Cells within a tissue of a subject have differences in cell morphology and/or function due to varied analyte levels (e.g., gene and/or protein expression) within the different cells. The specific position of a cell within a tissue (e.g., the cell's position relative to neighboring cells or the cell's position relative to the tissue microenvironment) can affect, e.g., the cell's morphology, differentiation, fate, viability, proliferation, behavior, and signaling and cross-talk with other cells in the tissue.
Spatial heterogeneity has been previously studied using techniques that only provide data for a small handful of analytes in the context of an intact tissue or a portion of a tissue, or provide a lot of analyte data for single cells, but fail to provide information regarding the position of the single cell in a parent biological sample (e.g., tissue sample).
Tumors can be heterogeneous, with different regions within a tumor sample demonstrating different gene expression. A particular cancer, triple negative breast cancer (TNBC), accounts for 10-20% of all diagnosed breast cancer cases in the United States. TNBC is aggressive and exhibits poor prognosis due to resistance to traditional therapies and lack of identification of therapeutic targets. The lack of therapeutic targets, as well as the complexity of the disease, make it critical to further investigate the underlying biology in order to improve diagnosis and therapeutic outcome. TNBC is extremely complex, making it critical to understand the underlying biology to improve outcomes.

Spatial analysis methodologies can provide a vast amount of analyte level and/or expression data for a variety of multiple analytes within a sample at high spatial resolution, e.g., while retaining the native spatial context. Spatial analysis methods can include, e.g., the use of a capture probe including a spatial barcode (e.g., a nucleic acid sequence that provides information as to the position of the capture probe within a cell or a tissue sample (e.g., mammalian cell or a mammalian tissue sample) and a capture domain that is capable of binding to an analyte (e.g., a protein and/or nucleic acid) produced by and/or present in a cell.
Tissues and cells can be obtained from any source. For example, tissues and cells can be obtained from single-cell or multicellular organisms (e.g., a mammal). Tissues and cells obtained from a mammal, e.g., a human, often have varied analyte levels (e.g., gene and/or protein expression) which can result in differences in cell morphology and/or function. The position of a cell or a subset of cells (e.g., neighboring cells and/or non-neighboring cells) within a tissue can affect, e.g., the cell's fate, behavior, morphology, and signaling and cross-talk with other cells in the tissue. Information regarding the differences in analyte levels (gene and/or protein expression) within different cells in a tissue of a mammal can also help physicians select or administer a treatment that will be effective and can allow researchers to identify and elucidate differences in cell morphology and/or cell function in the single-cell or multicellular organisms (e.g., a mammal) based on the detected differences in analyte levels within different cells in the tissue. Differences in analyte levels within different cells in a tissue of a mammal can also provide information on how tissues (e.g., healthy and diseased tissues) function and/or develop.

Some general terminology that may be used in this disclosure can be found in Section (I)(b) of WO 2020/176788 and/or U.S. Patent Application Publication No. 2020/0277663, each of which is incorporated by reference in its entirety. Typically, a “barcode” is a label, or identifier, that conveys or is capable of conveying information (e.g., information about an analyte in a sample, a bead, and/or a capture probe). A barcode can be part of an analyte, or independent of an analyte. A barcode can be attached to an analyte. A particular barcode can be unique relative to other barcodes. For the purpose of this disclosure, an “analyte” can include any biological substance, structure, moiety, or component to be analyzed. The term “target” can similarly refer to an analyte of interest. Analytes can be broadly classified into one of two groups: nucleic acid analytes, and non-nucleic acid analytes. Examples of non-nucleic acid analytes include, but are not limited to, lipids, carbohydrates, peptides, proteins, glycoproteins (N-linked or O-linked), lipoproteins, phosphoproteins, specific phosphorylated or acetylated variants of proteins, amidation variants of proteins, hydroxylation variants of proteins, methylation variants of proteins, ubiquitylation variants of proteins, sulfation variants of proteins, viral coat proteins, extracellular and intracellular proteins, antibodies, and antigen binding fragments. In some embodiments, the analyte(s) can be localized to subcellular location(s), including, for example, organelles, e.g., mitochondria, Golgi apparatus, endoplasmic reticulum, chloroplasts, endocytic vesicles, exocytic vesicles, vacuoles, lysosomes, etc. In some embodiments, analyte(s) can be peptides or proteins, including without limitation antibodies and enzymes. Additional examples of analytes can be found in Section (I)(c) of WO 2020/176788 and/or U.S. Patent Application Publication No. 2020/0277663, each of which is incorporated by reference in its entirety. In some embodiments, an analyte is a biomarker disclosed herein.

A “biological sample” is typically obtained from the subject for analysis using any of a variety of techniques including, but not limited to, biopsy, surgery, and laser capture microscopy (LCM), and generally includes cells and/or other biological material from the subject. In some embodiments, a biological sample can be a tissue section. In some embodiments, a biological sample can be a fixed and/or stained biological sample (e.g., a fixed and/or stained tissue section). In some embodiments biological sample can be a cell culture sample. In some embodiments, a biological sample can be nervous tissue, blood, serum, plasma, cerebrospinal fluid, or bone marrow aspirate. Biological samples are also described in Section (I)(d) of WO 2020/176788 and/or U.S. Patent Application Publication No. 2020/0277663, each of which is incorporated by reference in its entirety.
In addition, spatial analysis methods can be performed on various types of samples, including tissues (e.g., tissue slices) or single cells (e.g., cultured cells). Exemplary methods and compositions relating to tissue or single-cell spatial analysis is found at least in WO 2020/176788 and/or U.S. Patent Application Publication No. 2020/0277663, each of which is incorporated by reference in its entirety. In some instances, one biological sample can be used for tissue and single cell analysis. For example, multiple serial slices (e.g., 10 μm in thickness) of a tissue can be cut. A first slice can be placed on an array and analyte capture as described herein can be performed. In some instances, a second slice of tissue can further undergo cellular dissociation, creating a sample with isolated cells that can be analyzed using spatial analysis methods. Briefly, in some instances, a tissue is minced into small pieces and treated with lysis buffer to homogenize the sample. The homogenous resultant can be filtered and centrifuged to collect a pellet of nuclei. The nuclei can be resuspended and used for single cell analysis methods described herein. Data captured from the second slice (i.e., the single nuclei data) could then be combined with the data from the first slice (i.e., the whole tissue data) to gain a higher cell type understanding and potentially deconvolve the cell type identity within each spot on the array. Additional methods of single cell isolation is found in Hu et al., Mol Cell. 2017 Dec. 7; 68(5):1006-1015.e7; Habib et al., Science, 2016 Aug. 26; 353(6302):925-8; Habib et al., Nat Methods, 2017 October; 14(10):955-958; Lake et al., Science, 2016 Jun. 24; 352(6293):1586-90; and Lacar et al., Nat Commun, 2016 Apr. 19; 7:11022; each of which is incorporated by reference in its entirety.
In another embodiment, two different samples are collected, whereby one sample is analyzed with intact tissue and a second tissue undergoes cell dissociation. Results from each biological sample can be compared to gain a higher cell type understanding and potentially deconvolve the cell type identity within each spot on the array. Array-based spatial analysis methods involve the transfer of one or more analytes from a biological sample to an array of features on a substrate, where each feature is associated with a unique spatial location on the array. Subsequent analysis of the transferred analytes includes determining the identity of the analytes and the spatial location of each analyte within the biological sample. The spatial location of each analyte within the biological sample is determined based on the feature to which each analyte is bound on the array, and the feature's relative spatial location within the array.
