 U/ml RNase inhibitor) and one time with 200 μl irCLIP NT2 buffer (50 mM Tris, pH 7.5; 150 mM NaCl; 1 mM MgCl2; 0.0005% NP-40). mRNP complex was digested with RNase 1 (Thermo Fisher #AM2294) at 0.4 U/μl in irCLIP NT2 buffer (aqueous volume of 30 μl and supplemented with 6 μl of PEG400 (16.7% final)). The nuclease reaction was incubated at 30° C. for 15 mins in an Eppendorf Thermomixer, 15 s 1,400 r.p.m., 90 s rest. Nuclease digestions were stopped by addition of 0.5 mL of ice-cold high-stringency buffer (20 mM Tris, pH 7.5; 120 mM NaCl; 25 mM KCI; 5 mM EDTA; 1% Trition-X100; 1% Na-deoxycholate). Immunoprecipitates were then quickly rinsed with 0.25 mL then with 0.05 mL of ice-cold irCLIP NT2 buffer. The irCLIP adaptor ligation and library construction followed previously reported protocol (Zarneger et al. Nature Methods, 13: 489-492, 2016).


Data were demultiplexed using FAST-iCLIP version 0.9.3 and aligned to mouse genome mm10 from UCSC using STAR (2.4.2a) with parameters “-outFilterScoreMinOverLread 0 -outFilterMatchNminOverLread 0 -outFilterMatchNmin 0”. RPM-normalized genome browser tracks were created in R (3.4.1) and plotted using the Gviz package (1.20.0). Enriched motifs were identified by taking midpoints of each binding site found in all three replicates, adding 20 bases up and downstream, and running MEME (4.11.1) with parameters “-dna -mod zoops -revcomp -minw 5-maxw 10-nmotifs 10-maxsize 1000000”. After motifs were identified, we ran tomtom (4.11.1) against transfac (1-2017) to identify known binding sites. GO enrichment analysis was performed using a hypergeometric test in R. GO terms were considered enriched if they had a BH-adjusted p-value less than 0.05. Selected terms of interest are shown in the bar plot. Bars in the bar plot indicate percentage of genes in the list being tested having the term divided by the percentage of genes in the genome having the term. Peaks found by FAST-iCLIP in all three replicates were assigned to various features in the genome. Promoters were defined as upstream 150 bases from the TSS. “trans_stop” was defined as upstream and downstream 200 bases from the transcript start site.


Cord blood transduction. Cord blood transduction was conducted as described previously (Rentas, S. et al. Nature, 532:508-511, 2016, doi:10.1038/nature17665). Briefly, fresh CD34+ cord blood cells or flow-sorted CD34+CD38 cells were prestimulated for 12-18 h in StemSpan medium (StemCell Technologies) supplemented with growth factors interleukin 6(IL-6; 20 ng/ml, Peprotech), stem cell factor (SCF; 100 ng/ml, Peprotech), Flt3 ligand (FLT3-L; 100 ng/ml, Peprotech) and thrombopoietin (TPO; 20 ng/ml, Peprotech). Lentiviruses were then added in the same medium at a multiplicity of infection (MOI) of 50-200 for 24 hours. Cells were then given 2 days after transduction before in vitro or in vivo assays. Human YTHDF2 was targeted for knockdown by shRNA targeting 5′-AAGGACGTTCCCAATAGCCAA-3′ (SEQ ID NO: 8) near the N terminus of CDS, as used in a previous report (Wang, X. et al. Nature 505:117-120, 2014, doi:10.1038/nature12730). Scramble shRNA (seed sequence 5′-GCGCGATAGCGCTAATAAT-3′ (SEQ ID NO: 9)) were used as control.


Clonogenic progenitor assays. Flow-sorted GFP+ cord blood cells from day 10 cultured transduced cells (12,000 per ml) were resuspended in semi-solid methylcellulose medium (Methocult H4034; StemCell Technologies). Colony counts were carried out after 14 days of incubation.


Human umbilical cord blood HSPC culture. 2 days after transduction, human cord blood CD34+ or CD34+ CD38 cells were collected and the GFP+ percentage was determined by flow cytometry. To ensure that equal numbers of GFP+ cells were cultured before expansion, identically cultured GFP cells were added to the one with higher GFP+ percentage to match the % GFP+ between control and hYthdf2 KD. Then cells were seeded at a density of 105 per ml in StemSpan medium (StemCell Technologies) supplemented with growth factors IL-6 (20 ng/ml), SCF (100 ng/ml), FLT3-L (100 ng/ml), TPO (20 ng/ml) and CHIR99021 (250 nM) (Stemgent) (Perry et al. Genes and Development, 25: 1928-1942, 2011).


Human HSC xenotransplantation. For human cord blood HSC ex vivo expansion analysis, 105 sorted CD34+ CD38 cells were transduced with human YTHDF2 shRNA or control shRNA for 3 days and then analyzed for transduction efficiency (% GFP−/+) and stem cell markers. On day 10, cultured cells were collected for stem cell marker analysis. For hUBC HSC primary LDA assay, CD34+ cells were enriched as described above and transduced with human YTHDF2 shRNA or control shRNA at 50 MOI. Media were changed at 24 hours post infection. Equal number of GFP+ cells were sorted out from control or YTHDF2 KD cells on 3 days post infection and cultured overnight. Three doses, 50K, 20K and 10K, of sorted GFP+ cells were transplanted into sublethally irradiated (3.25 Gy) NSG mice, respectively. The cut-off for HSC engraftment was an exhibition of more than 1% human CD45+ GFP+ cells out of total CD45+ cells in BM of primary transplantation recipients. For hUCB HSC secondary LDA assay, BM cells from highest two doses primary recipients were collected and mixed together at 10 weeks post transplantation. Three doses, 1.2×107, 8×106, 4×106, of BM cells were transplanted into sublethally irradiated (3.25 Gy) NSG mice, respectively. The cut-off for HSC engraftment was an exhibition of more than 0.2% human CD45+ GFP+ cells out of total CD45+ cells in BM of secondary transplantation recipients. HSC frequency was assessed using ELDA software (Hu et al. Journal of Immunological Methods, 347: 70-78, 2009). For all human cord blood xenotransplantation experiments, female NSG mice aged 6-8 weeks were used.


m6A-seq data analysis. Human and mouse m6A-seq data were aligned to the transcriptome of hg19 and mm10. In order to identify m6A peaks, hg19 and mm10 transcriptome was divided into 25 nucleotide-wide tiles. The number of reads in the m6A IP and non-IP (control) sample was counted in each tile, and p value was calculated with Fisher exact test and adjusted for multiple testing. Tiles with significant m6A signal enrichment (adjust-Pval <=0.05) were merged into bigger regions. Regions smaller than 100 bp were discarded, and regions over 200 bp were divided into 100 to 200 bp sub-regions; m6A signal over control was calculated at each region; and regions with at least 2-fold enrichment in all replicates were identified as m6A peaks. m6A peaks distribution and m6A marked genes were determined by overlapping all m6A peaks with hg19 and mm10 RefGene annotation. m6A marked genes were identified by overlapping m6A peaks with hg19 RefGene. To filter for transcription factors, genes marked by m6A in all three samples were compared against human transcription factor database fantom.gsc.riken.jp/5/sstar/Browse_Transcription_Factors_hg19. GO term analysis was then performed using R package enrich GO. m6A marked human transcription factors were used as searching list, and all the expressed genes were used as background. Hemopoiesis related BP terms with significant enrichment were used to generate FIG. 3C.


RNA-seq. Human cord blood CD34+ cells were transduced with control or human YTHDF2 KD lentivirus and sorted out for GFP+ CD34+ 10 days later. Three replicates of 12,000 GFP+ CD34+ cells were sorted for each group and were used to extract total RNA. Four nanograms of high quality total RNA was used for cDNA synthesis and library preparation according to the manufacturer's directions with the SMART-Seq v4 Ultra Low Input RNA Kit for Sequencing (Takara, 634891) and Nextera XT (Illumina, FC-131-1096). Resulting short fragment libraries were checked for quality and quantity using an Agilent 2100 Bioanalyzer and Invitrogen Qubit Fluorometer. Equal molar libraries were pooled, requantified, and sequenced as 75 base pair single reads on a High Output flow cell on the Illumina NextSeq 500 instrument. Following sequencing, Illumina Primary Analysis version NextSeq RTA 2.4.11 and Secondary Analysis version bcl2fastq2 2.18 were run to demultiplex reads for all libraries and generate FASTQ files.


For RNA-seq analysis, reads were aligned to UCSC genome hg38 with Tophat version 2.0.13 with default parameters, using Ensembl 87 gene models. Read counts were generated using HTSeq-count with -m intersection-nonempty. Reads were also aligned to ERCC control sequences and counts tabulated. A scaling factor was calculated based on the median of the ERCC counts for each sample and used for normalization. Differentially expressed genes were found using the edgeR package (3.18.1) in R (3.4.1). Differentially expressed genes were required to have a BH-adjusted p-value <0.05 and a 2-fold change in expression.


RNA stability assay. 15,000 sorted LT-, ST-HSCs and MPPs were cultured in StemSpan SFEM medium (Stem Cell Technologies) supplemented with 10 μg/mL heparin (Sigma), 0.5× penicillin/streptomycin (Sigma), 10 ng/mL recombinant mouse (rm) SCF (Biovision, Inc.), and 20 ng/mL Tpo (Cell Sciences, Inc.) (Perry et al. Genes and Development, 25: 1928-1942 (2011)) at 37° C. 5% CO2 5% O2. Sorted cells were treated with 5 μM actinomycin D (Sigma) for inhibition of mRNA transcription. Cells were harvested at 0 hour or 4 hours post treatment, and total RNA was extracted and used for RNA-seq.


m6A RNA Methylation Quantification.


Mouse BM Lineage negative cells from wt and Ythdf2 KO mice were enriched with mouse Lineage Cell Depletion Kit (Miltenyi Biotec), followed by total RNA extraction with TRIzol (Invitrogen). The quantification of m6A RNA methylation in Lin cells were performed with m6A RNA Methylation Quantification Kit (Abcam ab185912) following manufacturer's protocol. 200 ng total RNA were used per replicates for either group.


Qpcr Analysis.


105 LSK cells were sorted from wt and Ythdf2 KO mice. Total RNA were extracted with TRIzol (Invitrogen). cDNA synthesis was conducted with High-Capacity RNA-to-cDNA™ Kit (Thermo) following manufacturer's protocol. qPCR primers used are listed in Table S5, qPCR primers used to verify the expressional levels of transcription factors in wt and Ythdf2 KO HSPCs.


