The use of human stem cells for clinical purposes has become a subject of increasing interest in recent years. This interest has only intensified in the wake of the more recent discoveries that human somatic cells can be induced to form pluripotent stem cells when certain transcription factors are overexpressed. Human induced pluripotent stem cells (hiPSCs) can be generated in a variety of ways, such as reprogramming somatic cells by the expression of four transcription factors. The hiPSCs exhibit similar properties to human embryonic stem cells (hESCs), including the ability to self-renew and differentiate into all three embryonic germ layers: ectoderm, endoderm, or mesoderm. Additionally, hiPSCs overcome ethical concerns, relative to generating hESCs from human embryos, because no embryonic cells are needed to form hiPSCs. Human iPSCs can be induced into any cell type and, since they can be maintained over many passages, they can serve as an almost unlimited source to generate cells from any given person. These properties make iPSC-derived cells a valuable product for cell therapies and toxicology or pharmaceutical high throughput screens. However, therapeutic and commercial uses of iPSC-derived cell products are hampered by low quantities and cell culture impurity due to limitations with current methods for producing and maintaining these cells.
Described herein are cells, cell culture methods, and cell culture media compositions useful for producing and maintaining iPSC-derived cell lines that are of higher purity and maintain cell type integrity better than current iPSC-derived cell lines. Also disclosed are methods of using the described cells and media.
One aspect of the present disclosure is an iPSC-derived mesodermal precursor cell (MPC) line, positive for CD34 and CD31 expression, that may be used to produce at least four different cell types. When cultured under appropriate conditions, these mesodermal precursor cells can be used to produce hematopoietic stem cells (HSC), mesenchymal stem cells (MSC), smooth muscle cells (SMC), or unlimited functional endothelial cells (UFEC). One characteristic that makes the mesodermal precursor cells described herein desirable is that these cells can be maintained in culture for a number of days, or passages, without changing phenotype through differentiation.
The HSCs described herein can be produced by culturing the described MPCs in medium and under conditions known to cause cells to differentiate into HSCs. The described HSCs may be characterized by the expression of CD34, CD31, and CD45. Another characteristic of the described HSCs is that they have the ability to reconstitute the hematopoietic system of an irradiated subject, such as a mouse. The described HSCs also have the ability to maintain their phenotype for extended periods without differentiating, when maintained under appropriate conditions.
The described MPCs are also capable of giving rise to UFECs when cultured under conditions known to allow for differentiation into cells of an endothelial lineage. The described UFECs can be characterized by the expression of CD31, vWF, and CD144. In addition, these cells can mediate the uptake of acetylated low density lipoproteins (LDL). Furthermore, the UFECs produced using the methods and cells described herein have the ability to form vascular-like structures in vitro, a hallmark of endothelial cell progenitors.
Another cell type capable of being produced by the MPCs described herein are MSCs. The MSCs described herein can be characterized by the expression of CD90, CD73, and CD105 in the absence of CD31 and CD45. These cells can also differentiate in vivo or in vitro into a number of different cell types, including adipocytes, osteoblasts, myocytes, or chondrocytes, when cultured under conditions known to cause progenitor cells to differentiate into the respective cell type. The described MSCs also have the ability to maintain their phenotype for extended periods without differentiating, when maintained under appropriate conditions.
The described MPCs may also be used to generate smooth muscle cells according to the methods described herein. For example, the described MPCs can differentiate into smooth muscle cells when cultured under conditions known to cause progenitor cells to differentiate into SMCs. The described SMCs are characterized by the expression of α-SMA, calponin, and SM22. The described SMCs also have the ability to maintain their phenotype for extended periods without differentiating, when maintained under appropriate conditions.
In some embodiments the cell types described herein may be generated using the cells of a subject to produce autologous cells using the cell production methods described herein. The differentiated autologous cells can then be administered to the subject for therapeutic purposes.