A “capture probe” refers to any molecule capable of capturing (directly or indirectly) and/or labelling an analyte (e.g., an analyte of interest) in a biological sample. In some embodiments, the capture probe is a nucleic acid or a polypeptide. In some embodiments, the capture probe includes a barcode (e.g., a spatial barcode and/or a unique molecular identifier (UMI)) and a capture domain. In some instances, the capture probe can include functional sequences that are useful for subsequent processing, such as functional sequence 604, which can include a sequencer specific flow cell attachment sequence, e.g., a P5 or P7 sequence, as well as functional sequence 606, which can include sequencing primer sequences, e.g., a R1 primer binding site, a R2 primer binding site. In some embodiments, sequence 604 is a P7 sequence and sequence 606 is a R2 primer binding site. Additional features of capture probes are described in Section (II)(b) of WO 2020/176788 and/or U.S. Patent Application Publication No. 2020/0277663, each of which is incorporated by reference in its entirety. Generation of capture probes can be achieved by any appropriate method, including those described in Section (II)(d)(ii) of WO 2020/176788 and/or U.S. Patent Application Publication No. 2020/0277663, each of which is incorporated by reference in its entirety.
In some embodiments, more than one analyte type from a biological sample can be detected (e.g., simultaneously or sequentially) using any appropriate multiplexing technique, such as those described in Section (IV) of WO 2020/176788 and/or U.S. Patent Application Publication No. 2020/0277663, each of which is incorporated by reference in its entirety.
In some embodiments, detection of one or more analytes (e.g., protein analytes) can be performed using one or more analyte capture agents. As used herein, an “analyte capture agent” refers to an agent that interacts with an analyte (e.g., an analyte in a sample) and with a capture probe (e.g., a capture probe attached to a substrate) to identify the analyte. In some embodiments, the analyte capture agent includes an analyte binding moiety and a capture agent barcode domain. Additional description of analyte capture agents can be found in Section (II)(b)(viii) of WO 2020/176788 and/or U.S. Patent Application Publication No. 2020/0277663, each of which is incorporated by reference in its entirety.
There are at least two general methods to associate a spatial barcode with one or more neighboring cells, such that the spatial barcode identifies the one or more cells, and/or contents of the one or more cells, as associated with a particular spatial location. One general method is to promote analytes out of a cell and towards a spatially-barcoded array (e.g., including spatially-barcoded capture probes). Another general method is to cleave spatially-barcoded capture probes from an array and promote the spatially-barcoded capture probes towards and/or into or onto the biological sample.
In some cases, capture probes may be configured to prime, replicate, and consequently yield optionally barcoded extension products from a template (e.g., a DNA or RNA template), or derivatives thereof (see, e.g., Section (II)(b)(ii) of WO 2020/176788 and/or U.S. Patent Application Publication No. 2020/0277663 regarding extended capture probes, the references of which are incorporated by reference in their entireties.). For example, in some cases, the capture probes may include mRNA specific priming sequences, e.g., poly-T primer segments that allow priming and replication of mRNA in a reverse transcription reaction or other targeted priming sequences. Alternatively or additionally, random RNA priming may be carried out using random N-mer primer segments of the barcoded oligonucleotides. Reverse transcriptases (RTs) can use an RNA template and a primer complementary to the 3′ end of the RNA template to direct the synthesis of the first strand complementary DNA (cDNA). Additional variants of spatial analysis methods, including in some embodiment's, an imaging step, are described in Section (II)(a) of WO 2020/176788 and/or U.S. Patent Application Publication No. 2020/0277663, each of which is incorporated by reference in its entirety. Analysis of captured analytes, for example, including sample removal, extension of capture probes, sequencing (e.g., of a cleaved extended capture probe and/or a cDNA molecule complementary to an extended capture probe), sequencing on the array (e.g., using in situ hybridization approaches), temporal analysis, and/or proximity capture, is described in Section (II)(g) of WO 2020/176788 and/or U.S. Patent Application Publication No. 2020/0277663. Some quality control measures are described in Section (II)(h) of WO 2020/176788 and/or U.S. Patent Application Publication No. 2020/0277663, each of which is incorporated by reference in its entirety.
Typically, for spatial array-based analytical methods, a substrate functions as a support for direct or indirect attachment of capture probes to features of the array. A “feature” is an entity that acts as a support or repository for various molecular entities used in sample analysis. In some embodiments, some or all of the features in an array are functionalized for analyte capture. Exemplary substrates are described in Section (II)(c) of WO 2020/176788 and/or U.S. Patent Application Publication No. 2020/0277663, each of which is incorporated by reference in its entirety. Exemplary features and geometric attributes of an array can be found in Sections (II)(d)(i), (II)(d)(iii), and (II)(d)(iv) of WO 2020/176788 and/or U.S. Patent Application Publication No. 2020/0277663, each of which is incorporated by reference in its entirety.
Generally, analytes can be captured when contacting a biological sample with a substrate including capture probes (e.g., substrate with capture probes embedded, spotted, printed on the substrate or a substrate with features (e.g., beads, wells) comprising capture probes). As used herein, “contact,” “contacted,” and/or “contacting,” a biological sample with a substrate refers to any contact (e.g., direct or indirect) such that capture probes can interact (e.g., bind covalently or non-covalently (e.g., hybridize)) with analytes from the biological sample. Capture can be achieved actively (e.g., using electrophoresis) or passively (e.g., using diffusion). Analyte capture is further described in Section (II)(e) of WO 2020/176788 and/or U.S. Patent Application Publication No. 2020/0277663, each of which is incorporated by reference in its entirety.
In some cases, a spatial analysis can be performed by attaching and/or introducing a molecule (e.g., a peptide, a lipid, or a nucleic acid molecule) having a barcode (e.g., a spatial barcode) to a biological sample (e.g., to a cell in a biological sample). In some embodiments, a plurality of molecules (e.g., a plurality of nucleic acid molecules) having a plurality of barcodes (e.g., a plurality of spatial barcodes) are introduced to a biological sample (e.g., to a plurality of cells in a biological sample) for use in spatial analysis. In some embodiments, after attaching and/or introducing a molecule having a barcode to a biological sample, the biological sample can be separated into single cells or cell groups for analysis. Some such methods of spatial analysis are described in Section (III) of WO 2020/176788 and/or U.S. Patent Application Publication No. 2020/0277663, each of which is incorporated by reference in its entirety.
Some exemplary particular spatial analysis workflows are described in the Exemplary Embodiments section of WO 2020/176788 and/or U.S. Patent Application Publication No. 2020/0277663, each of which is incorporated by reference in its entirety.
In some embodiments, a spatial analysis can be performed using dedicated hardware and/or software, such as any of the systems described in Sections (II)(e)(ii) and/or (V) of WO 2020/176788 and/or U.S. Patent Application Publication No. 2020/0277663, each of which is incorporated by reference in its entirety.
Disclosed herein are methods to enhance detection of one or more target analytes. The methods disclosed herein may combine methods of spatial detection while enhancing detection of particular analytes of interest. In some embodiments, the methods of spatial detection include contacting a capture probe comprising a spatial barcode and a capture domain (e.g., an analyte-binding sequence) to an analyte. In some embodiments, the capture probe hybridized to the analyte can be extended using a polymerase (e.g., a reverse transcriptase) using the hybridized analyte as a template, to generate an extended capture probe. In some embodiments, a 3′ end of the capture probe hybridized to the analyte can be extended using a polymerase (e.g., a reverse transcriptase) using the hybridized analyte as a template, to generate an extended capture probe. In some embodiments, a 5′ end of the capture probe hybridized to the analyte can be extended using a polymerase (e.g., a reverse transcriptase) using the hybridized analyte as a template, to generate an extended capture probe. The extended capture probe can be amplified (e.g., via second strand synthesis) to generate a single-stranded nucleic acid comprising a sequence that is complementary to the extended capture probe. The single-stranded nucleic acid comprising a sequence that is complementary to the extended capture probe can be used to generate or can be a part of a nucleic acid library. A subset of nucleic acids in the nucleic acid library can be enriched using any of the exemplary enrichment methods described herein (e.g., hybridization using any of the oligonucleotides including a bait domain described herein). Compared to methods involving whole genome analysis (e.g., whole transcriptome sequencing), targeted spatial gene expression profiling as described herein can, in some cases, reduce sequencing costs by avoiding the sequencing and/or detection of analytes that are not of interest (e.g., ribosomal, mitochondrial, or house-keeping transcripts).