Western blot and intracellular staining. To validate the KO or KD efficiency in Ythdf2 KO mouse model or hUCB, 33,000 cKit+ cells or 120,000 GFP+ cells were sorted from BM or transfected hUCB samples, respectively. Hela cells transduced to overexpress human YTHDF2 were used validate overexpression efficiency as shown in FIG. 14B. Immunoblotting was performed with anti-YTHDF2 rabbit polyclonal antibody (MBL, RN123PW) and β-actin mouse monoclonal antibody (NOVUS, NB600-501). Secondary antibodies used were IRDye 8000 W Goat anti-Mouse IgG and IRDye 8000 W Goat anti-Rabbit IgG antibodies (LI-COR). For intracellular staining, BM cells from wt and Ythdf2 KO mice were stained with HSC markers as above, then fixed with the Cytofix/Cytoperm kit (BD Biosciences) according to the manufacturer's instructions. Fixed and permeabilized cells were immunostained with anti YTHDF2 antibody (MBL RN123PW), anti TAL1 antibody (Santacruz sc-393287), anti GATA2 antibody (Santacruz sc-267), anti RUNX1 antibody (Santacruz sc-365644), anti STAT5 antibody (Santacruz sc-74442) and detected by Alexa-488 donkey anti-rabbit IgG antibody (Invitrogen).


Single cell immunostaining. 10,000 LSKs from wt and Ythdf2 KO mice were sorted onto Poly-L-lysine coating slides, which were placed in a moisture chamber and incubated at 4° C. for 30 mins to allow cells settling onto the slides. Cells were fixed with chilled methanol at RT for 10 mins, blocked with universal blocking reagent (BioGenex) at RT for 30 mins, and stained with mouse TAL1 antibody (Santa Cruz, SC393287) or mouse IgG control (Abcam) at 4° C. overnight. Cells were then stained with Alexa Fluor 488 donkey anti-mouse IgG (Thermo Fisher Scientific) at 4° C. for 30 mins. Images were taken on a PerkinElmer Ultraview spinning disk system with Yokagawa CS-X1 disk. All emission was collected onto a C9100-23 Hamamatsu EM-CCD using Velocity software (PerkinElmer). For Z-stacks, the step size was set at 400 nm. Staining intensity per image was quantified by ImageJ program.


FISH in conjugation with fluorescent immunostaining. Sorted LSKs were spun onto microscope glass slide (Fisher Scientific Cat. No. 12-544-4) using a Cytospin™ 4 Cytocentrifuge at 800 rpm for 1 min with medium acceleration (Thermo Scientific, cat. no. A78300003), followed by an immediate immersion into 4% PFA (diluted from 16% (wt/vol) aqueous solution, Electron Microscopy Sciences, cat. no. 15710). Cells were fixed at RT (25±2° C.) for 30 mins. RNA in situ hybridization was performed using RNAscope multiplex fluorescent detection kit according to the manufacturer's instructions (Advanced Cell Diagnostics) with a couple of modifications: Antigen retrieval was unnecessary, and digestion was performed with 1:15 diluted proteinase Ill solution for 10 mins at RT. RNAscope probes targeting mouse Tal1 and Gata2 were designed and produced by ACDbio. After the in situ hybridization was completed, slides were rinsed twice with PBST and directly processed with background blocking (Background buster solution, Innovex, cat. no. NB306) and primary antibody incubation. Anti-YTHDF2 (MBL, 1:500) and anti-Dcp1a (Santa Cruz, SC100706, 1:200) antibodies were diluted with antibody diluent reagent buffer (Life technologies, cat. no. 003118) and incubated at 4° C. overnight. Donkey anti-rabbit Alexa Fluor 488 (Invitrogen, 1:500) and donkey anti-mouse Alexa Fluor 633 (Invitrogen, 1:500) were used for protein target multiplexing.


Example A-1

Ythdf2 KO Leads to Increase in Phenotypic HSCs in Primary Mice.


To investigate the effects of Ythdf2 on phenotypic HSCs, Crispr-Cas9 technology was utilized to generate Ythdf2f/f conditional knockout mice, and then crossed with Mx1-Cre mice to specifically reduce Ythdf2 expression in hematopoietic cells (hereafter Ythdf2 KO mice) (FIG. 1A and B). BM HSPCs showed no discernible difference at the absence of pl:pC (FIG. 7A). Four weeks after pl:pC injections, a significant increase was observed in both frequency and absolute number of long-term HSCs (Lin Sca1+ cKit+ (LSK) CD34 Flk2; LT-HSCs) and short-term HSCs (LSK CD34+ Flk2; ST-HSCs), but not multipotent progenitors (LSK CD34+ Flk2+; MPPs) in Ythdf2 KO mice compared to littermate wild type (wt) mice (FIG. 1C to 1E). It was found that the frequency and absolute cell number of Long Term HSCs (LT-HSCs) and ST-HSCs increased by over 2-fold while MPP exhibited milder response (FIGS. 1C and 1E). Although Ythdf2 KO led to increased BM cellularity, the absolute number of committed progenitors, including common myeloid progenitors (CMPs), granulocyte-macrophage progenitors (GMPs), megakaryocyte-erythrocyte progenitors (MEPs) and common lymphoid progenitors (CLPs), as well as mature lineage cells, erythrocytes, myeloid cells, B cells and T cells, showed no significant difference between Ythdf2 KO and wt mice (FIG. 1F to H). Cell cycle analysis revealed no discernible change of quiescence in HSCs or MPPs after Ythdf2 KO (FIG. 7B). Notably, the percentage of apoptotic cells in Ythdf2 KO LT-, ST-HSCs and MPPs significantly reduced compared to wt controls (FIG. 7C). To further identify any potential HSC defects in Ythdf2 KO mice, the number of HSCs, committed progenitors, and mature lineages in the spleen were examined, and no significant differences were found between wt and Ythdf2 KO mice (FIGS. 7D to 7H). In summary, Ythdf2 KO in primary mice specifically increases HSC numbers with no bias or defects in either progenitor or lineage cells.


Example A-2

Ythdf2 KO Expands Functional HSCs in Mice.


To determine whether Ythdf2 KO expands functional HSCs, a short-term homing assay was initially performed by transplanting 1×106 carboxyfluorescein diacetate succinimidyl ester (CFDA SE)-labelled BM cells from KO mice or their control littermates into lethally irradiated recipient mice, and no significant difference was found in their homing capacity between mutant and wt controls (FIG. 7I). Limited dilution, competitive repopulation unit assay (LDA) was then executed by transplanting 2×105, 7.5×104 or 2.5×104 donor BM cells (CD45.2), together with 2×105 recipient BM cells derived from the ptprc mutant strain (CD45.1), into lethally irradiated recipient mice (FIG. 2A). Consistent with an increased number of phenotypic HSCs in Ythdf2 KO mice, it was found that competitive repopulating units (CRUs) increased 2.2-fold in Ythdf2 KO HSCs compared to controls (FIG. 2B). In the 2×105 group, compared to controls, and a significant increase was observed in the overall repopulation rate from Ythdf2 KO donor cells at 16 weeks post transplantation (FIG. 2C). Moreover, recipients of Ythdf2 KO BM cells, compared to that of controls, exhibited markedly higher frequency and absolute number of donor derived LT-HSCs and ST-HSCs, but not MPPs in BM (FIGS. 2D and 2E). Furthermore, it was found that donor derived committed progenitors and mature lineages in BM from transplantation recipients of mutant and wt cells showed no significant changes (FIGS. 2F and 2G). To determine the long-term repopulation ability of HSCs from Ythdf2 KO mice, the secondary transplantation with BM cells derived from primary recipients was conducted. Notably, it was found that compared to controls, CRUs from Ythdf2 KO cells revealed a 3.5-fold increase (FIG. 2H) and exhibited no signs of leukemia in both BM and spleen at 16 weeks after secondary transplantation (FIGS. 9A to 9F). Furthermore, in FIGS. 2I and 2J, a limiting dilution assay was conducted by transplanting total bone marrow (BM) from WT or Ythdf2 KO mice with 3 different dosages. Four weeks post transplantation, it was observed that the engraftment of donor cells increased in the mice transplanted with 200,000 Ythdf2 KO BM cells, as compared to that with WT BM cells. Furthermore, this increase did not generate lineage bias in the transplantation recipients.


We also investigated the long-term effect of Ythdf2 KO on hematopoiesis under homeostasis condition by examining the stem cells, progenitor cells, and lineages in both BM and spleen at over 5 months post pl:pC injections (FIG. 9A). Although we observed a modest increase in LT-HSCs in BM from Ythdf2 KO mice compared to that of controls (FIG. 9C), there were no discernible differences between Ythdf2 KO and control mice in progenitors and lineage cells from either BM or spleen (FIGS. 9D to 9J). These observations indicate that long-term effect of Ythdf2 KO in vivo neither skews lineage differentiation nor facilitates aberrant proliferation, which is in line with previous reports that Ythdf2 is not required for leukemogenesis. To verify the frequency of functional HSCs in the BM at 5 moths post pl:pC induction, we transplanted 7.5×104 BM cells from wt and Ythdf2 KO mice with competent cells into lethally irradiated recipients. We found that Ythdf2 KO led to significantly higher engraftment in recipients comparing to wt controls, suggesting that Ythdf2 KO has long-term capability on mouse HSC expansion in vivo (FIG. 9K). Taken together, these data reveal that Ythdf2 KO results in specific and significant mouse HSC expansion in vivo without affecting lineage commitment.


Example A-3

Ythdf2 Regulates HSC Self-Renewal Gene Expression by m6A-Mediated mRNA Decay.


