Cytokine injection

An inventory of the cytokines studied and their different names are proven in Fig. 1d and Supplementary Desk 1. We chosen 86 cytokines representing most members of main cytokine households, together with the next households: IL-1 (IL-1α, IL-1β, IL-1Ra, IL-18, IL-33, IL-36α and IL-36Ra); frequent γ-chain/IL-13/TSLP (IL-2, IL-4, IL-13, IL-7, TSLP, IL-9, IL-15 and IL-21); frequent β-chain (GM-CSF, IL-3 and IL-5); IL-6/IL-12 (IL-6, IL-11, IL-27, IL-30, IL-31, LIF, OSM, CT-1, NP, IL-12, IL-23 and IL-Y); IL-10 (IL-10, IL-19, IL-20, IL-22 and IL-24); IL-17 (IL-17A, IL-17B, IL-17C, IL-17D, IL-17E, IL-17F); interferon (kind I: IFNα1, IFNβ, IFNε and IFNκ; kind II: IFNγ; and sort III: IFNλ2); TNF (LTα1/β2, LTα2/β1, TNF, OX40L, CD40L, FasL, CD27L, CD30L, 4-1BBL, TRAIL, RANKL, TWEAK, APRIL, BAFF, LIGHT, TL1A and GITRL); complement (C3a and C5a); development issue (FLT3L, IL-34, M-CSF, G-CSF, SCF, EGF, VEGF, FGFβ, HGF and IGF-1). Consultant cytokines (TGFβ1, GDNF, persephin (PSPN), prolactin (PRL), leptin, adiponectin (AdipoQ), resistin (ADSF), noggin, decorin and thrombopoietin (TPO)) from different protein households had been additionally included.

Each recombinant mouse cytokine was obtained from no less than two separate orders. The endotoxin stage was <0.1 ng µg^–1 of protein for each cytokine per the knowledge from the distributors (Peprotech and R&D). To protect cytokine actions, carrier-free cytokines had been freshly reconstituted in response to the producer’s directions, saved at 4 °C in sterile situations and used inside 28 h after reconstitution. For every cytokine, 5 μg in 100 μl sterile PBS was injected into every animal. Wild-type feminine C57BL/6 mice had been bought from the Jackson Laboratory and utilized in research as 11–15-week-old younger adults after resting for no less than 1 week within the facility. Mice had been maintained on a 12-h mild–darkish cycle at room temperature (21 ± 2 °C) and 40 ± 10% humidity. Cytokines had been injected below the pores and skin (50% subcutaneous, 50% intradermal) bilaterally within the belly flank of every mouse. Bilateral skin-draining inguinal lymph nodes had been collected 4 h after injection at 6:00–8:00 and pooled for downstream processing. For every of the 86 cytokines, replicate experiments had been carried out in three unbiased C57BL/6 mice to make sure reproducibility. As a management, PBS alone was injected into mice for every experimental batch, totalling 14 PBS-injected mice. All experiments had been reviewed and authorized by the Broad Institute’s Institutional Animal Care and Use Committee.

Information era high quality assurance

All samples had been processed utilizing an optimized experimental pipeline to make sure high quality. Specifically, batch results that come up from experiments carried out on totally different days are recognized to be a serious supply of artefact in transcriptomic research. Due to this fact, batch-to-batch consistency was strictly experimentally ensured after which computationally verified. Particularly, the mice had been ordered from the identical batch and housed in the identical atmosphere. Animals had been randomly allotted to the experimental teams. Lymph nodes had been collected at 6:00–8:00 in all experiments to exclude the influence of circadian clocks on transcriptomic profiles. Samples had been processed recent in each experiment and had been stored on ice throughout processing each time potential. The identical researchers carried out the identical steps of the pattern processing and sequencing pipeline following the identical, extremely optimized procedures. The investigators performing animal experiments and RNA sequencing had been blinded from one another throughout knowledge assortment. The variety of batches was minimized each time potential. The three replicated mice for every cytokine had been processed in numerous batches to make sure that batch results, if any, wouldn’t affect organic interpretations. All samples had been sequenced on two sequencing runs, with the primary sequencing run containing the primary set of replicates and the second containing the second and third set of replicates. PBS controls had been included in each batch to make sure comparability, and transcriptomic profiles of PBS samples from totally different batches had been computationally in comparison with confirm batch-to-batch consistency (Prolonged Information Fig. 2a). In short, Euclidean distances had been calculated for every pair of PBS-treated cells of the identical cell kind primarily based on the whole transcriptome to make sure that the within-batch distances and between-batch distances had been comparable.