The methods disclosed herein include identifying a location of an analyte in a biological sample. In some embodiments, the methods include (a) contacting a plurality of nucleic acids with a plurality of bait oligonucleotides, where a nucleic acid of the plurality of nucleic acids comprises (i) a spatial barcode or a complement thereof, and (ii) a portion of a sequence of an analyte from a biological sample, or a complement thereof; and a bait oligonucleotide of the plurality of bait oligonucleotides comprises a domain that binds specifically to (i) all or a portion of the spatial barcode or a complement thereof, and/or (ii) all or a portion of the sequence of the analyte from the biological sample, or a complement thereof, and a molecular tag; (b) enriching a complex of the bait oligonucleotide specifically bound to the nucleic acid using a substrate comprising an agent that binds specifically to the molecular tag; and (c) determining (i) all or a portion of the sequence of the spatial barcode or the complement thereof, and (ii) all or a portion of the sequence of the analyte from the biological sample, and using the determined sequences of (i) and (ii) to identify the location of the analyte in the biological sample. In some embodiments, the methods further include generating the plurality of nucleic acids prior to the steps of (a)-(c) above. In some embodiments, for example, the methods further include generating the plurality of nucleic acids by contacting the biological sample with a substrate comprising a plurality of attached capture probes, wherein a capture probe of the plurality comprises (i) the spatial barcode and (ii) a capture domain that binds specifically to a sequence present in the analyte. Then, in some embodiments, the capture probe is extended using the analyte that is specifically bound to the capture domain as a template to generate an extended capture probe. In some embodiments, the 3′ end of the capture probe is extended using the analyte that is specifically bound to the capture domain as a template to generate an extended capture probe. In some embodiments, the 5′ end of the capture probe is extended using the analyte that is specifically bound to the capture domain as a template to generate an extended capture probe. In some embodiments, the extended capture probe is amplified to produce the nucleic acid.
(a) Nucleic Acid Detection and Library Preparation
Also disclosed herein are methods of preparing a library of nucleic acids (e.g., a plurality of nucleic acids). In some embodiments, the library of nucleic acids (e.g., a plurality of nucleic acids) include one or more nucleic acids of interest, whose detection can be enhanced using hybridization methods. Some embodiments of any of the methods described herein can include contacting a biological sample with a substrate comprising a plurality of attached capture probes, wherein a capture probe of the plurality comprises (i) a spatial barcode and (ii) a capture domain that binds specifically to a sequence present in a analyte; extending a 3′ end of the capture probe using the analyte that is specifically bound to the capture domain as a template to generate an extended capture probe; and amplifying the extended capture probe to produce a nucleic acid.
In some embodiments, the biological sample is a tissue sample. In some embodiments, the biological sample is a section of a tissue sample. In some embodiments, the biological sample is a fresh tissue sample. In some embodiments, the biological sample is a fresh-frozen tissue sample. In some embodiments, the biological sample is a tissue sample that has been formalin-fixed and paraffin-embedded (FFPE) (i.e., an FFPE sample). In some embodiments, the biological sample is a tissue sample embedded in optimal cutting temperature (OCT) compound. In some embodiments, the biological sample has been previously stained (e.g., immunohistochemistry (IHC) or histological staining) and imaged, and optionally, destained. In some embodiments, the analyte is a nucleic acid. In some embodiments, the nucleic acid is DNA (e.g., genomic DNA, mitochondrial DNA, or exosomal DNA). In some embodiments, the nucleic acid is RNA. In some embodiments, the RNA is mRNA. In some embodiments, the nucleic acid comprises DNA.
In some embodiments, the biological sample is permeabilized. In some examples, a biological sample is permeabilized to allow analytes to be released from one or more cells within the biological sample. In some embodiments, analytes released from the one or more cells can be amplified before they are contacted with a capture probe.
In some embodiments, the amplification of the extended capture probe results in the production of a single-stranded nucleic acid including a sequence that is complementary to all or a portion of the sequence of the extended capture probe. In some examples, the single-stranded nucleic acid can be denatured or dissociated from the extended capture probe.
In some embodiments, the biological sample is affixed to a slide. In some embodiments, the sample is stained prior to creation of the library of nucleic acids (e.g., plurality of nucleic acids). In some embodiments, the biological sample is stained while the biological sample is on the slide. In some embodiments, the stained biological sample is imaged prior to creation of the library of nucleic acids (e.g., plurality of nucleic acids).
In some embodiments, staining includes biological staining techniques such as H&E staining. In some embodiments, staining includes identifying analytes using fluorescently conjugated antibodies (e.g., immunofluorescence). In some embodiments, a biological sample is stained using two or more different types of stains, or two or more different staining techniques (e.g., IF, IHC, and/or H&E staining). For example, a biological sample can be prepared by staining and imaging using one technique (e.g., H&E staining and bright field imaging), destained (e.g., quenching or photobleaching), followed by staining and imaging using another technique (e.g., IHC/IF staining and fluorescence microscopy) for the same biological sample.
In some embodiments, biological samples can be destained prior to creation of the spatial library of nucleic acids. Methods of destaining or discoloring a biological sample are known in the art, and generally depend on the nature of the stain(s) applied to the biological sample.
In some embodiments, after creation of the library of nucleic acids (e.g., plurality of nucleic acids), one or more bait oligonucleotides (e.g., from one or more panels as described herein) are hybridized to a plurality of nucleic acids. In some embodiments, the nucleic acids include all or a portion of a sequence of an analyte of interest or a complement thereof and/or include all or a portion of a spatial barcode of interest or a complement thereof. In some embodiments, one or more bait oligonucleotides are hybridized to the nucleic acid including all or a portion of a sequence of analyte of interest or a complement thereof, and/or all or a portion of a spatial barcode of interest, or a complement thereof, before additional sequences, such as an adaptor (or a complement thereof), a primer binding site (or a complement thereof), and/or a poly(G/I) sequence are ligated or added to the nucleic acid (e.g., using a splint oligonucleotide).
In other embodiments, the library, the nucleic acid(s), or the enriched nucleic acid(s) can be quantified using quantitative PCT (qPCR). In some embodiments, the library, the nucleic acid(s), or the enriched nucleic acid(s) can be fragmented. In some embodiments, the library, the nucleic acid(s), or the enriched nucleic acid(s) can be fragmented by enzyme-based methods (e.g., by restriction enzymes, nicking enzymes and/or transposases). In some embodiments, the library, the nucleic acid(s), or the enriched nucleic acid(s) can be fragmented by endonucleases. In some embodiments, the library, the nucleic acid(s), or the enriched nucleic acid(s) can be fragmented by mechanical shearing (e.g., acoustic shearing, hydrodynamic shearing, and/or nebulization). In some embodiments, the library, the nucleic acid(s), or the enriched nucleic acid(s) can be fragmented by combined enzyme-based methods and mechanical shearing. In some embodiments, the library, the nucleic acid(s), or the enriched nucleic acid(s) can be further processed via end-repair, poly-A tailing, or a combination thereof. In some embodiments, adaptors are ligated to each nucleic acid or enriched nucleic acid sequence. In some embodiments, the adaptors can be ligated to the 3′ end of the nucleic acid or enriched nucleic acid sequence. In some embodiments, the adaptors can be ligated to the 5′ end of the nucleic acid sequence or enriched nucleic acid sequence. In some embodiments, the adaptors can be nucleic acid sequences that add a function, e.g., spacer sequences, primer sequences/sites, barcode sequences, unique molecular identifier (UMI) sequences, linkers, and/or sequencing adaptors.