To explore the underlying mechanisms of how Ythdf2 KO expands HSCs, mapping was performed of the m6A methylome by methylated RNA immunoprecipitation combined with high-throughput sequencing (MeRIP-seq or m6A-seq) in LT-HSCs, ST-HSCs, and MPPs sorted from adult C57BL/6J mice (Meyer et al. Cell, 149: 1635-1646, 2012; Schwartz et al. Cell, 155: 1409-1421, 2013; Dominissini et al. Nature, 485: 201-206, 2012). m6A peaks were selected by identifying significantly enriched overlapping peaks from two independent replicates. Consistent with previous studies (Meyer et al. Cell, 149: 1635-1646, 2012); Dominissini et al. Nature, 485: 201-206, 2012), it was found that m6A peaks were abundant in mRNA open reading frame (ORF), in 3′ untranslated regions (UTRs), and around the stop codon in all three HSPC populations. Transcripts of moderately expressed genes were more likely to be methylated (FIGS. 10A to 10C). Intriguingly, it was found that m6A modifications were enriched in the mRNAs of transcription factors, such as Gata2, Etv6, Stat5 and Tal1, which have been documented to be critical for HSC self-renewal and stem cell state maintenance (Wang et al. Blood, 113: 4856-5865, 2009; Ebina et al. The EMBO Journal, 34: 694-709, 2015; Orkin et al. Cell, 132: 631-644, 2008: de Pater et al. The Journal of Experimental Medicine, 210: 2843-2850, 2013; Hock et al. Genes and Development, 18: 2336-2341, 2004; Lim et al. The Journal of Clinical Investigation 122: 3705-3717, 2012; Reynaud et al. Blood, 106: 2318-2328, 2005; and Kato et al. The Journal of Experimental Medicine, 202: 169-179, 2005), suggesting the m6A modification could play critical roles in the regulation of HSCs (Table S1, Key transcription factors critical for HSC self-renewal and maintenance are labeled by m6A in HSPCs). Given the accumulating evidence that m6A mRNA methylation regulates stem cell fate determination by facilitating the decay of mRNAs coding for transcription factors and genes in key signaling pathways involved in self-renewal and differentiation (Batista et al. Cell Stem Cell, 15: 707-719, 2014; (Geula et al. Science 347: 1001-1006, 2015; Yoon et al. Cell, 2017; Zhang et al. Nature, 549: 273-276, 2017; Zhao et al. Nature, 542: 475-478, 2017; Li et al. Cancer Cell, 31: 127-141, 2017; Li et al. Nature, 548: 338-342, 2017) the mRNA degradation rates were next measured in LT-, ST-HSCs, and MPPs by monitoring mRNA levels after transcription inhibition with actinomycin D. It was found that degradation rates of methylated mRNAs were significantly faster than unmethylated mRNAs in ST-HSCs, and MPPs (FIG. 10D). As Ythdf2 is a well-recognized m6A “reader” that mediates mRNA decay (Wang et al. Nature, 505: 117-120, 2014), the targets of Ythdf2 were further determined by performing infrared UV-crosslinking immunoprecipitation sequencing (irCLIP-seq) in the mouse multipotent hematopoietic precursor cell line HPC-7 (Pinto do et al. The EMBO Journal, 17: 5744-5756, 1998; Zarnegar et al. Nature Methods, 13: 489-492, 2016) (FIG. 3A; FIGS. 11A to 11C). The results showed that 57.8% of Ythdf2 target mRNAs contained m6A peaks (FIG. 11D). Ythdf2 binding sites were enriched with the conserved m6A motif and exhibited the characteristic of m6A distribution features (FIGS. 3B and 3C). Gene ontology (GO) analysis of Ythdf2 target transcripts revealed enrichment of genes related to hematopoietic or lymphoid organ development, suggesting the involvement of Ythdf2 in the regulation of hematopoiesis (FIG. 3D). Notably, it was found that Ythdf2 bound to transcription factor mRNAs, such as that of Tal1 and Gata2, on sites largely overlapping with m6A peaks (FIG. 3E; FIG. 5E and Table S2, Ythdf2 targeted mRNAs from three irCLIP-seq replicates). Significant change was not observed in the total RNA mass in LSK Flk2 cells from wt and Ythdf2 KO mice. Though m6A modification only constitute 0.1-0.4% of adenosine nucleotide in mammal cells, it was found that Ythdf2 KO led to increased level of m6A content in total RNA from BM Lin cells, suggesting that Ythdf2 specifically regulates the stability of m6A-marked mRNAs (FIGS. 12A and 12B). Consistently, qPCR analysis of total mRNA revealed increased levels of Tal1, Gata2, Runx1 and Stat5a, whose mRNAs have shown to be modified by m6A, in Ythdf2 KO LSK cells compared to wt controls (FIG. 3F). Single cell immunofluorescence staining and intracellular flow cytometry further revealed that Ythdf2 KO HSPCs exhibited significant increases in the intensities of m6A-labeled transcription factors involved in stem cell self-renewal, such as TAL1, GATA2, RUNX1 and STAT5, indicative of a suppressive role of Ythdf2 in HSC self-renewal (FIG. 3G; FIG. 12C). A previous study has shown that Ythdf2 regulates RNA metabolism through localizing the bound mRNAs to mRNA decay sites (Wang et al. Nature, 505: 117-120, 2014). To further explore the mechanism of Ythdf2 in regulating HSC self-renewal, fluorescence in situ hybridization (FISH) was performed of Tal1 mRNA and fluorescence immunostaining of Ythdf2 and Dcp1a, a marker of mRNA decay sites (Sheth et al. Science, 30:805-808, 2003; Kedersha et al. Methods in Enzymology, 431: 61-81, 2007), and their relative spatial distribution was analyzed in sorted wt and Ythdf2 KO HSPCs. Co-localization of Tal1 mRNA, Dcp1a and Ythdf2 was observed in wt cells while substantially reduced in Ythdf2 KO controls (FIGS. 3H and 3I). Furthermore, similar observation was confirmed by co-staining Gata2 mRNA FISH with Ythdf2 and Dcp1a in wt or Ythdf2 KO HSPCs (FIGS. 12D and 12E). To determine whether the increased transcription factors, such as Tal1, expression accounts for the HSC expansion in Ythdf2 KO mice, rescue experiments were performed using short hairpin (sh) RNA-mediated Tal1 knock down (KD) in wt and Ythdf2 KO LSK cells, followed by transplanting into lethally irradiated recipients. Depletion of Tal1 in HSPCs significantly impaired the reconstitution capacity of wt cells as reported previously and also rescued the increased engraftment of Ythdf2 KO cells (FIG. 12F). Overall, these data indicate that Ythdf2 regulates HSC self-renewal by enabling the degradation of mRNAs encoding transcription factors essential for stem-cell renewal.


Example A-4

Dissecting the Role of Ythdf2 in Human UCB HSPCs by m6A-Seq and RNA-Seq.


The limited number of HSCs in a single human umbilical cord blood unit has been an obstacle for clinical applications, such as HSC transplantation (Walasek et al. Annals of the New York Academy of Sciences, 1266: 138-150, 2012). The observation that Ythdf2 KO resulted in an increase of phenotypic and functional mouse HSCs prompted a test whether YTHDF2 knockdown (KD) could facilitate human UCB HSC expansion. First, m6A-seq with CD34+ cells isolated from 3 individual hUCB samples was performed (FIG. 13A). m6A modifications predominantly occurred in mRNAs (˜95%), preferential in mRNA ORF regions, 3′UTRs, and near the stop codon, as expected (˜90%) (FIGS. 4A and 4B; FIG. 13B). m6A landscapes in mouse and hUCB HSPCs were compared, and it was found that 2,239 genes were commonly m6A tagged (FIG. 4C). These commonly m6A-tagged transcripts were enriched for genes related to hematopoiesis and stem cell maintenance (FIG. 4D). Due to the enrichment of m6A labeling in the mRNAs of transcription factors responsible for mouse HSC self-renewal, the m6A-marked transcription factor transcripts in hUCB CD34+ cells were next characterized by performing GO term analysis. Among the 722 identified m6A-labeled transcription factor mRNAs, major GO terms were related to cell fate commitment and stem cell maintenance (FIG. 13C). For example, HOXB4, overexpression of which has been reported to expand human and mouse HSCs ex vivo (Amsellem et al. Nature Medicine, 9: 1423-1427, 2003; Antonchuck et al. Cell, 109: 39-45, 2002), was marked by m6A in hUCB CD34+ cells (FIG. 4E). Other transcription factors required for HSC self-renewal and critical to induce HSCs from other cell types (Ebina et al. The EMBO Journal, 34: 694-709, 2015; Galan-Caridad et al. Cell, 129: 345-357, 2007, such as Zfx, RUNX1 and FOSB, were also m6A-tagged in hUCB CD34+ cells (FIGS. 13F and 13G and see also Supplementary Table S3 of article “Supression of m6A Reader Ythdf2 Prmotd Hematopoeitic Stem Cell Expansion” by Li et al, Cell Research 28, 904-917 (2018), which article (and including the Supplementary Tables thereof) is hereby incorporated by reference herein in its entirety, Genes marked by m6A in human UCB CD34+ HSPCs from individual samples). To further dissect the role of YTHDF2 in hUCB HSPCs, RNA-seq was performed with control or YTHDF2 KD hUCB CD34+ cells (FIG. 4F; FIGS. 13D and 13E). Remarkably, transcripts marked by m6A, including HOXB4 and other HSC self-renewal related transcription factors, showed significant increases of input mRNA reads in the YTHDF2 KD cells compared to the control, without noticeable changes for non-m6A labelled genes (FIGS. 4G to 4I; FIGS. 13F and 13G). These results support the role of YTHDF2 in regulating hUCB HSC self-renewal through RNA degradation.


Example A-5

Expansion of hUCB HSCs by YTHDF2 KD.


To further explore whether suppression of YTHDF2 can expand human HSCs, short hairpin (sh) RNA-induced YTHDF2 KD in hUCB HSPCs was performed as above (FIG. 4F). After 7 days ex vivo culture, lentiviral knockdown of YTHDF2 resulted in an average 14.3-fold and 13.6-fold increase, respectively, in the frequency and absolute number of CD34+ CD38 CD45RA EPCR+ phenotypic HSCs and a 5.1-fold increase in CFUs relative to control cells, especially the most primitive CFU-granulocyte erythrocyte monocyte megakaryocyte (GEMM) colony type and burst forming unit-erythroid (BFU-E), reflecting higher expression level of key transcription factors for hematopoiesis, such as TAL1, in YTHDF2 KD hUCB cells (FIGS. 5A to 5D; FIG. 14A). Interestingly, the apoptotic rate was significantly reduced in YTHDF2 KD hUCB HSPCs compared to control cells, similar to the trend of HSCs in Ythdf2 KO mouse (FIG. 5E). Also, FIG. 5F shows that the Ythdf2 knockdown (KD) HSCs exhibited up to a 10-fold increase compared to control HSCs 10 days post transduction. Next, the effect of overexpression (OE) YTHDF2 on HSPC function was explored. Overexpression of YTHDF2 reduced clonogenic potential of hUCB HSPCs by 2.2 fold, suggesting YTHDF2 negatively regulates HSC maintenance ex vivo (FIGS. 14B and 14C).


To determine whether YTHDF2 KD can expand human HSCs in vivo, LDA was performed by transplanting GFP+ cells sorted from hUCB CD34+ cells infected with control and YTHDF2 shRNA at day 4 post infection (FIG. 6A). At 10 weeks post transplantation, we analyzed BM cells were analyzed from recipient NOD/SCID //2rgnull (NSG) mice and measured the functional HSC frequency after in vivo expansion. Notably, compared to control group, recipients of YTHDF2 KD cells displayed a 9-fold increase in human hematopoietic cell (hCD45+ GFP+) engraftment in BM without changes in the proportions of each lineage (FIGS. 6B and 6CH; FIGS. 15A and 15B). YTHDF2 KD significantly increased the percentage of myeloid, megakaryocyte and erythrocyte in the BM of primary recipients (FIG. 15C). Accordingly, it was found that the HSC frequency in YTHDF2 KD cells was increased 4.4-fold relative to that in control cells (FIG. 6D). It was confirmed the long-term capability of YTHDF2 KD hUCB cells to be reconstituted and undergo self-renewal; 12 weeks after transplantation of BM from primary recipients into sublethally irradiated secondary NSG recipient mice, human hematopoietic cell chimerism in BM were higher in the YTHDF2 KD group, as compared to that in the control group (FIGS. 6E, 6F; FIG. 15D). CRUs from YTHDF2 KD cells revealed an 8-fold increase relative to that in control cells (FIG. 6G). These data demonstrate that YTHDF2 KD remarkably facilitates the expansion of both phenotypic and functional hUCB HSCs ex vivo.