Described herein are various tissue culture media that may be used to produce the cells characterized in the present disclosure. In some embodiments the medium formulation includes a mixture of Iscove's modified Dulbecco's medium (IMDM), Ham's F-12 Nutrient Mix, with L-alanyl-L-glutamine additive, albumin, α-monothioglycerol, protein-free hybridoma mixture II, L-ascorbic acid 2-phosphate, L-alanyl-L-glutamine, antibiotic, cholesterol lipids, insulin-transferrin-selenium-ethanolamine supplement, bone morphogenic protein 4, vascular endothelial growth factor, and basic fibroblast growth factor. In some embodiments the medium formulation includes a mixture of Iscove's modified Dulbecco's medium (IMDM), Ham's F-12 Nutrient Mix, with L-alanyl-L-glutamine additive, albumin, α-monothioglycerol, protein-free hybridoma mixture II, L-ascorbic acid 2-phosphate, L-alanyl-L-glutamine, antibiotic, insulin-transferrin-selenium-ethanolamine supplement, bone morphogenic protein 4, vascular endothelial growth factor, and basic fibroblast growth factor. Where the described components are, or include, proteins, such as albumin, bone morphogenic protein 4, vascular endothelial growth factor, or basic fibroblast growth factor, the additive may have an amino acid sequence corresponding to the human form of the protein. The media described herein may further include additives such as stem cell factor, Flt-3 ligand, or thrombopoietin, any of which may be derived from, or correspond to, the human form of the protein. While any of the media additives described herein may be derived from, or correspond to, the human form, this is not necessarily required and additives that are derived from, or correspond to, those of other mammals may also be acceptable.
The cells, media, methods of producing the described cells, and related methods of use are more fully discussed herein.
Described herein are cells, cell culture methods, and cell culture media compositions useful for producing and maintaining iPSC-derived cell lines that are of higher purity and maintain cell type integrity better than current iPSC-derived cell lines.

Various terms relating to aspects of the description are used throughout the specification and claims. Such terms are to be given their ordinary meaning in the art unless otherwise indicated. Other specifically defined terms are to be construed in a manner consistent with the definitions provided herein.
As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the content clearly dictates otherwise. Thus, for example, reference to “a cell” includes a combination of two or more cells, and the like.
The term “about” as used herein when referring to a measurable value such as an amount, a temporal duration, and the like, is meant to encompass variations of up to ±10% from the specified value, as such variations are appropriate to perform the disclosed methods. Unless otherwise indicated, all numbers expressing quantities of ingredients, properties such as molecular weight, reaction conditions, and so forth used in the specification and claims are to be understood as being modified in all instances by the term “about.” Accordingly, unless indicated to the contrary, the numerical parameters set forth in the following specification and attached claims are approximations that may vary depending upon the desired properties sought to be obtained by the present invention. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should at least be construed in light of the number of reported significant digits and by applying ordinary rounding techniques.
Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the invention are approximations, the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical values, however, inherently contain certain errors necessarily resulting from the standard deviation found in their respective testing measurements.
The terms “treating,” “treatment,” and “therapy” refer to any success or indicia of success in the attenuation or amelioration of an injury, pathology or condition, including any objective or subjective parameter such as abatement, remission, diminishing of symptoms or making the condition more tolerable to the patient, slowing in the rate of degeneration or decline, making the final point of degeneration less debilitating, improving a subject's physical or mental well-being, or prolonging the length of survival. The treatment may be assessed by objective or subjective parameters; including the results of a physical examination, neurological examination, or psychiatric evaluations.
The term “subject” refers to human and non-human animals, including all vertebrates, e.g., mammals and non-mammals, such as non-human primates, mice, rabbits, sheep, dogs, cats, horses, cows, chickens, amphibians, and reptiles. In many embodiments of the described methods, the subject is a human.
The terms “induced pluripotent stem cell,” “iPSC,” and variants thereof (e.g., hiPSC) refer to pluripotent stem cells made recombinantly from a somatic cell by expressing certain transcription factors in the somatic cell, such that it becomes pluripotent. The transcription factors expressed in the somatic cell to induce this change are well known in the art; therefore, these terms are not limited to the particular embodiments of such cells described herein. Nor is the scope of these terms limited by the method used to overexpress these factors, be it transduction, transformation, or another means of exogenous gene expression.
The terms “MDM2” and “MDM+” are used interchangeably through this and previous applications.

Mesenchymal Stem Cells (MSC)
Provided herein is a method for producing a mesenchymal stem cell from the mesodermal precursor cell described herein, wherein the method involves first producing a mesodermal precursor cell from an iPSC, as described by the related methods provided herein, and then incubating the mesodermal precursor cell under conditions known to promote differentiation of precursor cells into mesenchymal stem cells.

In some embodiments of the method, the mesodermal precursor cells cultured to give rise to the mesenchymal stem cells are purified, for example by flow cytometry, prior to being further cultured to differentiate into mesenchymal stem cells. Alternatively, in some embodiments of the method, the mesodermal precursor cells cultured to give rise to the mesenchymal stem cells are not purified from other cells in the initial iPSC culture prior to being further cultured to differentiate into mesenchymal stem cells. The described iMSCs may be further characterized by their multipotency. For example the described iMSCs may further differentiate into adipocytes, osteoblasts, myocytes, or chondrocytes in vitro, when cultured under proper conditions known in the art, or in vivo, for example following transplantation.