In some embodiments, the methods disclosed herein include sample index (SI) PCR, which adds nucleic acid sequences (e.g., barcodes) to the 5′ and/or 3′ ends of a nucleic acid sequence or an enriched nucleic acid sequence. In some embodiments, SI-PCR is a PCR reaction that introduces sample index sequences (e.g., i5 and i7) to the 5′ and/or 3′ ends of a nucleic acid sequence or an enriched nucleic acid sequence. In some embodiments, methods for SI-PCR add the i5 sample index sequence. In some embodiments, methods for SI-PCR add the i7 sample index sequence. In some embodiments, a P5 adapter is added to a nucleic acid sequence or an enriched nucleic acid sequence. In some embodiments, a P7 adapter is added to a nucleic acid sequence or an enriched nucleic acid sequence. In some embodiments, SI-PCR is performed before bait oligonucleotide enrichment of a nucleic acid of interest. In some embodiments, SI-PCR is performed after bait oligonucleotide enrichment of a nucleic acid of interest.
In some embodiments, the nucleic acid of interest (before or after enrichment using a bait oligonucleotide) or a library generated from the same can be dried. In some embodiments, drying includes a dehydrating process such as heat, a vacuum, lyophilization, desiccation, filtration, and air-drying. In some embodiments, drying can be performed for at least 1 hour, at least 2 hours, at least 3 hours or at least 4 hours. In some embodiments, the nucleic acid of interest (before or after enrichment using a bait oligonucleotide) or a library generated from the same is not dried.
In alternative embodiments, combined with (1) capture of an analyte on an array and/or (2) target enrichment, or independent of (i.e., methods do not include) capture and target enrichment methods, additional methods are provided herein for analyzing an analyte using in situ methods. In some instances, the methods include amplifying an analyte using in situ methods. For instance, in some embodiments where an analyte is amplified, the amplification is performed by rolling circle amplification. In some embodiments, the capture probe to be amplified includes sequences (e.g., docking sequences, functional sequences, and/or primer sequences) that enable rolling circle amplification. In one example, the capture probe can include a functional sequence that is capable of binding to a primer used for amplification. In another example, the capture probe can include one or more docking sequences (e.g., a first docking sequence and a second docking sequence) that can hybridize to one or more oligonucleotides (e.g., a padlock probe(s)) used for rolling circle amplification. In some embodiments, additional probes are affixed to the substrate, where the additional probes include sequences (e.g., a docking sequence(s), a functional sequence(s), and/or a primer sequence(s)) that enable rolling circle amplification. In some embodiments, the spatial array is contacted with an oligonucleotide (e.g., a padlock probe). As used herein, a “padlock probe” refers to an oligonucleotide that has, at its 5′ and 3′ ends, sequences that are complementary to adjacent or nearby target sequences (e.g., docking sequences) on a capture probe. Upon hybridization to the target sequences (e.g., docking sequences), the two ends of the padlock probe are either brought into contact or an end is extended until the two ends are brought into contact, allowing circularization of the padlock probe by ligation (e.g., ligation using any of the methods described herein). In some embodiments, after circularization of the oligonucleotide, rolling circle amplification can be used to amplify the ligation product, which includes at least a capture domain and a spatial barcode from the capture probe. In some embodiments, amplification of the capture probe using a padlock oligonucleotide and rolling circle amplification increases the number of capture domains and the number of spatial barcodes on the spatial array. Padlock probes are disclosed in U.S. Pat. No. 8,551,710 and US-2020-0224244-A1, each of which is incorporated by reference in its entirety.
In some embodiments, the one or more additional biomarkers are detected using in situ sequencing. In situ sequencing typically involves incorporation of a labeled nucleotide (e.g., fluorescently labeled mononucleotides or dinucleotides) in a sequential, template-dependent manner or hybridization of a labeled primer (e.g., a labeled random hexamer) to a nucleic acid template such that the identities (i.e., nucleotide sequence) of the incorporated nucleotides or labeled primer extension products can be determined, and consequently, the nucleotide sequence of the corresponding template nucleic acid. Aspects of in situ sequencing are described, for example, in Mitra et al., (2003) Anal. Biochem. 320, 55-65, and Lee et al., (2014) Science, 343(6177), 1360-1363, the entire contents of each of which are incorporated herein by reference.
In addition, examples of methods and systems for performing in situ sequencing are described in PCT Patent Application Publication Nos. WO2014/163886, WO2018/045181, WO2018/045186, and in U.S. Pat. Nos. 10,138,509 and 10,179,932, the entire contents of each of which are incorporated herein by reference. Exemplary techniques for in situ sequencing include, but are not limited to, STARmap (described for example in Wang et al., (2018) Science, 361(6499) 5691), MERFISH (described for example in 2017/0220733 and in Moffitt, (2016) Methods in Enzymology, 572, 1-49), SeqFISH (described for example in U.S. Pat. No. 10,457,980), hybridization chain reaction amplification (described in U.S. Pat. No. 8,507,204) and FISSEQ (described for example in U.S. Patent Application Publication No. 2019/0032121). The entire contents of each of the foregoing references are incorporated herein by reference.
(b) Targeted Capture of Analytes Using Hybridization of Bait Oligonucleotides
(i) Design of Bait Oligonucleotides
In some embodiments, bait oligonucleotide sets are designed to target and hybridize to a plurality of nucleic acids (e.g., to prepared spatial libraries; e.g., to prepared cDNA libraries). In some embodiments, bait oligonucleotide sets hybridize to targeted nucleic acids (e.g., cDNA) in a library. In some embodiments, the hybridized product (e.g., the bait oligonucleotide and hybridized nucleic acid) are then captured by avidin beads. In some embodiments, the hybridized product (e.g., the bait oligonucleotide and hybridized nucleic acid) are then captured by streptavidin beads. Unhybridized nucleic acids are washed away. Then, the targeted product is reamplified and sequenced. In some embodiments, the reamplifed targeted product can be fragmented, ligated with adaptor sequences, and amplified by SI-PCR.
In some embodiments, disclosed herein are methods to design and test candidate bait oligonucleotide sequences. Candidate bait oligonucleotide sequences are designed so that each bait oligonucleotide sequence theoretically hybridizes to a unique target of interest. Accordingly, in some embodiment, the designed bait oligonucleotides are at least 40 nucleotides in length. To identify a bait oligonucleotide of interest, at unique 40 nucleotide sections of the human transcriptome are identified and aligned to the genome using an aligner designed for aligning RNA-seq data. In some embodiments, bait oligonucleotides are designed to hybridize to a particular exon. In some embodiments, bait oligonucleotides are designed to span an exon-exon junction. In some embodiments, bait oligonucleotides can hybridize to a target, allowing for identification of splicing and alternative splicing transcripts in the transcriptome. Using the alignments, sequences that align to the genome one or more times are identified and cataloged. Each bait designed can be tested against (i.e., compared to) a sequence identified in the genome. If the sequences in the bait oligonucleotide and in the genome do not match, then the bait can be tested and/or in one or more panels as disclosed herein.