Example A-6

The examples herein demonstrate that conditional deletion of Ythdf2, m6A reader, lead to expansion of phenotypic and functional HSCs without lineage bias. To investigate if there is concomitant increase in mesenchymal stem cells in vivo, Ytdhf2f/f if mice were crossed with Mx1-Cre mice to conditionally delete Ythdf2 expression from mesenchymal cells. Nine-months post pl:pc injection bone marrow cells were isolated from Ythdf2KO and their wild type littermates. Single-cell suspension of total bone marrow cells were immuno-stained with flow antibodies. Hematopoietic (CD45, Ter119) and endothelial cells (CD31) were excluded using specific markers. Mesenchymal stem cell present within the total bone marrow stromal cells were further purified by inclusion of N-Cadherin and CD105 antibodies. Mesenchymal stem cells marking both N-Cadherin+ and CD105+ were quantitated. Conditional deletion of Ythdf2 led to 3.6-fold expansion in frequency of mesenchymal stem cells (FIG. 16). Our study clearly demonstrates that loss of Ythdf2 can expand bone marrow mesenchymal stem cells in vivo.


DISCUSSION

Although recent studies explore the biological functions of mRNA m6A modifications (Zheng et al. Molecular Cell, 49: 18-29, 2013; Zhou et al. Nature, 526: 591-594, 2015; Alarcon et al.

Nature, 518: 560-564, 2015), embodiments herein identify Ythdf2 as an important regulator of human and mouse HSC self-renewal by coupling the post-transcriptional m6A modification to the degradation of mRNAs encoding key transcription factors for self-renewal. Repression of Ythdf2 in mouse HSPCs and hUCB HSCs can lead to increased expression of multiple key TFs critical for self-renewal, thereby facilitating ex vivo expansion of both phenotypic and functional HSCs without noticeable lineage bias and leukemia potential. In addition, stem cell niches, to some extent, may contribute to Ythdf2 suppression-mediated mouse HSC expansion as Mx1-cre can be activated in mesenchyme stromal cells. It would be intriguing to study the function of Ythdf2 on mesenchymal stem cells (MSCs) and how repression of Ythdf2 in both HSCs and MSCs may synergistically expand HSCs in vivo.


Given the broad and complicated impact of m6A writer complex Mettl3 and Mettl14 on mRNA splicing, translation, and pri-miRNA processing (Barbieri et al. Nature, 2017; Alarcon et al. Nature, 519: 482-485, 2015; Liu et al. Nature, 518: 560-564, 2015), Mettl3 or Mettl14 depletion results in distinct outcomes in normal stem cells and leukemia. Recent studies have demonstrated that Mettl3 and Mettl14 play essential roles in leukemia development and leukemia stem cell maintenance (Vu et al. Nature Medicine, 2017; Barbieri et al. Nature, 2017; Weng et al. Cell Stem Cell, 22: 191-205 e199, 2018). In contrast, Ythdf2 is believed to be mainly involved in m6A-mediated mRNA decay (Batista et al. Cell Stem Cell, 15: 707-719, 2014; Yoon et al. Cell, 2017; Zhang et al. Nature, 549: 273-276, 2017; Wang et al. Nature, 505: 117-120, 2014). According to certain embodiments herein, it is believed that manipulating Ythdf2 may extend the half-life of specific m6A-marked mRNAs encoding TFs critical for stem cell self-renewal without affecting other aspects of mRNA processing. The Examples herein show that Ythdf2 depletion in HSCs neither skews the lineage commitment nor induces hematological malignancies, reducing the risk of leukemogenesis with expanded HSCs. Furthermore, stem cell self-renewal is a complexed process comprised of cell division, survival, prevention of differentiation and stemness retention. The observation that Ythdf2-deficient HSCs exhibited lower apoptotic rate indicates embodiments of methods herein also benefit another feature of stem cell self-renewal.


A major limitation in using hUCB HSC transplantation is the insufficient number of HSCs in one hUCB unit. Albeit previous studies have revealed that Dlk1, SR1, Musashi2 and UM171 can expand hUCB HSCs by targeting Notch, AHR signaling or other unknown pathway (Boitano et al. Science, 329: 1345-1348, 2010; Fares et al. Science, 345: 1509-1512, 2014; Rentas et al. Nature, 532: 508-511, 2016; Chou et al. Experimental Hematologyl, 41: 479-490 e474, 2013). Accordingly, embodiments herein provide a novel and potent way to target multiple key TFs critical for HSC self-renewal and to enhance the expansion of HSCs. For example, reducing Ythdf2 level and function during in vitro culture via small chemicals or AAV-mediated KD may allow the Ythdf2 level and function to restore after transplantation in vivo, and thus not affect normal HSC maintenance and function in human patients. Furthermore, in certain embodiments, methods described herein may be combined with other methods to facilitate the expansion of not only human HSCs, but also other stem cells, rendering an approach for stem cell-based therapies.

The following protocols were used in the “B” Examples below.


Animals. C57BL/6-Gt(ROSA)26Sortm1(HBEGF)Awai/J(iDTR), B6.Cg-Gt(ROSA)26Sortm14(CAG-tdTomato)Hze/J(R26RtdT), Tg(Cspg4-DsRed.T1)1Akik/J, Cxcl12tm2.1Sjm/J, KitItm2.1Sjm/J (SCFf/f), Cxcl12tm1.1Sjm/J (CXCL12f/f) mice were obtained from the Jackson Laboratory. N-cad-CreERT, and N-cad-TdT mice were generated by Applied StemCell, Inc. To induce N-cad-CreERT; R26-tdT mouse, tamoxifen (Sigma) was injected intraperitoneally at 2 mg per injection for 3 days. To induce N-cad-CreERT; R26-tdT at embryonic stage, a single dose of 1.5 mg of TMX was injected intraperitoneally (IP) into the E12.5 pregnant dam. Cesarean section was performed at E19.5 and the neonatal mice were transferred to foster mice. To induce N-Cad+ cells ablation in N-cad-CreERT;iDTR mice, DT (Sigma) was injected intraperitoneally every other day at a dose of 50 ng per g body as indicated. 5FU (Sigma-Aldrich) was injected once in the tail vein at 150 μg per g body weight. After 5FU injection, mice were analyzed as described in the text. All mouse strains used in this study had a C57BL/6J genetic background. Animals were randomly included in the experiments according to genotyping results. Animal experiments were conducted in a blinded fashion with respect to the investigator. The numbers of animals used per experiment are stated in the figure legends. All mice used in this study were housed in the animal facility at the Stowers Institute for Medical Research (SIMR) and were handled according to SIMR and National Institutes of Health (NIH) guidelines. All procedures were approved by the Institutional Animal Care and Use Committee (IACUC) of the SIMR.


Flow cytometry. For phenotype analysis, hematopoietic cells were harvested from bone marrow (femur and tibia). Red blood cells were lysed using a 0.16 M ammonium chloride solution. For cell surface phenotyping, a lineage cocktail (Lin, phycoerythrin (PE)-Cy5) was used, including anti-CD3 (145-2C11), anti-CD4 (RM4-5), anti-CD8 (53-6.7), anti-Mac-1 (M1/70), anti-Gr1 (RB6-8C5), anti-B220 (RA3-6B2), anti-IgM (II/41) and anti-TER119 (TER-119) (100 ng antibody cocktail per million bone marrow cells, eBioscience). Monoclonal antibodies to SCA1 (D7, eBioscience), c-KIT (2B8, eBioscience), FLK2 (A2F10, eBioscience), CD34 (RAM34, eBioscience), CD48 (HM48-1, eBioscience), CD150 (TC15-12F12.2, BioLegend) and CD49b (HMa2, Biolegend) (all used as 50 ng per million bone marrow cells) were also used where indicated. For lineage analysis of peripheral blood, monoclonal antibodies to CD45.1 (A20, eBioscience), CD45.2 (104, eBioscience), CD3, B220, Mac-1 and Gr1 were used. 7-aminoactinomycin D (7-AAD) (A1310, Life technologies) was used to exclude dead cells. For stromal niche cell analysis, CD45 (30-F11, eBioscience), CD31 (390, eBioscience), PDGFRα-biotin (APB5, eBioscience), LepR-Bio (R&D), CD51 (clone RM7-V, Biolegend). Samples stained with biotin conjugated antibodies were washed with staining medium, then incubated with streptavidin brilliant violet 421TM (Biolegend, 1:500). Cell sorting and analysis were performed using MoFlo (Dako), InFlux Cell Sorter (BD Biosciences), MACSQuant (Miltenyi Biotec) or CyAn ADP (Dako) instruments. Data analysis was performed using FlowJo software.


Whole-mount sternum HSC immunostaining. Sternal bones were collected and transected with a surgical blade into 3-4 fragments. The fragments were bisected sagittally to expose bone marrow cavity, fixed in 4% PFA. blocked/permeabilized in PBS containing 20% normal goat serum and 0.5% Triton X100, and stained with primary antibodies for 3 days. The tissues were incubated with secondary antibodies for 2 hours (Bruns et al., 2014; Kunisaki et al., 2013). Fluorescence imaging was performed on a spinning-disk confocal microscope (UltraVIEW; PerkinElmer), including an inverted microscope (Axiovert 200 M; Carl Zeiss Microimaging, Jena, Germany), attached to a spinning-disk confocal system (CSU-X1; Yokogawa Corporation of America) and Orca-R2 camera (Hamamatsu) with Volocity acquisition software (PerkinElmer) and a 20×/0.8 Plan-Apochromat objective (Carl Zeiss). Images were collected as a series of optical sections, with a step size of 4 μm. Images were collected in a tile pattern (overlap 10%) sufficient to cover the entire sample. Channels were collected sequentially. (Blue dye) was excited using 405 nm light (50 mW diode laser, OEM) and (red dye) was excited using 561 nm light (50 mW solid state laser, OEM), and each was collected using a multibandpass emission filter with 415 nm-775 nm 580 nm-650 nm bands. (Green dye) was excited using 488 nm light (50 mW solid state laser, OEM) and collected using a multibandpass emission filter of 500 nm-550 nm, and (far red dye) was excited using 640 nm light (50 mW solid state laser, OEM) and collected using a multibandpass emission filter with 455 nm-515 nm and 660 nm-750 nm. Exposure times and laser powers were adjusted to compensate for variations in staining.


Second Harmonic Generation (SHG) imaging was performed immediately following fluorescence imaging. SHG images were collected on a LSM-780 laser scanning confocal microscope (Carl Zeiss) equipped with a QUASAR detection unit, a 10×0.45 Plan-Apochromat objective (Carl Zeiss), and Zen 2012 acquisition software (v8.1.3, Carl Zeiss). Images were collected as a series of optical sections, with a step size of 8 μm and a pixel size (1.32 μm/pixel) an integer multiple of four times the fluorescence pixel size. SHG images were taken with a laser light wavelength of 900 nm and collected at 371-420 nm. As a reference for image alignment, images of Cd150-PE were taken using the 561 nm line of a DPSS laser (Melles Griot) and collected at 566-735 nm concurrently with the SHG images. Images were collected in a tile pattern (no overlap) sufficient to cover the entire sample. Tiles were stitched into a complete 3D image using Zen software.