Furthermore, the iSMCs exhibit the formation of spindles when grown in culture for an amount of time adequate to allow for cell expansion to levels sufficient to allow for spindle formation. In some embodiments of the method, the mesodermal precursor cells cultured to give rise to the smooth muscle cells are purified, for example by flow cytometry, prior to being further cultured to differentiate into smooth muscle cells. Alternatively, in some embodiments of the method, the mesodermal precursor cells cultured to give rise to the smooth muscle cells are not purified from other cells in the initial iPSC culture prior to being further cultured to differentiate into smooth muscle cells.
Unlimited Functional Endothelial Cells (UFEC)
Provided herein is a method for producing unlimited functional endothelial cells (UFECs) (also referred to as “iECs”) from the mesodermal precursor cells described herein, wherein the method involves first producing a mesodermal precursor cell from an iPSC, as described by the related methods provided herein, and then incubating the mesodermal precursor cell under conditions known to promote differentiation of precursor cells into unlimited functional endothelial cells.

In some embodiments of the method, the mesodermal precursor cells cultured to give rise to the unlimited functional endothelial cells are purified, for example by flow cytometry, prior to being further cultured to differentiate into unlimited functional endothelial cells. Alternatively, in some embodiments of the method, the mesodermal precursor cells cultured to give rise to the unlimited functional endothelial cells are not purified from other cells in the initial iPSC culture prior to being further cultured to differentiate into unlimited functional endothelial cells.
Cells for Carrying Out the Described Cell Production Methods
The cell production methods described herein may be carried out using a variety of cell types to give rise to the initial iPSCs that serve as the starting point for these methods and cells. For example, it may be desirable to obtain cells from a subject in need of a cell transplant, stem cell therapy, of precursor cell therapy, and use the subject's own autologous cells, such as fibroblasts for example, to generate autologous iPSCs that may be cultured to give rise to an autologous form of one or more of the cell types described herein. In other embodiments, heterologous cells may be used for producing the cells described herein, even though these cells may be intended for therapeutic use in a subject. In still another embodiment, the methods described herein can be carried out using iPSCs without regard to origin. For instance, the iPSCs could be human cells, primate cells, or other mammalian cells converted to iPSCs by conventional methods.
Cells Produced by the Described Methods
Described herein are a variety of cells capable of being produced by the methods described herein. These cells include iPSC-derived mesodermal precursor cells (MPC), positive for CD34 and CD31 expression that may be used to produce at least four different cell types. When cultured under appropriate conditions, the MPCs can be used to produce hematopoietic stem cells, mesenchymal stem cells, smooth muscle cells, or unlimited functional endothelial cells. One characteristic that makes the mesodermal precursor cells described herein desirable is that these cells can be maintained in culture for a number of days, or passages, without changing phenotype through differentiation. In some embodiments the described MPCs can maintain their phenotype in culture for at least 3 days. In some embodiments the described MPCs can maintain their phenotype in culture for at least 5 days.

Multiple human induced pluripotent stem cells (hiPSCs) were successfully generated from human umbilical vein endothelial cells (HUVECs) and fibroblasts by mediated expression of four transcription factors (Oct4, Sox2, klf4, and c-MYC). Those cells were continually cultured and propagated in a feeder free environment under chemically defined conditions. The hiPSCs maintained normal karyotype, and exhibited similar properties to human embryonic stem cells (hESCs) including self-renewing and differentiation into all three embryonic germ layers (
Studies were conducted to assess the impact of certain defined media on more than 10 hiPSC lines derived from both human umbilical vein endothelial cells (HUVECs) and fibroblasts. The gene expression profile of differentiation cells was analyzed by FACS and biologic function assays. Over a 12-day period of culturing hiPSCs in MDM (as set forth in Table 2) the cells were observed to be prone to commitment to the mesoderm lineage (
In order to assess the differentiation potential of mesoderm precursors (CD31/CD34+ cells) produced from hiPSCs, the cells were incubated under culture conditions known to induce endothelial cell formation by precursor cells. Various culture conditions induced the MPCs to develop into: unlimited functional endothelium (iUFECs), mesenchymal stem cells (iMSC), smooth muscle cells (iSMCs), and hematopoietic stem cells (iHSCs).