However, if the sequences in the bait oligonucleotide and in the genome match, then in some embodiments, a modified bait is designed. To prepare a modified bait, one can slide the initial sequence+/−40 bp from the original position to identify a potentially new bait oligonucleotide. With each design, the new bait oligonucleotide is tested against the genome. After all such candidates are cataloged, the bait oligonucleotides that are ultimately included in one or more panels described herein are ordered (i.e., ranked) based on the bait oligonucleotide length (i.e. a longer bait is prioritized) and then by distance to the original intended position (with priority to sequences closer to the original intended position). However, if no bait meets the required criteria, that bait is dropped and no bait is designed at that position.
In some embodiments, the bait oligonucleotide sequence is 40 nucleotides long. In some embodiments, the bait oligonucleotide sequence is between 40 and 160 nucleotides long.

(2) Hybridization of Bait Oligonucleotides Directly to Analytes of Interest.
In some embodiments, a bait oligonucleotide (e.g., a set of bait oligonucleotides from one or more panels) can be added directly to an analyte. In some embodiment, the bait oligonucleotide is directly associated with (i.e., conjugated to) a detectable moiety at the 3′ end. In some embodiment, the bait oligonucleotide is directly associated with (i.e., conjugated to) a detectable moiety at the 5′ end. In some embodiments, the detectable moiety is a fluorescent marker as described herein.
In some embodiments, target-specific reactions are performed in the biological sample. In some embodiments, a nucleic acid analyte is denatured to create single-stranded analytes. In some embodiments, a bait oligonucleotide binds (e.g., hybridizes) directly to an analyte (e.g., a single-stranded analyte), and the detectable moiety (e.g., the fluorescent marker) can be identified using one or more imaging techniques disclosed herein. In some embodiments, target-specific reactions include in situ hybridization of the bait oligonucleotide to an analyte. In some embodiment, the in situ hybridization is fluorescence in situ hybridization (FISH). In some embodiments, the fluorescent marker can serve as a marker to purify an analyte of interest. In some embodiments, fluorescence microscopy can be used to locate the fluorescently-bound bait oligonucleotides. In some embodiments, analytes that are not hybridized to the bait oligonucleotide can be washed away. In some embodiments, the wash methods include isolating only those analytes that fluoresce.

In some embodiments, the hybridized analyte/bait oligonucleotide can be cleaved from the substrate. In some embodiments, the spatially-barcoded array populated with capture probes can be contacted with a sample. The spatially-barcoded capture probes are cleaved and then interact with cells within the provided biological sample. In some embodiments, each capture probe can optionally include at least one cleavage domain. The cleavage domain represents the portion of the probe that is used to reversibly attach the probe to an array feature. Further, one or more segments or regions of the capture probe can optionally be released from the array feature by cleavage of the cleavage domain.

In some embodiments, the capture probe can also include a cleavage site (e.g., a cleavage recognition site of a restriction endonuclease), a photolabile bond, a thermosensitive bond, or a chemical-sensitive bond. In some embodiments, once the spatially-barcoded capture probe is associated with a particular cell, the sample can be optionally removed for analysis.

(3) Downstream Application after Hybridization of Bait Oligonucleotides
In some embodiments of methods provided here, RNA-templated ligation is used to interrogate spatial gene expression in a biological sample (e.g., an FFPE tissue section). In some aspects, the steps of RNA-templated ligation include: (1) hybridization of pairs of bait oligonucleotides to a nucleic acid (e.g., a single-stranded cDNA or RNA molecule); (2) ligation of adjacently annealed probe pairs in situ; (3) RNase H treatment that (i) releases RNA-templated ligation products from the tissue (e.g., into solution) for downstream analysis and (ii) destroys unwanted DNA-templated ligation products; and optionally, (4) amplification of RNA—templated ligation products (e.g., by multiplex PCR).
In some aspects, RNA-templated ligation is used for detection of a target analyte, determination of sequence identity, and/or expression monitoring and transcript analysis. In some aspects, RNA-templated ligation allows for detection of a particular change in a nucleic acid (e.g., a mutation or single nucleotide polymorphism (SNP)), detection or expression of a particular nucleic acid, or detection or expression of a particular set of nucleic acids (e.g., in a similar cellular pathway or expressed in a particular pathology). In some embodiments, the methods that include RNA-templated ligation are used to analyze nucleic acids, e.g., by genotyping, quantitation of DNA copy number or RNA transcripts, localization of particular transcripts within samples, and the like. In some aspects, systems and methods provided herein that include RNA-templated ligation identify single nucleotide polymorphisms (SNPs). In some aspects, such systems and methods identify mutations.
In some aspects, disclosed herein are methods of detecting RNA expression that include bringing into contact a first bait oligonucleotide, a second bait oligonucleotide, and ligase (e.g., T4 RNA ligase). In some embodiments, the first bait oligonucleotide and the second bait oligonucleotide are designed to hybridize to a target sequence such that the 5′ end of the first bait oligonucleotide and the 3′ end of the second bait oligonucleotide are adjacent and can be ligated. After hybridization, a ligase (e.g., T4 RNA ligase) ligates the first bait oligonucleotide and the second bait oligonucleotide if the target sequence is present in the target sample, but does not ligate the first bait oligonucleotide and the second bait oligonucleotide if the target sequence is not present in the target sample. The presence or absence of the target sequence in the biological sample can be determined by determining whether or not the first and second bait oligonucleotides were ligated in the presence of ligase.
In some aspects, two or more RNA analytes are analyzed using methods that include RNA-templated ligation. In some aspects, when two or more analytes are analyzed, a first and second bait oligonucleotide that is specific for (e.g., specifically hybridizes to) each RNA analyte are used.
In some aspects, three or more bait oligonucleotides are used in RNA-templated ligation methods provided herein. In some embodiments, the three or more bait oligonucleotides are designed to hybridize to a target sequence such that the three or more probes hybridize adjacent to each other such that the 5′ and 3′ ends of adjacent probes can be ligated. In some embodiments, the presence or absence of the target sequence in the biological sample can be determined by determining whether or not the three or more bait oligonucleotide were ligated in the presence of ligase.
Spatial transcriptomics technology has helped address the limitations of traditional pathological examination, combining the benefits of histological techniques and massive throughput of RNA-seq. Disclosed herein are methods of combining spatial transcriptomics technology with histological techniques to resolve the expression profile of a tumor. In particular, as disclosed herein are methods to capture an analyte of interest in an unbiased fashion. Then, imaging and sequencing data are processed together resulting in gene expression mapped to image position.
As disclosed herein, spatial patterns of gene expression that agreed with annotations from pathological examination were combined with immunohistochemical staining for tumor infiltrating lymphocytes, a hallmark of Triple Negative Breast Cancer (TNBC). By aggregating data from serial tissue sections, the delineation of gene expression patterns and cell-type identification were improved. These data were combined with 3′ single-nucleus RNA-seq from the same sample, generating cell-type expression profiles that were used to estimate the proportion of cell-types observed at a given position in the tissue section. Importantly, as disclosed herein, an enrichment strategy to select for cancer-associated genes was used. The enrichment strategy as shown herein showed concordance with the full transcriptome assay, suggesting that a targeted sequencing approach can be used where a fixed gene panel is appropriate.

(b) Panel Capture Methods
In some embodiments, where the analyte is a nucleic acid analyte, one or more RNA analyte species of interest can be selectively enriched. For example, one or more species of RNA of interest can be selected by addition of one or more oligonucleotides to the sample. In some embodiments, the additional oligonucleotide is a sequence used for priming a reaction by a polymerase. For example, one or more primer sequences with sequence complementarity to one or more RNAs of interest can be used to amplify the one or more RNAs of interest, thereby selectively enriching these RNAs. In some embodiments, an oligonucleotide with sequence complementarity (e.g. a probe) to the complementary strand of captured RNA (e.g., cDNA) can bind to the cDNA. For example, biotinylated oligonucleotides with sequence complementary to one or more cDNA of interest binds to the cDNA and can be selected using biotinylation-strepavidin affinity using any of a variety of methods known to the field (e.g., streptavidin or avidin beads). Other non-nucleic acid affinity moieties are known in the art, for example, 2-(4-Hydroxyphenylazo)benzoic acid (HABA).