Images were analyzed using Fiji software (1.51 g National Institutes of Health). To align SHG and fluorescence images, fluorescence images were first background subtracted, and image tiles were stitched into a complete 3D image using the Grid/Collection stitching plugin (reference bioinformatics.oxfordjournals.org/content/25/11/1463.abstract). Given that the transfer of the sample from the fluorescence microscope to the SHG microscope involved a small amount of sample rotation, it was necessary to realign the SHG and fluorescence images in 3 dimensions. Alignment of SHG and fluorescence image sets was carried out using a custom plugin available at research.stowers.org/imagejplugins. Firstly, a minimum of 8 common landmarks were identified by visual inspection of both the SHG and fluorescence data sets. Next the Kabsch algorithm was used to find the best scaled rotation to transform the fluorescence coordinates to the SHG image coordinates. Finally, each 3D voxel in the fluorescence image was transformed to the corresponding SHG position and trilinear interpolation was used the find the SHG intensity at that position to create the realigned composite image.


Image analysis was conducted by researchers unfamiliar with the hypotheses of the study. HSCs were identified by eye. Cells were considered negative for staining if the shape of the cell could not be discerned by eye, or if the shape of the cell formed a dark region in a field of positive signal. Distance measurements to niche components were made using Fiji and Microsoft Excel software. The locations of the HSC and nearest point of each of the three niche components were marked using point ROIs in Fiji and locations were transferred to excel, where distances in 3D were then calculated using the 3D Pythagorean Theorem. To calculate distances for randomly distributed HSCs, random point ROIs were generated using a custom plugin in FIJI in the same images analyzed for observed HSCs. The randomly generated points were considered simulated HSCs if they appeared in a reasonable HSC location (as assessed by the presence of Lin+ cells in the surrounding regions). Niche distance measurements for simulated HSCs were then made in the same manner as for observed HSCs.


The statistical significance of differences in the distribution of distances was assessed by Kolmogorov-Smirnov analysis using Origin software. Statistical significance of changes in percentages of HSCs at 5 μm were assessed using a Student's T test in Microsoft Excel. Changes were considered significant if P<0.05.


Final images shown in figures are maximum projections that have been background subtracted and contrast adjusted for clarity.


Transplantation and Repopulation assay. 100 sorted pHSCs or rHSC cells together with 1.0×105 CD45.1 rescue bone marrow cells were transplanted into lethally irradiated (10 Gy) CD45.1 recipients. 2.0×105 CD45.2 BM cells from N-cad-CreERT;iDTR and control mice together with 2.0×105 CD45.1 rescue bone marrow cells were transplanted into lethally irradiated (10 Gy) CD45.1 recipients. Every 4 weeks post transplantation, peripheral blood was collected from the submandibular vein. Hematopoietic repopulation was measured from donor-derived blood cells (CD45.2).


RNA sequencing and analysis. cDNA was generated from 1000 purified cells using SMARTer Ultra Low Input RNA kit (Clonetech) and library was generated by the Nextera XT DNA Library Preparation Kit (Illumina), followed by sequencing on an Illumina HiSeq2500 for 50 bp single reads. Raw reads were demultiplexed into Fastq format allowing up to one mismatch using Illumina bcl2fastq2 v2.18. Reads were aligned to UCSC genome mm10 with TopHat v2.0.13, default parameters. FPKM values were generated using Cufflinks v2.2.1 with “-u—max-bundle-frags 100000000”. Read counts were generated using HTSeq-count with “-m intersection-nonempty”. Three or four replicates were sequenced for each population. Data are accessible at NCBI GEO: GSE104887


CFU-F assay and in vitro differentiation. Cells were sorted directly into culture at a 96-well plate. The cultures were incubated at 37° C. in a humidified atmosphere with 5% 02 and 10% CO2 for 7-10 days. Colonies were stained by CellTracker™ Green CMFDA (Life technologies) and image was acquired by Celigo Imaging Cytometer (Nexcelom). For in vitro differentiation, clonally expanded Ncad-CreERT driven Tomato+ BM/Bone stromal cells were isolated from CFU-F cultures by digesting with 0.25% Trypsin/EDTA, split into 3 aliquots, and seeded into separate cultures permissive for differentiation: StemPro Osteogenesis kit Gibco A10072-01, Adipogenesis kit A10070-01 and Chondrogenesis differentiation kit A10071-01. The osteoblastic differentiation was assessed by VECTOR Red Alkaline Phosphatase; the adipogenic differentiation was detected by Oil Red O (Sigma); and the chondrogenic differentiation was detected by Toluidine blue (Sigma, 0.1 g T Blue/100 mL distilled water).


Bone Sectioning, Immunostaining and Imaging.


Freshly isolated femurs were fixed in 4% paraformaldehyde overnight, followed by 1 to 3 days decalcification in 10% EDTA. For paraffin section, bone samples were processed with Sakura Tissue Tek VIP 5 Tissue Processor (Sakura America, Torrance, CA), and paraffin sections were cut in 5 μm thickness. Sections were deparaffinized with xylene, followed by Alcian Blue/Hematoxylin/Orange G staining. For frozen section, bone samples were processed with the CryoJane tape-transfer system. Sections were blocked with Power Block™ Universal Blocking Reagent for 30 minutes to 1 hour and then stained overnight with rabbit-anti-Aggrecan (Millipore, 1:300), rabbit-anti-Perilipin (Cell Signaling, 1:300) and goat-anti-Osteopontin (R&D, 1:300). Donkey-anti-goat Alexa Fluor 488 and Donkey-anti-goat Alexa Fluor 647 were used as secondary antibodies (all from Invitrogen, 1:300). Antibodies were diluted with Antibody Diluent Solution (Invitrogen 00-3218). Slides were mounted with FLUORO-GEL (Electron Microscopy Science 1798510), and images were acquired with an Olympus slide scanner.


Femoral groove surgery. Mice were anesthetized with 2.5% isoflurane, and buprenorphine was administered for analgesia. The skin of the right leg was shaved and scrubbed with alcohol and iodine. A small incision was made in the skin, lateral to the knee joint. After sliding the skin medially for visualization, an internal incision was made medial to the patella, extending into the quadriceps muscle and along the patella tendon to release the tissue. The patella was subluxated laterally, and the distal femur was exposed. The subchondral bone was perforated using a microsaw to penetrate the articular cartilage at the knee joint. The extensor mechanism (quadriceps, patella tendon and patella) was returned to its original anatomical location. The internal incision was sutured with absorbable suture, and the skin sutured with non-absorbable suture.


Statistics.


Values are shown as the mean±s.e.m. All statistical analyses were generated using GraphPad Prism 5 (GraphPad Software). Student's t test was used for comparisons between two groups. Statistical significance was defined as p<0.05.


Example B-1

Functionally distinguished reserve and primed HSCs in mouse bone marrow. To explore the reserve HSC (hereafter rHSC(s)) subpopulation, a cell surface marker was adapted, CD49b (Integrin α2), which can distinguish intermediate-term from permanently long-term HSCs (LT-HSCs) (Benveniste et al., 2010; Qian et al., 2015; Wagers and Weissman, 2005; Yang et al., 2005). Intriguingly, it was found a CD48 CD49bsubpopulation which exists only in conventional LT-HSCs (CD34Flk2Lineage Sca-1+c-Kit+ (LSK) cells) but not in short-term HSCs (ST-HSCs; CD34+FLK2LSK) or multipotent progenitor cells (MPPs; CD34+FLK2+LSK). It was proposed that the CD48 CD49b LT-HSCs subpopulation enriches rHSCs and that the CD48CD49b+ LT-HSCs subpopulation enriches primed HSCs (hereafter pHSC(s)) (FIG. 17A) and tested with a repopulation assay. It was found that both rHSCs and pHSCs supported hematopoiesis in lethally irradiated mice for up to 40 weeks after transplantation without significant difference (FIG. 17B), consistent with a previous report (Benveniste et al., 2010). However, transplanted pHSCs had very low efficiency in generating rHSCs (95.4% reduction) as well as ST-HSCs and MPPs (˜78% reduction for both populations) in recipients compared to transplanted rHSCs, suggesting that rHSCs hierarchically precede pHSCs (FIG. 17C). Using the Scl-tTA-induced H2B-GFP label-retaining model, it was found that rHSCs significantly enriched more H2B-GFPhigh cells compared to pHSCs (P=0.0039), indicating that rHSCs have slower cell cycle compared to pHSCs (FIG. 17D). Molecularly, it was found that rHSCs had higher expression of Gadd45 g, Cdkn1c (encoding p57), and Foxo1 that are all involved in maintaining Go phase of HSCs, and lower expression of cell cycle activators such as Myc, Pcna, Ccng2, and Cdk4. There was no difference in Ki67 expression between rHSCs and pHSCs, indicating that Ki67 expression alone is insufficient to distinguish the two HSC subpopulations (FIG. 17E).


Because the functional definition for rHSC is drug-resistance, rHSCs or pHSCs were transplanted into recipient mice and the mice were challenged with 5FU at 4 weeks post transplantation. As shown in FIG. 17F, rHSCs were insensitive to 5FU treatment; however, pHSCs dramatically reduced their reconstitution ability (44% reduction at 20 weeks post transplantation). Taken together, the data indicated that CD48CD49b LT-HSC indeed enriched rHSCs that were resistant to chemotherapeutic treatment, whereas CD48CD49b+ LT-HSC enriched pHSCs that were sensitive to chemotherapy; furthermore, the former gave rise to the latter but not vice versa in the transplantation assay.


The direct consequences of acute 5FU challenge on rHSCs and pHSCs were further analyzed. As shown in FIG. 17G, at 3 days post 5FU, around 92% of pHSCs were eliminated and only rHSCs survived, suggesting that rHSCs must have specifically turned on their DNA repair system to overcome the chemotherapeutic stress. To test this hypothesis, the transcriptome profiling of DNA damage response genes in rHSCs, pHSCs and rHSCs post 5FU treatment was analyzed. It was observed that rHSCs maintained a lower expression of genes involving the DNA damage repair system compared to pHSCs during homeostasis (FIG. 17H), but that most DNA repair pathways, such as DNA mismatch repair (MMR), nucleotide excision repair (NER), base excision repair (BER), and homologous recombination, (HR) were significantly activated in rHSCs under 5FU challenge (FIG. 17I). Furthermore, in parallel, a great number of stress response genes (Rodina et al., 2016), which primarily belong to Hsp90 and Hsp70 family, were also upregulated (1.8±0.17-fold and 1.4±0.1-fold respectively) (FIG. 17J), which partially explained how rHSCs survived and reconstituted the hematopoietic system under chemotherapeutic stress.


Taken together, the coexistence of pHSCs and rHSCs were functionally demonstrated in BM. Even with their quiescent state and active DNA-repairing pathways, pHSCs were still sensitive to chemotherapy, whereas rHSCs activated their DNA damage repair and stress response genes to survive chemotherapeutic stress and give rise to pHSCs; thus, rHSCs play a critical role in supporting hematopoietic regeneration under severe stress.