The mesoderm precursors were cultured under conditions promoting endothelial cell propagation and maturation, standard culture conditions (37° C. incubation at 5% CO2) using EGM™ 2 medium (Lanza). The cells expanded rapidly with typical cobblestone-like morphology, and expressed endothelial markers (CD31, vWF, and VE-cadherin (CD144)) as characterized by immunohistochemistry (
Mesoderm precursor cells were also cultured under conditions suitable for maintaining MSCs in culture (standard culture conditions (37° C. incubator at 5% CO2) with MSC growth medium (15˜20% fetal-bovine serum and 1% penicillin—streptomycin in alpha minimal essential medium)), which revealed the mesoderm precursors can be induced to form MSC-like cells. The MSC phenotype of these cells was validated by observing the expression of CD90, CD73, and CD105, but not CD31 or CD45, as detected by FACS analysis (
The mesoderm precursors were cultured under conditions promoting SMC propagation and maturation (standard culture conditions (37° C. incubator at 5% CO2) with SMC growth medium (SmGM-2™, Lonza)). This caused the mesodermal precursor cells to display SMC-like properties, such as a spindle-like morphology and the strong expression of smooth muscle-specific markers, including α-SMA, calponin, and SM22, as confirmed by FACS analysis and immunohistochemistry (
To test the hematopoietic lineage differentiation potential, the hiPSCs were cultured in Matrigel™ coated plates in MDM for up to three weeks. Some of the attached mesoderm precursor cells began to float starting on day 3 in the culture, and the numbers gradually increased with time. The suspension cells exhibited morphology reminiscent of primitive human hematopoietic stem/progenitors (
Table 5 shows a particular embodiment of MDM1.
MDM supplemented with hematopoietic cytokines (SCF, Flt-3 ligand and TPO) is named MDM+. MDM1 supplemented with hematopoietic cytokines (SCF, Flt-3 ligand and TPO) is referred to as MDM1+. Table 6 shows the composition of MDM1+.
Compared to MDM or MDM+, iPSC differentiation with MDM1 or MDM1+ increases significantly the total number of supernatant cells (
Human iPSC-derived supernatant cells were differentiated with MDM1 and MDM1+ using the otherwise unmodified protocol described in Examples 1 to 3. At day 10 of differentiation, the differentiation protocol was modified to further support hematopoietic differentiation. The protocol is unchanged for differentiation of the other 3 cell types described in Examples 1 to 3, namely, mesenchymal stem cells (MSC), smooth muscle cells (SMC), and unlimited functional endothelial cells (UFEC).
For hematopoietic differentiation, supernatant cells obtained from day 10 of differentiation were cultured in the upper chamber of a Transwell™ insert (Corning Inc.) in commercially available hematopoietic culture medium containing: 90% RPMI 1640 Medium (Gibco, Cat#11875-119), 10% Fetal Bovine Serum (Atlanta Biologicals, Cat# S10250), recombinant human SCF (Stemcell Technologies Inc.) at 100 ng/ml, recombinant human Flt-3 ligand (Stemcell Technologies Inc.) at 100 ng/ml, and recombinant human thrombopoietin (Stemcell Technologies Inc.) at 100 ng/ml, and recombinant human granulocyte/macrophage colony-stimulating factorat at 100 ng/ml (PeproTech, Cat# AF-300-03). The lower chamber of the Transwell insert was occupied by human umbilical vein endothelial cells (HUVEC) cultured in commercially available endothelial cell culture medium EGM™ BulletKit™ (Lonza, Cat# cc-3162). (
Under these co-culture conditions (in an incubator at 37° C. under 5% CO2), the majority of the cells within the Transwell (85.47%±9.5) gradually matured into hematopoietic stem/progenitor cells (HSPC), displaying the hematopoietic lineage markers CD34 and CD45, as confirmed by flow cytometry. After 7 days of co-culture in a Transwell insert, these cells are further differentiated to the monocytic lineage using a medium containing: 90% RPMI 1640 Medium (Gibco, Cat#11875-119), 10% Fetal Bovine Serum (FBS, Atlanta Biologicals, Cat# S10250), recombinant human SCF (Stemcell Technologies Inc.) at 100 ng/ml, recombinant human Flt-3 ligand (Stemcell Technologies Inc.) at 100 ng/ml, and recombinant human thrombopoietin (Stemcell Technologies Inc.) at 100 ng/ml, recombinant human granulocyte/macrophage colony-stimulating factorat at 100 ng/ml (PeproTech, Cat# AF-300-03), and recombinant human macrophage colony-stimulating factor at 100 ng/ml (PeproTech, Cat# AF-300-25). Phenotypic expression of monocytic markers (CD14, CD11b, and CD115) is confirmed by flow cytometry. These monocytes can subsequently be directed to differentiate into functional macrophages by using attachment cell culture conditions followed by RPMI 1640 (Gibco) supplemented with 10% FBS, 2 mmol/L L-glutamine, penicillin/streptomycin, and recombinant human granulocyte/macrophage colony-stimulating factor at 20 ng/ml (PeproTech), as confirmed by the in vitro phagocytosis assay.