Alternatively, one or more species of RNA can be down-selected (e.g., removed) using any of a variety of methods. For example, probes can be administered to a sample that selectively hybridize to ribosomal RNA (rRNA), thereby reducing the pool and concentration of rRNA in the sample. Subsequent application of the capture probes to the sample can result in improved capture of other types of RNA due to the reduction in non-specific RNA present in the sample.
In some embodiments, an analyte of interest includes one or more isoforms (e.g., a plurality of isoforms). In some embodiments, the plurality of isoforms includes three or more isoforms for the first genetic target. Isoforms of a genetic target refer to mRNA sequences that originate from the same genomic locus but comprise different mRNA sequences, including but not limited to transcription start sites (TSSs), protein coding DNA sequences (CDSs), and/or untranslated regions (UTRs). These differences are caused by alternative splicing, variable promoter usage, gene fusions or deletions, single nucleotide polymorphisms (SNPs), and/or other mutations or post-transcriptional modifications of specific genes. Isoforms of a genetic target may have different functional capacities due to the differences in mRNA sequence of the coding sequences and/or the cis-regulatory elements in the promoter sequences. Such alternative sequences may be recognized by alternative transcription factors and produce differential gene expression or behavior.
In some embodiments, the plurality of isoforms comprises five or more isoforms for the first genetic target. In some embodiments, the plurality of isoforms comprises 2, 3, 4, 5, 6, 7, 8, 9, 10 or more isoforms for the first genetic target. In some embodiments, the first genetic target is a gene and the plurality of isoforms are transcriptional isoforms of the first genetic target. In some embodiments, the first genetic target is a regulator element, such as a promotor, enhancer, or repressor sequence. In some embodiments, the exact genetic function of the genetic target is not known. In some embodiments, the first genetic target is an intro sequence or an exon sequence.
In some embodiments, the methods disclosed herein include obtaining the plurality of analytes, wherein the plurality of analytes comprises a first subset of analytes and second subset of analytes. Each respective sequence in the first subset of analytes maps to a first genetic target that is characterized by a plurality of isoforms. For instance, in some embodiments, the first genetic target includes a reference isoform and an alternative isoform and thus there are two isoforms. In some embodiments, there are more than two isoforms at any given genetic target. In some embodiments, there are two or more, three or more, four or more, or five or more isoforms at a genetic target. Each respective analyte in the second subset of analytes maps to an off-target portion of a reference genome. While the analytes of the second subset may also indeed map to regions of the genome that have multiple isoforms, what distinguishes the analytes of the second subset and makes them members of the second subset is that they do not map to the genetic target.
In some embodiments, the method further comprises exposing the plurality of analytes to a plurality of nucleic acid baits of length K residues, thereby forming a plurality of nucleic acid bait—analyte complexes. In some embodiments, K is between 25 and 1000. In some embodiments, K is between 50 and 500. In some embodiments, K is between 90 and 150. In some embodiments, K is between 95 and 130. In some embodiments, K is 100 or 120.
In some embodiments, each respective nucleic acid bait in the plurality of nucleic acid baits that hybridizes to an isoform in the plurality of isoforms of the genetic target (i) selectively hybridizes to a portion of a first isoform in the plurality of isoforms, or (ii) selectively hybridizes to a portion of an isoform in the plurality of isoforms, other than the first isoform, and is represented by a corresponding portion of a directed graph that is at least a threshold number of edges away (e.g., 1 edge, 2 edges, 3 edges, 4 edges) from any portion of the directed graph that represents a nucleic acid bait that selectively hybridizes to a portion of the first isoform of the genetic target as described in further detail below.
In some embodiments, the hybridization of each respective nucleic acid bait in the plurality of nucleic acid baits to an isoform in the plurality of isoforms is performed a priori. In some such embodiments, an index of candidate baits is generated by determining the length of the genetic target, the length of the respective baits K, and the desired coverage of the nucleic acid baits to the genetic target. In some such embodiments, the index of candidate baits is generated using input values provided by the user or customer. In some such embodiments, the index of candidate baits is modified by repositioning each respective nucleic acid bait by +/−10 base pairs along the genetic target. In some such embodiments, the respective attributes (e.g., melting temperature, Tm) of each respective nucleic acid bait is compared to established parameters. In some such embodiments, the established parameters for nucleic acid baits is obtained through inputs provided by the user or customer. In some embodiments, each respective nucleic acid bait in the plurality of nucleic acid baits that hybridizes to an isoform in the plurality of isoforms of the first genetic target has a Tm with respect to the isoform that is between a first threshold temperature and a second threshold temperature. In some such embodiments, the first threshold temperature is between 65° C. and 85° C. and the second threshold temperature is between 90° C. and 110° C. In some such embodiments, the first threshold temperature is 75° C. and the second threshold temperature is 100° C. In some embodiments, each respective nucleic acid bait in the plurality of nucleic acid baits that hybridizes to an isoform in the plurality of isoforms of the first genetic target that has a Tm below the first threshold temperature or above the second threshold temperature is filtered from the pool of candidate nucleic acid baits.
In some embodiments, the first isoform in the plurality of isoforms of the first genetic target is a principal isoform for the genetic target. For example, in some embodiments, the isoforms in the plurality of isoforms of the first genetic target are ranked prior to hybridization of the nucleic acid baits, where the highest ranked isoform is considered the principal isoform. In some such embodiments, isoform rank assignment is informed by annotations for known isoforms of the genetic target, where annotations are based on functional and/or evolutionary conservation of a respective isoform in the plurality of isoforms.
In some embodiments, a respective nucleic acid bait in a plurality of nucleic acid baits for a respective analyte in a plurality of analytes mapping to a first genetic target is located at a position that is at least a minimum threshold distance from the 3′ end of the respective analyte. In some such embodiments, off-target hybridization of a respective nucleic acid bait to a respective analyte can occur where there are unannotated poly-A sites or poly-A sequences present in the genomic exon and/or mRNA sequence that cause oligo-dT mispriming. As a result, in some such embodiments, the optimal position for nucleic acid bait hybridization to a corresponding analyte is located at a position that is at least a minimum threshold distance from the 3′ end. Non-limiting examples of a minimum threshold distance are from 100 to 200 base pairs (bp), from 200 to 300 bp, from 300 to 400 bp, from 400 to 500 bp, from 500 to 600 bp, from 600 to 700 bp, from 700 to 800 bp, from 800 to 900 bp, from 900 to 1000 bp, or more than 1000 bp. In some embodiments, the percentage of analytes that preferentially hybridize to nucleic acid baits at positions at least a minimum threshold distance away from the 3′ end is between 0% and 10%, between 10% and 20%, or between 20% and 30%. In addition, in some embodiments, nodes and/or edges corresponding to sequences (e.g., analytes or regions of an isoform of a first genetic target) comprising unannotated poly-A sites or poly-A sequences in the mRNA sequence are removed from the directed graph.