Example B-2

Drug-Resistant rHSCs Predominantly Localize in the Endosteal Region of Bone Marrow


Whether extrinsic mechanisms from the BM niche contributed to rHSC maintenance during hemostasis and under chemotherapeutic stress was further examined. To this end, whole mount HSC staining was performed, which simultaneously detected the relative distribution of rHSCs and pHSCs to bones (achieved by second-harmonic generation, SHG), megakaryocytes (MKs) or vessels within ˜75 μm thickness bone cavity (FIG. 18A-B). Our quantification data showed that 43.4% rHSCs and 31.0% pHSCs were located within 10 μm distance from vessels, and that 22.6% rHSCs and 24.6% pHSCs were located within 10 μm from MKs (FIG. 18C-D), consistent with previous reports that the bulk of the HSC population resides in perivascular and sinusoid zones (Acar et al., 2015; Bruns et al., 2014; Chen et al., 2016; Zhao et al., 2014). Interestingly, it was noticed that 16.4% rHSCs compared to only 3.69% pHSCs located within 10 μm from the bone surface (FIG. 2E). These data showed that both rHSCs and pHSCs were unbiasedly distributed to vessels and MKs, but that rHSCs were located significantly closer to endosteal bone surface compared to pHSCs (P=0.00182).


To test whether the endosteal region preserved rHSCs during chemotherapeutic stress, the distribution of rHSCs was examined at day 3 post 5FU treatment when pHSCs were eliminated (FIG. 18B). Interestingly, we found that ˜55% of surviving rHSCs were preserved by the endosteal niche upon acute 5FU stress, which is a ˜3.5-fold enrichment compared to homeostasis (FIG. 18E). However, there was no significant difference in frequency of surviving rHSCs observed near vessels or MKs (FIG. 18C-D). Consistently, it was observed that only 4.24% of pHSCs survived acute 5FU stress as shown in FIG. 17G. Next, the dynamic process of BM damage and the subsequent recovery after 5FU stress was studied by examining the BrdU-labeled surviving and proliferation cells. It was noticed that at day 2 post 5FU treatment, there was a large loss of the BrdU-labeled cells, indicating an active apoptosis induced by 5FU. At day 3 post 5FU treatment, it was observed that surviving BrdU+ cells (mostly single cells) were mainly detected adjacent to bone lining cells in the endosteal region (FIG. 24A-D). At day 3.5, it was observed that pairs of BrdU+ cells appeared at the endosteal surface, indicating activation and division of surviving cells. Starting and continuing at days 4 and 5, the number of proliferating cells gradually increased, and these cells were very often detected as clusters close to either vessels or potential adipocyte structures (˜55% at day 4 and ˜65% at day 6) (FIG. 24E-I). This observation suggested that bone surface was the niche where cells post 5FU initially survived. These cells were then activated and gave rise to daughter cells, the latter of which underwent expansion mainly in vessels or adjacent to megakaryocytes (Zhao et al., 2014). It was further confirmed that surviving 5FU-rHSCs were indeed detected often as single cells adjacent to the bone surface, and proliferating HSCs often associated with MKs or near the vessels. Surviving rHSCs (green, CD150+ Lin− CD49b−) at day 3 post 5FU treatment were often detected as single cells adjacent to the bone surface (white, SHG), and proliferating HSCs were often associated with MKs (CD150+ Lin+) or near the vessels (red, CD31+) (FIG. 29).


N-cad+ pre-osteoblastic cells in bone surface have been found resistant, whereas Osx+ osteoblasts have been found to be sensitive to 5FU treatment and N-cad+ stromal cells have been found to give rise to Osx+ osteoblasts during recovery post 5FU treatment (Sugimura et al., 2012). A recent study showed dramatic depletion of LepR+ stromal cells in central marrow due to cell death 1 day following irradiation (Zhou et al., 2017). To track the early changes in vascular and endosteal niches, an apoptotic assay was performed at day 1 post 5FU treatment. It was found that the apoptotic CD31+VE-cadherin+ cells greatly increased 1 day post 5FU (FIG. 18F), consistent with previous reports of disrupted blood vessel structure post 5FU (Dominici et al., 2009; Sugimura et al., 2012). To study the endosteal niche, the N-cad-tdTomato (N-cad-TdT) mouse line was established in which the Tomato+ cells report N-cad expression in both central marrow and bone surface (FIG. 24J). A marked increase of apoptotic N-Cad driven Tomato+ cells in the central marrow was noticed, whereas the Tomato+ cells in endosteal zone remained stable 1 day post 5FU (FIG. 18G). At day 3 post 5FU treatment when hematopoietic regeneration started, N-Cad driven Tomato+ cells in central marrow as well as in bone surface increased by 2.2-fold and 1.7-fold respectively (FIG. 18H, FIG. 24K). The number of CD31+ vessel cells also increased but showed a dilated and damaged architecture (FIG. 18I). Taken together, previous reports and this data showed that vessels and associated stromal cells in the perivascular niche, including LepR+ and N-cad+ cells, suffered immediate damage and were sensitive to 5FU stress, whereas N-cad+ endosteal stromal cells remained stable.


The data partially explain previous findings that most HSCs are predominantly distributed in perivascular and sinusoidal zones (Acar et al., 2015; Chen et al., 2016; Kunisaki et al., 2013). pHSCs which account for 51.3% of the quiescent HSC population are near perivascular and sinusoid zones in homeostasis. Under stress, however, rHSCs reside closer to the bone surface survive chemotherapeutic stress. Collectively, the data indicate that the endosteal niche plays a critical role in protecting rHSCs from chemotherapy.


Example B-3

N-Cad+ Niche Cells Maintain Functional HSCs Including rHSCs in Bone Marrow


Though N-cad+ stromal cells were the first identified HSC niche cells, and though N-cad+ stromal cells at the endosteal niche were resistant while Osx+ osteoblasts were sensitive to chemotherapy, a direct evidence for N-cad+ functionally supporting HSCs was still missing due to lack of proper genetic mouse lines. According to aspects herein, the N-cad-CreERT line was generated (FIG. 25A) and showed that N-cad+ stromal cells gave rise to both Col2.3-GFP+ osteoblastic cells and perivascular cells (FIG. 25B). A previous study showed that depleting the mature Col2.3-GFP+ osteoblasts did not affect overall engraftment of BM cells (Ding et al., 2012; Greenbaum et al., 2013), but only caused impaired regenerative capacity of a subset of LT-HSCs (Bowers et al., 2015). Though N-cad+ stromal cells developmentally proceed Osx+ osteoprogenitor cells, which further give rise to mature Col2.3+ osteoblasts, a functional contribution to HSC maintenance by N-cad+ stromal cells is unknown. To investigate the HSC niche role of N-cad+ cells, N-cad-CreERTinduced DTR (encoding diphtheria toxin receptor) line (N-cad-CreERT;iDTR) was generated, in which N-cad+ niche cells were rendered sensitive to diphtheria toxin (DT). Three tamoxifen (TMX) injections were administered and followed with intraperitoneal injections of DT (one injection every other day) to the N-cad-CreERT;iDTR mice and analyzed them on the first day after the last injection (FIG. 19A). The efficient ablation was observed of N-cad+ stromal cells in N-cad-CreERT;iDTR; R26-tdT compared to N-cad-CreERT; R26-tdT mice treated concurrently with DT (FIG. 19B). Whether N-cad+ cell ablation would affect HSCs in vivo was further examined. After ablating N-cad+ cells, no significant change was observed of cellularity in BM compared to controls (FIG. 19C). However, the numbers of HSCs were dramatically reduced: rHSCs (65.0% reduction), pHSCs (60.0% reduction), ST-HSCs (59.6% reduction), and MPPs (29.3% reduction) (FIG. 19D). This indicated that N-cad+ niche cells contributed to the most primitive, including reserve, HSC maintenance.


A transplantation assay was also performed to test the functional HSC numbers in N-cad+ stromal cell ablated mice. It was found that bone marrow cells from N-cad+ stromal cell ablated mice gave significantly lower levels of donor cell reconstitution (28.3% reduction at 20 weeks) (FIG. 19E) with reduced myeloid cell production (24.5% to 17.1%) (FIG. 19F). To further investigate whether N-cad+ niche cells contributed to maintaining the long-term self-renewal of HSCs, a secondary transplantation was conducted at 20 weeks post the primary transplantation. It was observed that BM cells from the N-cad+ stromal cell ablated mice had deeper reduction of donor cell reconstitution capacity in the secondary transplantation (40.5% reduction at 16 weeks) (FIG. 19G), although they were capable of multilineage reconstitution (FIG. 19H).


Furthermore, we found that conditional knockout of Cxcl12 from N-cad+ stromal cells significantly reduced pHSCs (48% reduction) and ST-HSCs (28.8% reduction), but no significant reduction was observed in rHSCs. There was a slight albeit insignificant increase of MPPs. (FIG. 19I). Conditional deletion of SCF from N-cad+ stromal cells significantly reduced rHSCs (60% reduction), pHSCs (38.6% reduction), and ST-HSCs (53.7% reduction), but with a slight increase in MPPs (FIG. 19J). Overall, we provided the first functional evidence that N-cad+ niche cells contributed to HSC maintenance, including rHSCs, via producing maintenance factors.

Transcriptome Analysis for Hematopoietic Cells and their BM Niche Cells


To understand the molecular mechanisms governing how different niche cells contribute to HSC subpopulation regulation, a transcriptome profiling analysis was performed on 4 types of hematopoietic stem and progenitor cells (HSPCs) during homeostasis and on rHSCs at day 3 post 5FU, as well as on 10 types of BM niche cells. The BM niche cells were harvested from different niche zones of endosteum (B) and central bone marrow (M) (FIG. 26A-B). The pearson distance tree and principal component analysis (PCA) data showed that rHSCs and pHSCs shared a unique transcriptome profiling compared to ST-HSCs and MPPs (FIG. 20A). Interestingly, rHSCs post 5FU treatment appeared to be closer to pHSCs (FIG. 20B), suggesting that surviving rHSCs were primed for activation to support subsequent hematopoietic regeneration post chemotherapy.


It was found that the rHSCs enriched most of the published HSC specific markers, such as Slamf1 (CD150), H19, Ctnnal1 (α-Catulin), Fgd5, vWF, Tek(Tie2), Procr(Epcr), Hoxb5 and Meg3 (or Gtl2) (Acar et al., 2015; Chen et al., 2016; Qian et al., 2015; Sanjuan-Pla et al., 2013; Venkatraman et al., 2013). Particularly, vWF in rHSCs were 6.1-fold higher than in pHSCs, suggesting that rHSCs enriched most of the vWF+ HSCs which reside at the apex of the HSC hierarchy (Sanjuan-Pla et al., 2013). Consistently, progenitor signature genes such as CD34, CD48, and Flt3(Flk2) and Itga2 (CD49b) had low expression in rHSCs (Acar et al., 2015; Chen et al., 2016; Gazit et al., 2014). Interestingly, rHSCs post 5FU had high expression levels of CXCR4, Ctnnal1 (α-Catulin)(Park et al., 2002), Esam (Endothelial cell-selective adhesion molecule) and CD150 (encoding Slamf1, signaling lymphocytic activated molecule), consistent with their functions associated with the converted primed state (FIG. 20E).


In niche cell analysis, it was found the N-cad driven tdTomato (N-cad-TdT) (M) had a very similar transcriptome profile compared to other niche cells with mesenchymal stem cell (MSC) potential such as LepR, Cxcl12-RFP, and Nestin-GFP cells in both pearson distance tree (FIG. 20C) and PCA analysis (FIG. 20D), suggesting that N-cad+ cells might have MSC potential and similar function in regulating HSCs. Interestingly, NG2-RFP cells had a very similar transcriptome profile to Col2.3-GFP+ osteoblasts (FIG. 20C-D). It was also found that NG2-RFP cells were predominantly restricted to endosteum in the epiphysis or diaphysis, though they were also detected in the peri-arterial region (FIG. 26C).


It was found that Pecam (CD31), CDH5 (VE-cadherin) were enriched in Pecam-GFP+ endothelial cells. PF4 and Adgre1 were enriched in MKs and macrophages (Macs). Cspg4 (NG2) was enriched in NG2-RFP cells. Nestin-GFP cells did not have endogenous Nestin (Nes) expression, consistent with previous reports (Ding et al.,2012; Greenbaum et al., 2013). Interestingly, it was found that several marker genes such as KitI (SCF), LepR, Cdh2 (N-cadherin, N-CAD), Cxcl12, Pdgfrα were broadly expressed in perivascular niche cells (FIG. 20F). N-cad-TdT(B) cells isolated from the endosteal zone also had high levels of SCF, Cxcl12, LepR and Pdgfrα expression compared to other cells from the endosteal zone, such as Col2.3-GFP and NG2-RFP cells (FIG. 20F). Our GO term analysis showed that Col2.3-GFP, Pecam-GFP, MK and Mac cells highly enriched RNA metabolism, protein metabolism, other metabolism pathways and translation activities, indicating that these cells were in a relatively active functional state compared to N-cad-TdT cells and other perivascular zone cells which were in a relatively lower metabolic state. Endothelial cells and perivascular cells had immune system process and stress response activities (FIG. 20G). Because N-cad+ cells had transcriptome profiles similar to other MSCs such as LepR+, Cxcl12-RFP, and Nestin-GFP cells, we next analyzed and compared stromal development related genes from different niche cells (FIG. 20H). It was found that Col2.3-GFP cells enriched osteoblast gene Col1a and progenitor cell gene Ly6a (SCA1) (Yang et al., 2014). N-Cad-TdT(B) cells from the endosteal region enriched chondrocyte genes Spock1, Col2a1 and Col1a2 and bone development genes such as Tnc. Interestingly both N-Cad-TdT(B) and N-Cad-TdT(M) enriched most of the mesenchymal stem and progenitor cell (MSPC) genes such as Prrx1, Pdgfr6, Pdgfrα, Sp7, Sox9 and Grem1. Marrow harvested NG2-RFP cells also had higher levels of MSPC gene expression, such as Alcam, Sp7, Mcam, Sox9 and Gli1, but with high level osteoblast and chondrocyte related genes such as Col1a1, Col2a1, and Col1a2. It was also found that among all perivascular niche cells, LepR+ cells exclusively enriched Gla as well as several osteoblast and chondrocyte markers such as Atf4 and Tnc. Cxcl12-RFP cells significantly enriched MSPC gene Itgav. Furthermore, Grem1 was enriched in N-Cad-TdT(B) and in all perivascular niche cells but not in NG2-RFP cells.


Consistent with earlier data, Col2.3-GFP cells were enriched for more mature osteo-lineage genes (Dmp1, Col1a1, Spp1, Bglap). Nestin-GFP, Cxcl12-RFP and LepR were consistent with their known role in enriching MSC genes (Prrx1, Pdgfrα, Itgb1, Grem1 (FIG. 20H). Interestingly, apart from expressing MSC genes, N-Cad-TdT(M) and N-Cad-TdT(B) were enriched for chondrogenic (Sox9, Col2a1 and Tnc), adipogenic (Cebpα, Pparγ, Adipoq) and osteogenic (Col1a1, Runx2) genes, suggesting a tri-potential nature of N-Cad+ stromal cells. Surprisingly, NG2-RFP was enriched for both bone development genes (Dmp1, Bglap, Sp7, Runx2, Col1a1) and chondrogenic genes (Sox9, Col2a1 and Tnc), suggesting an osteo-chondrogenic role (FIG. 26D-E). These data strongly indicated the heterogeneity of the MSPCs in BM.


Example B-5

N-Cad-CreERT Induced Reporter Cells Largely Overlap with LepR+ and Cxcl12+ Stem/Stromal Cells


To confirm the transcriptional analysis, N-cad in vivo lineage tracing was performed using the TdT or ZsG reporter, and found that, at day 3 post induction, N-cad-CreERT lineage traced cells partially overlapped with Cxcl12-RFP and Nestin-GFP cells (FIG. 20I). Moreover, 98.3% and 97.9% N-cad-CreERT derived cells were positive for LepR and Pdgfrα expression respectively (FIG. 20J). This result further supported that N-cad+ stromal cells have MSC potential as suggested by the transcriptome analysis. To analyze the lineage potential of N-cad+ stromal cells, colony-forming unit-fibroblasts (CFU-F) assay was performed to test their proliferating capacity. It was found that the majority of reported niche cells, whether from endosteal zone or from perivascular zone, had one out of fewer than 10 cells with CFU-F activity, apart from Nestin-GFP+ cells, which had only one out of 17.6 cells with CFU-F activity. N-cad+ cells from bone had one cell with CFU-F activity out of 8.79 cells. N-cad-CreERT derived bone cells had 1 in 10.7 cells with CFU-F activity, and N-cad-CreERT derived marrow cells had 1 in 7.37 cells. (FIG. 20K). Most CFU-F colonies maintained tdTomato signals (FIG. 21A-B), suggesting that N-cad+ cells were the main source of MSPCs with CFU-F activity.


Example B-6

N-Cad+ Stromal Cells Give Rise to Osteoblasts, Chondrocytes, and Adipocytes In Vitro and In Vivo


To test the MSC potential of N-cad+ cells, in vitro differentiation assay was performed by splitting cells obtained from individual CFU-F colonies formed by N-cad+ cells into three aliquots and sub-cloned them into cultures permissive for bone, fat, or cartilage cell differentiation. It was found that Tomato+ cells underwent multilineage differentiation, giving rising to Alkaline phosphate-positive osteoblastic cells, Oil-red-O-positive adipocytes, and Aggrecan-stained and Toluidine-blue-positive chondrocytes (FIG. 21C-E).


To characterize in vivo function of N-cad+ stromal cells, the dynamic anatomical distribution of N-cad derived cells was analyzed after one dose of TMX treatment (FIG. 21F, G). Interestingly, detected N-cad derived cells were detected in metaphysis of trabecular as early as 6 hours post TMX, but only very few cells were seen in central marrow, suggesting that a large portion of N-cad+ cells originated from the endosteal region (FIG. 21H). It was also observed that the number of N-cad derived cells increased by 2.2±0.2-fold in trabecular bone region from 1 to 2 weeks post TMX treatment and remained stable afterwards, in cortical bone region, the cell number increased by 2.95±0.2-fold at 2 weeks post TMX, but then declined at 6 weeks post TMX, suggesting that N-cad+ cells in trabecular bone region were more quiescent compared to cortical bone region. Moreover, N-cad derived cells continuously increased in central marrow up to 6 weeks, suggesting that N-cad derived cells might be proliferating and differentiating within this area (FIG. 21I).


Next, an in vivo lineage tracing assay was performed and it was observed that N-cad+ cells generated Col2.3-GFP+ osteoblasts (Dacic et al., 2001) in a time dependent manner (FIG. 22A, FIG. 27A-B). N-cad-derived osteoblasts were detected in the peri-trabecular region as early as 6 hours post TMX induction (FIG. 22B) and in the compact bone region at 14 hours post TMX induction (FIG. 22C). Further analysis showed that at 6 hours post TMX, immature N-cad+ Col2.3 cells (1.1%±0.2%) were 10-times more enriched in trabecular bone region compared to cortical bone region (0.11%±0.04%) (FIG. 22D, E). Consistently, more immature N-cad+Col2.3 cells were enriched in trabecular bone region compared to compact bone region at 24 hours and 2 weeks post TMX induction (FIG. 22F). At 4 weeks post TMX induction, a large portion of Col2.3-GFP cells (72%±6%) were derived from N-cad+ cells (FIG. 22G).


It was further observed that at 4 weeks post TMX injection, N-cad+ stromal cells generated adipocytes in the trabecular bone region, particularly the endosteal cells, (FIG. 22H), and this was further confirmed by BODIPY lipid probe staining (FIG. 22I). Interestingly, the frequency of N-cad+ derived adipocytes increased quickly initially and declined later on, as evidenced by the quantification that 39.3%±4.5%, 77.1%±6.7% and 17.2%±3% of N-cad+ derived cells were observed at 6, 14 and 24 hours respectively after TMX induction, suggesting that adipocytes might have a frequent turnover rate (FIG. 22J-K, FIG. 27C-E). Collectively, the data demonstrated that N-cad+ stromal cells generated both osteoblast and adipocyte lineages in vivo during homeostasis in adult mice.


Furthermore, it was found that Ncad+ MSCs were enriched >10-fold as compared to other markers. For example, as shown in FIG. 30, just 10K Ncad+ hMSCs produced even higher human thrombopoietin (THPO or TPO) than total hMSCs in vivo. Similarly, Ncad− hMSCs exhibited a function similar to the total hMSCs. Accordingly, isolating MSC with N-cadherin antibodies can provide for enrichment of the MSC population.


Example B-7

N-Cad+ Stromal Cells Give Rise to Chondrocytes During Development and Post Injury


Chondrogenesis is active in fetal development and rarely active in adulthood (Raghunath et al., 2005; Sophia Fox et al., 2009). In mice with TMX induction at postnatal day 2 (P2), no Tomato expression was detected among Aggrecan+ chondrocytes in the femur of N-cad-CreERT; R26-tdT mice (FIG. 28A) despite Tomato+ osteoblasts and perichondrocytes being adjacent to the growth plate. After N-cad-CreERT; R26-tdT mice were induced with TMX at 1 or 2 weeks when the growth plate develops, Tomato+ chondrocytes in cartilages of femur or tibia remained undetectable (data not shown). TMX induction was started to N-cad-CreERT; R26-tdT mice at embryonic stage E12.5, when MSCs were undergoing condensation and chondrocyte differentiation in the fetal bone (FIG. 23A). It was found that the majority of undifferentiated N-cad derived tdT+ cells were located peripherally, with differentiated N-cad derived Tomato+ chondrocytes located in the central region of the rib at E14.5 embryos (FIG. 23B). Importantly, in the trabecular region of femur at P2, N-cad derived chondrocytes were detected in both the columnar zone where the secondary ossification center forms, and in the superficial zone, which is imperative to resist the sheer force for deeper layer protection (FIG. 23C, D). Consistently, N-cad derived adipocytes were detected at 2 months and up until 10 months after birth (FIG. 23E, FIG. 28B), suggesting that N-cad+ cells contributed to early and long-term adipogenesis during development. However, N-cad+ cells derived Osteopontin+ osteoblast and osteocyte were detected at 2 months after birth but not at early P2 (FIG. 23F, FIG. 28C). These data demonstrated that embryonic N-cad-derived cells gave rise to all three osteo-adipogenic-chondrogenic lineages, and only N-cad+ at embryonic stage could efficiently form chondrocytes.