In some embodiments, each respective nucleic acid bait in the plurality of nucleic acid baits shares less than a threshold percentage of sequence identity to any other nucleic acid bait in the plurality of nucleic acid baits. For instance, in some embodiments, each respective nucleic acid bait in the plurality of nucleic acid baits shares less than 100 percent, less than 98 percent, less than 96 percent, less than 94 percent, less than 92 percent, less than 90 percent, less than 88 percent, less than 86 percent, less than 84 percent, less than 82 percent, less than 80, less than 70 percent, less than 60 percent, less than 50 percent, or less than 40 percent identity to any other nucleic acid bait in the plurality of nucleic acid baits. In some embodiments, the threshold percentage of sequence identity shared between each respective nucleic acid bait in the plurality of nucleic acid baits to any other nucleic acid bait in the plurality of nucleic acid baits is ten percent, twenty percent, thirty percent, or between five and fifty percent. In some embodiments, the threshold of shared sequence identity between a respective nucleic acid bait in the plurality of nucleic acid baits to any other nucleic acid bait in the plurality of nucleic acid baits determines the presence and abundance of cross-hybridization of each respective nucleic acid bait to off-target analytes.
In some embodiments, the method further comprises selectively capturing the plurality of nucleic acid bait—analyte complexes thereby filtering the plurality of analytes. In some such embodiments, the plurality of nucleic acid bait—analyte complexes are selectively captured to a solid support. In some such embodiments, the solid support comprises a bead. In some further such embodiments, each nucleic acid bait in the plurality of nucleic acid baits comprises a binding moiety. The solid support comprises a plurality of capture moieties. A respective nucleic acid bait—analyte complex is captured on the solid support through a reaction between a capture moiety in the plurality of capture moieties and the corresponding binding moiety of the respective nucleic acid bait—analyte complex. A capture moiety in the plurality of capture moieties comprises avidin and the corresponding binding moiety comprises biotin. A capture moiety in the plurality of capture moieties comprises streptavidin and the corresponding binding moiety comprises biotin. In some embodiments, the plurality of nucleic acid baits are directed to a member selected from the group consisting of: whole or partial exome capture whole or partial transcriptome capture, panel capture, targeted exon capture, anchored exome capture, anchored transcriptome capture, and tiled genomic region capture.
For example, in some such embodiments, a plurality of analytes comprised of nucleic acid analytes (e.g. RNA, mRNA, cDNA or genomic DNA) that are optionally amplified and/or library prepared with functional sequences (e.g. barcodes, spatial barcodes, UMIs, linkers, and/or sequencing adaptors) are hybridized to nucleic acid baits that have sequence complementarity to a plurality of analytes of interest. In some such embodiments, the nucleic acid baits are biotinylated. Due to the strong affinity of biotin to streptavidin or avidin, in some embodiments the nucleic acid bait—analyte complexes are captured by streptavidin-coated beads (e.g., pull-down). Due to the strong affinity of biotin to avidin, in some embodiments the nucleic acid bait

(c) Integration of Single Nucleus RNA-Seq with Spatial Gene Expression Capture
Spatial gene expression as described herein provides a wealth of information regarding the location and abundance of a sample. In some instances, these methods are augmented by single-cell cell methods to further determine the cell type at a particular location in a sample. In some instances, the methods disclosed herein examine single cells in a first section of a tissue to identify cell make-up in the sample. Then, a second serial section is imaged and subjected to the spatial analysis methods disclosed herein (e.g., spatial detection using an array having capture probes; selective enrichment using one or more bait oligonucleotides disclosed herein). Using biomarkers associated with cell types, one can combine the cell make-up data with the spatial information to determine cell type in the sample. Combining spatial analysis with single cell analysis provides the ability to understanding microenvironments and cellular structure, including allowing the ability to understand the spatial distribution of cellular components.
In some instances, the methods of analyzing individual cells (i.e., individual nuclei) include steps of separating cells from a biological sample, isolating RNA from each cell, barcoding RNA from each cell, cDNA amplification and cleanup, and sequencing.
The methods disclosed herein allow for profiling of 500-100,000 individual cells per sample. In some instances, a pool of ˜3,500,000 barcodes are sampled separately to index each cell's transcriptome by partitioning thousands of cells into nanoliter-scale beads-in-emulsion, where all generated cDNA share a common barcode sequence. Libraries are generated and sequenced from the cDNA and barcodes are used to associate individual reads back to the individual partitions (i.e., cell). See e.g., Chromium Next GEM Single Cell 3′ Reagent Kits v3.1 User Guide, Document CG000204, November 2019, which is incorporated by reference in its entirety.
In some instances, the biological sample is a tissue. In some instances, the biological sample is a section of a tissue. In instances where Single Nucleus RNA-sequencing is used with spatial methods, serial sections of a tissue are used, one for each method. In some instances, the section is about 10 μm. In some instances, the section is about 5 μm to about 20 μm; about 5 μm to about 15 μm; or about 5 μm to about 10 μm.
In a single nucleus RNA-sequencing sample, the number of isolated nuclei can vary. In some instances the number of isolated nuclei range from about 500 nuclei to about 100,000 nuclei (e.g., about 500, about 1,000, about 2,000, about 3,000, about 4,000, about 5,000, about 6,000, about 7,000, about 8,000, about 9,000, 10,000, about 20,000, about 30,000, about 40,000, about 50,000, about 60,000, about 70,000, about 80,000, about 90,000, or about 1,000,000, nuclei).
The methods disclosed herein allow for identification of cell types based on known biomarkers or biomarkers disclosed herein. In some instances, single cells can be identified include one or more of T cells, B cells, cancer or tumor cells, tumor stem cells, CD49fhi mammary stem cells, CD163+ macrophages, CD80+ macrophages, alveolar secretory cells, luminal progenitor cells, stromal cells, plasmacytoid dendritic cells, mast cells, myoepithelial cells, mature luminal cells, endothelial lymphatic cells, and ductal cells.
Because one spot on an array can have multiple cells, it is necessary to deconvolute the spot in order to determine which cell type(s) are in each spot. In some instances, each spot includes about 1 to 10 cells (e.g., 1 to 5, 2 to 5, 2 to 4). Further, because each spot contains more than one cell it can be useful to estimate the proportion of a given cell type at each spot. This gives insight into spatial organization of cells as well as how different cell types might interact in space. Multiple methods of deconvolution of spots are known in the art. See Elosua et al., SPOTlight: Seeded NMF regression to Deconvolute Spatial Transcriptomics Spots with Single-Cell Transcriptomes; Maaskola et al., Charting Tissue Expression Anatomy by Spatial Transcriptome Deconvolution; and MuSiC.
A slide is prepared and kept for storage at −80° C. for less than a week. After being thawed, the biological sample is fixed by methanol, stained by H&E (Haemotoxylin and Eosin), and then imaged in bright field. Next, the fixed sample is permeabilized. Next, the first strand cDNA is synthesized and then denatured, followed by the second cDNA synthesis and denaturation. Next, the cDNA is transferred off the slide and quantified by qPCR. Next, the cDNA is amplified followed by quality control (QC). Next, the cDNA is modified by fragmentation, end repair and A-tailing, followed by adapter ligation. Next, sample index PCR (SI-PCR) is performed and the quality of the resulting library is checked by QC. The library as peppered above is dried down and hybridized with biotinylated baits. After the hybridization, the biotinylated baits is captured with streptavidin or avidin beads. The beads is washed and the retaining library is re-amplified as a new library. The quality of the new library is checked and used for downstream steps.
In an alternative way, the steps including hybridization using biotinylated baits, capture with streptavidin or avidin beads and washing is performed prior to the adapter ligation and SI-PCR steps.

In addition to identifying analytes of interest using the enrichment methods described herein, additional methods were performed on the samples. For example, detection of CD3 was determined using immunofluorescence. As shown in
To further identify genes that are differentially expressed in a breast cancer sample, spatial gene expression was analyzed. A breast cancer tissue sample was serially sectioned and placed onto a gene expression slide. The sample was then fixed, stained, and permeabilized, releasing mRNA. The released mRNA hybridized to spatially barcoded capture probes on the slide, allowing for the capture of global gene expression information. cDNA was then synthesized from captured mRNA and sequencing libraries were prepared. The libraries were then sequenced and further analyzed.