Whether N-cad+ cell could generate chondrocytes in adult mice post injury was next investigated. Cartilage perforation was performed in N-cad-CreERT; R26-tdT mice that received TMX induction at E12.5 (FIG. 23G). At 2 to 3 weeks post cartilage damage, we found that N-cad derived chondrocytes were clustered in the callus at the damage site with a 2-fold increase compared to undamaged control mice (FIG. 23H-1). The femorotibial joint was swollen due to articular cartilage damage in mice post-surgery (FIG. 28D). Alcian blue positive cells with a typical chondrocyte feature were dramatically increased in the post injury region (FIG. 23J), indicating that N-cad+ MSCs quickly regenerated chondrocytes in response to injury.


Taken together, the data proved that N-cad-derived cells induced at the fetal stage (E12.5) could give rise to chondrocyte progenitor in adults and support chondrocyte regeneration in response to injury.


Discussion

rHSCs vs. pHSCs


The heterogeneity of HSCs has been widely studied. HSCs can be maintained in either active, quiescent or deeply quiescent states. It is well known that the quiescence characterization of HSCs is functionally related to their long-term self-renewal potential (Foudi et al., 2008; Wilson et al., 2008). However, how the quiescent HSC population overcomes the consequence of myeloablation in vivo is an unanswered question. In spite of their quiescence, the majority of HSCs cannot survive chemotherapeutic stress such as 5FU (Longley et al., 2003). According to aspects herein, it was found that a small portion of the HSC subpopulation could survive 5FU treatment in primary mice and were resistant to 5FU treatment in transplantation model. Thus, this HSC subpopulation is defined as rHSCs, while other quiescent but chemotherapeutic sensitive HSC subpopulations are defined as pHSCs (Li and Clevers, 2010). Although both HSC subpopulations supported long-term hematopoiesis in transplantation experiments, pHSCs rarely gave rise to rHSCs, whereas the latter were able to give rise to pHSCs. Mechanistically, it was found that rHSCs have an attenuated DNA repair system compared to pHSCs during homeostasis, but rHSCs can quickly activate their DNA repair pathways and the stress-response program to survive chemotherapeutic stress, and support subsequent hematopoiesis to overcome the consequence of myeloablation.


Niche Matters in Term of Conferring Resistance to Chemotherapy


To explore an extrinsic mechanism underlying the chemo-resistance of rHSCs, an idea was tested that they were preserved in a specific microenvironment in BM. Using whole mount HSC staining (Kunisaki et al., 2013), it was first observed that the bulk of HSCs were associated with vessels and MKs as previously reported. However, it was surprisingly found that the rHSCs were predominantly associated with the endosteal niche compared to pHSCs during homeostasis and post 5FU treatment. This indicated that the endosteal niche could form a distinct BM microenvironment to protect rHSCs from chemotherapeutic stress. Consistently, upon chemotherapeutic stress, most rHSCs were protected in the endosteal niche that enriches chemo-resistant N-cad+ stromal cells, whereas the vessel and perivascular cells were sensitive to 5FU treatment, accounting for a large loss of pHSCs induced by chemotherapy. The whole mount HSC staining was done in sternum which has abundant bone branches and extensions inside the marrow. This feature makes it very similar to the trabecular bone region in the femur. The transplantation assay showing that depletion of N-cad+ niche cells affected HSC maintenance, including rHSCs, supports this notion. HSC quiescence also correlated with their low metabolic state, which may be considered analogous to ‘sleeping’, and was termed as HSC dormancy or hibernation (Takubo et al., 2013; Wilson et al., 2008; Yamazaki et al., 2011). However, it was further showed according to aspects herein that quiescence was not the only mechanism underlying drug resistance; instead, both the intrinsic stress-response program and the extrinsic niche protection contributed to drug resistance.


Identity and Function of N-Cad Stromal Cell in HSC Maintenance in the BM Niche


N-cad+ stromal cells were the first identified HSC niche cells (Zhang et al., 2003) and confirmed by subsequent studies (Arai et al., 2004; Sugiyama et al., 2006). N-cad+ cells were initially proposed as osteoblastic progenitor cells based on their endosteal location. According to apects herein, by using two reporter lines, it was found that N-cad+ stromal cells were distributed in both endosteal region and perivascular sites. More intriguingly, it was found that the majority of N-cad+ cells overlapped with LepR+ cells and Pdgfrα+ cells. Transcriptional analysis showed that N-cad+ cells, LepR+ cells, Cxcl12-RFP (CAR) cells and Nestin-GFP cells had a very similar gene expression pattern. The data strongly indicated that the long-standing controversy of HSC niche concepts might very likely be due to different cell markers being used rather than to their cellular identities.


To determine the identity of N-Cad+ stromal cells, their regional distribution was visualized relative to other known niche cells in the bone marrow using different niche reporter mice. N-Cad+ stromal cells generated 72%±6% Col2.3-GFP+ cells; however, 9.3%±4.7% N-cad+Col2.3GFP cells were also detected in the endosteal region. These immature cells accounted for the primitive MSCs, which could explain the insufficient efficiency of Col2.3-Cre genetic model in HSC niche function studies (Ding and Morrison, 2013; Ding et al., 2012; Greenbaum et al., 2013). Though both N-Cad-TdT+ and Nestin-GFP+ were enriched in the trabecular region, N-Cad-TdT+ was concentrated in the trabecular region where engraftment of transplanted HSCs was detected as previously reported (Nilsson et al., 2001; Xie et al., 2009) and survived after stress as observed here. All these data indicated that although N-cad+ cells share a similar transcriptome profile with other MSCs, their anatomic distribution may indicate their unique HSC niche function; indeed, it was shown that the N-cad+ endosteal niche cell plays a critical role in preserving rHSCs.


By using an inducible DTR system, it was found that ablation of N-cad+ cells eliminated both pHSCs and rHSCs in BM. This could be explained by the anatomical distribution of N-cad+ niche cell in both endosteal and perivascular zones. Furthermore, it was shown that N-cad expression could be detected in a subset of HSCs; however, the N-cad-TdT reporter mouse lines did not support this observation (data not shown). This could be partially explained by the inconsistency between their protein and transcription levels, because another mouse line of N-cad-mCherry (fusion at protein level) indeed had a small subset of HSCs (CD49bCD34Flt2LSK) showing a low level of N-cad expression (primary observation). The functional transplantation data showed that ablation of N-cad+ niche cells resulted in the reduced HSCs including rHSCs. By deletion of Cxcl12 and SCF from N-cad+ cells, it was found N-cad+ stromal cells contributed to HSC maintenance and regulation by producing these two factors. Overall, aspects herein demonstrate that N-cad+ stromal cells function as MSCs and support primitive HSC maintenance, especially under stress.


Transplantation of hematopoietic stem cells (HSCs) from human umbilical cord blood (hUCB) holds great promise for treating a broad spectrum of hematological disorders including cancer, but the limited number of HSCs in a single hUCB unit can restrict its widespread use. Although extensive efforts have developed multiple methods for ex vivo expansion of human HSCs by targeting single molecules or pathways, it has been unknown whether simultaneously manipulating a large number of targets essential for stem cell self-renewal could be achievable. Recent studies have emerged that N6-methyladenosine (m6A) modulates expression of a group of mRNAs critical for stem cell fate determination by influencing their stability. Among several m6A readers, Ythdf2 is well recognized to promote the targeted mRNA decay. However, the physiological functions of Ythdf2 on adult stem cells are still elusive. Embodiments herein demonstrate that conditional knockout (KO) mouse Ythdf2 increased phenotypic and functional HSC numbers, but neither skewed lineage differentiation nor led to hematopoietic malignancies. Furthermore, knockdown (KD) of human YTHDF2 led to over 10-fold increase in ex vivo expansion of hUCB HSCs, 5-fold increase in colony-forming units (CFUs), and more than 8-fold increase in functional hUCB HSCs in the 2 rounds of limiting dilution transplantation assay. Mechanistically, m6A mapping of RNAs from mouse hematopoietic stem and progenitor cells (HSPCs) as well as from hUCB HSCs revealed m6A enrichment on mRNAs encoding transcription factors critical for stem cell self-renewal. These m6A-marked mRNAs were recognized by Ythdf2 and underwent mRNA decay. In Ythdf2 KO HSPCs and YTHDF2 KD hUCB HSCs, these mRNAs were stabilized, leading to an increase in protein levels and facilitating HSC expansion which can be rescued by knockdown the mRNA, such as Tal1 mRNA. Therefore, embodiments show the function of Ythdf2 in adult stem cells maintenance and identify an important role of Ythdf2 in regulating HSC ex vivo expansion via the mechanism of controlling the stability of multiple mRNAs critical for HSC self-renewal, thus having a strong potential for future clinical applications.


Furthermore, regulation of hematopoietic stem cells (HSCs) by the bone marrow (BM) niches has been substantially studied, however, whether and how HSC subpopulations are distinctively regulated by different BM niches remain largely unclear. Here, reserve HSCs (rHSCs) have been functionally distinguished from primed HSCs (pHSCs) and their respective BM niches have been further examined. It has been found that both pHSCs and rHSCs could support long-term hematopoiesis under homeostasis; however, pHSCs were sensitive to chemotherapy, whereas rHSCs survived chemotherapy and supported subsequent regeneration after myeloablation. The whole-mount HSC distribution study revealed that rHSCs were preferentially maintained in the endosteal region that enriches N-cadherin+ bone-lining cells during homeostasis and post-chemotherapy. pHSCs were predominantly associated with blood vessels which were vulnerable to chemotherapy compared to bone. Transcriptome profiling and in vivo lineage tracing results showed N-cadherin+ stromal cells to be functional mesenchymal stem cells, which gave rise to osteoblasts, adipocytes, and chondrocytes during development and regeneration. Finally, it was demonstrated that ablation of N-cadherin+ niche cells or deletion of either Scf or Cxcl12 from N-cadherin+ niche cells affected HSC number and maintenance.


Example C

Expansion of CAR-T Cells Using shRNA


The effect of manipulating Ythdf2 on the expansion of CAR-T cells is being assessed using lentivirus driven human Ythdf2 shRNAs. Successful cloning of YTHDF2 shRNA in a CAR-T lentivector has occurred. The lentivirus has been used to infect human CAR-T cells, and the expansion of the human CAR-T cells is in progress. The expansion is expected to take days to weeks for results. It is believed that significantly enhanced expansion will be demonstrated in the lentivirus-infected CAR-T cell population as compared to a CAR-T control population.