A pathologist annotated areas of the breast cancer tissue sample as invasive carcinoma, fibrous tissue, or ductal cancer in situ (DCIS).
The sequencing data from cDNA libraries were further analyzed. Using Seurat, 14 clusters (number 0-13) were identified as containing differentially expressed genes compared to other areas of the breast cancer tissue shown in
Lists of the most differentiated genes in each cluster are provided in Tables 3-16 (Clusters 0-13) below. Upregulated genes are designated by an increase in the average log fold change (avg_logFC), whereas downregulated genes are designated by a decrease in the ave_logFC.
Further, using Seurat, the most differentially-expressed genes in the breast cancer sample from
As shown in
The above data provide both individual gene markers and clusters of gene markers that are differentially expressed in a breast cancer sample. The individual gene markers and clusters of gene markers can be utilized to identify particular types of breast cancer (e.g., invasive carcinoma; DCIS) in a tissue sample, aiding in both diagnostic and therapeutic methods.
The spatial gene expression of invasive ductal carcinoma tissue from a female patient (ER+, PR−, HER2+) was profiled (BioIVT: Asterand—Case ID 66320; Specimen ID 116899F). As a control, the healthy tissue sections adjacent to the tumor were obtained. 4 replicates were used for each tissue type.

The expression levels of genes corresponding to human epidermal growth factor receptor 2 (Her2 or ERBB2), estrogen receptor (ER or ESR1), and progesterone receptor (PGR) in the tissue section are shown in
During breast cancer progression, the myoepithelial cells, which continue to surround preinvasive in situ carcinoma, gradually disappear (see, e.g., Gudjonsson, T. et al. Myoepithelial Cells: Their Origin and Function in Breast Morphogenesis and Neoplasia. J. Mammary Gland Biol. Neoplasia. 2009, 10, 261, incorporated herein by reference in its entirety). This phenomenon is clearly visualized in
Extensive heterogeneity exists in the breast cancer tumor microenvironment. However, clinical characterization has been primarily limited to pathologist annotation and tissue staining for three key genes: estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2). Triple negative breast cancer (TNBC) expresses none of the usual breast cancer therapeutic targets, including ER, PR, and HER2, making it unresponsive to either hormone therapy or targeted anti-HER2 drugs like trastuzumab.
Here, heterogeneity was examined using spatial methods. Briefly, human tissue specimens from triple negative breast cancer biopsy were obtained. 10 μm fresh-frozen tissue was sectioned using a cryostat. The sectioned tissues for each sample were placed onto a gene expression slide having approximately 5,000 gene expression spots, each of which contains spatially barcoded probes that bind mRNA from the cells in the tissue section above it.
The samples were fixed with acetone, and were stained with hematoxylin and eosin (H&E) according established protocols. H&E-stained tissues were images at 20× magnification using brightfield settings (see
After imaging, the tissue was prepared for spatial detection of gene expression. First, the tissue was permeabilized, releasing mRNA that bound to spatially barcoded capture probes on the slide. Briefly, tissues were washed and permeabilized using Proteinase K, incubated at 37° C. for at least 5 minutes and then washed to remove the protease.
After permeabilization, the released mRNA are allowed to hybridize to the capture domain on the capture probe immobilized on the spatial array via the polyA tail on the mRNA. The captured mRNA molecules were copied, using the capture probe as a template and the extension product was released from the spatial array. Briefly, the tissues were incubated with a second strand extension mix comprising Kapa Hifi DNA polymerase (Roche) for 25 minutes at 53° C. Following incubation, the extension mix was removed from the tissues and the tissues were washed with SSC. A solution of KOH was added to each of the tissue wells, the tissues were incubated at room temperature for 10 minutes to release the extension product from the spatial array and the supernatant from each tissue well was transferred for quantitation, library preparation and sequencing on the Illumina NextSeq sequencing instrument.
Sequencing results were analyzed and groups (i.e., clusters) of co-segregated genes were identified. Clusters were visualized spatially, with reference to the tissue section (
In general, there was high correlation between pathologist annotations and graph-based clusters determined by gene expression, particularly at region boundaries. For instance, as shown in
In the same sample used herein, these methods were used to identify expression of individual genes. For example, immunoglobulin lambda constant 2 (IGLC2;
Next, using the cancer panel described herein, similar cluster patterns and transcriptional profiles were resolved on a second section of the same TNBC sample. See
Taken together, these data demonstrate that, while whole transcriptome analysis is ideal for discovery and full characterization of graph-based clusters, targeted transcriptome analysis can provide exceptional value in the disambiguation of spatial heterogeneity and validation of preliminary findings.
Spatial gene expression spots have a diameter of about 55 microns and typically capture 1-10 cells per spot, depending on tissue thickness and cell density. To increase resolution of spatially resolved gene expression to the single cell level, single nuclei RNA-sequencing (snRNA-seq) of two TNBC samples was used to identify cellular subtypes within the tissue.
The methods of sectioning a tissue, staining and imaging the section, and capturing and amplification of mRNA was performed as described in Example 5. In addition, two additional fresh-frozen serial TNBC samples were sectioned, and individual nuclei were isolated using methods described previously. See Chromium Next GEM Single Cell 3′ Reagent Kits v3.1 User Guide, Document Number CG000204, Revision Date: November 2019. The resulting data for 86,249 single nuclei were aggregated before clustering and annotated manually using a marker gene approach. See
The extent and composition of immune cell infiltration in a tumor informs prognosis. Thus, combining snRNA-seq with spatial gene expression provides a unique view into both the identity of infiltrating cells as well as the extent of penetration into the cancerous region. By leveraging paired snRNA-seq data, spots containing specific subtypes of T cells were identified. As shown in
In the absence of snRNA-seq data, the predominant cell type in graph-based clusters can also be inferred based on gene expression. For example, as shown in
To discriminate between tumor and normal cells, spots were individually genotyped. Serial sections of TNBC individually genotyped by souporcell variant identification pipeline. See Heaton et al., bioRxiv 2019. doi.org/10.1101/699637. Variants called in bulk and genotyped using VarTrix6. Clustering (k=2) for identification of major distinct spot clusters shows refinement of tumor/normal boundaries. As shown in
An invasive ductal carcinoma tissue sample from a female patient (ER+, PR−, HER2+) (BioIVT: Asterand—Case ID 66320; Specimen ID 1168993F) was processed as described according to the steps in Example 1. Identification of genes of interest were determined using a cancer-specific panel (
The invasive ductal carcinoma sample was examined by a pathologist, who identified areas of the sample as having areas that were cancerous or non-cancerous. See
In addition, based on immune clustering, immune cells were identified. See
The snRNA-seq sample of Example 6 is further analyzed to identify the cell types in each spot on an array. Here, a first section of a sample is placed on an array and analyte capture as described herein. A second section of tissue undergoes cellular dissociation, creating a sample with isolated cells that can be analyzed. Briefly, a tissue is minced into small pieces and treated with lysis buffer to homogenize the sample. The homogenous resultant is filtered and centrifuged to collect a pellet of nuclei. The nuclei is resuspended and used for single cell analysis. Multiple methods of deconvolution of spots are known in the art. See Elosua et al., SPOTlight: Seeded NMF regression to Deconvolute Spatial Transcriptomics Spots with Single-Cell Transcriptomes; Maaskola et al., Charting Tissue Expression Anatomy by Spatial Transcriptome Deconvolution; and MuSiC.
Data captured from the second section (i.e., the single nuclei data) is combined with the data from the first section (i.e., the whole tissue data) to gain a higher cell type understanding and potentially deconvolve the cell type identity within each spot on the array.