Lymph node dissociation and cell sorting for scRNA-seq experiments

An optimized pipeline for viable cell restoration and extra balanced cell-type illustration was used to course of lymph nodes for scRNA-seq. Lymph nodes had been enzymatically digested utilizing a protocol that maximizes the restoration of myeloid and stromal cells whereas sustaining excessive viability⁴⁰. In short, lymph nodes had been positioned in RPMI with collagenase IV, dispase and Dnase I at 37 °C, and cells had been collected as soon as they had been indifferent. The cells had been then instantly positioned on ice and washed with PBS supplemented with 2 mM EDTA and 0.5% biotin-free BSA, then filtered by a 70 µm cell strainer. Cells had been incubated with Fc blocking antibodies 4 °C, then with a biotinylated anti-CD3 and anti-CD19 antibody cocktail. Antibodies had been used at a dilution of 1:100. Streptavidin microbeads had been then added and the cells had been magnetically sorted utilizing MACS MS columns in response to the producer’s protocol (Miltenyi Biotec). After cell sorting, a small fraction of the CD3⁺ or CD19⁺ cells was pooled with CD3^–CD19^– cells for extra balanced illustration of all cell sorts and proceeded instantly to scRNA-seq.

scRNA-seq

Cell hashing was used to mix a number of samples into the identical single-cell emulsion channel⁴¹. The mouse cells obtained from totally different stimulation situations had been stained with TotalSeq antibodies (BioLegend anti-mouse hashtags 1–8; used at 1:100 dilution), washed 5 instances at 4 °C and pooled in PBS with 0.04% BSA in response to the producer’s protocol. Subsequent, 55,000 cells had been loaded onto a 10x Genomics Chromium instrument (10x Genomics) in response to the producer’s directions. The scRNA-seq libraries had been processed utilizing a Chromium Single Cell 3′ Library & Gel Bead v3 package (10x Genomics) with modifications for producing hashtag libraries⁴¹. High quality management for amplified cDNA libraries and closing sequencing libraries was carried out utilizing a Bioanalyzer Excessive Sensitivity DNA package (Agilent). scRNA-seq and hashing libraries had been normalized to 4 nM focus and pooled. The pooled libraries had been paired-end sequenced on a NovaSeq S4 platform concentrating on a median sequencing depth of 20,000 reads per cell for gene expression libraries, and on a NovaSeq S4 or SP platform concentrating on 5,000 reads per cell for hashtag libraries.

scRNA-seq knowledge pre-processing

The uncooked bcl sequencing knowledge had been processed utilizing the CellRanger (v.3.0) Gene Expression pipeline (10x Genomics), together with demultiplexing and alignment. Sequencing reads had been aligned to the mm10 mouse reference genome, and transcriptomic rely matrices had been assembled. Hashtag library FASTQ information had been processed utilizing the CITE-seq-Rely software (v.1.4.3; github.com/Hoohm/CITE-seq-Rely). Gene expression and hashtag had been matched utilizing the MULTIseqDemux operate of the Seurat R bundle (v.4.1)⁴². Cells with a number of hashtags had been thought of multiplets (for instance, doublets or triplets) and had been excluded from additional evaluation. The Seurat R pipeline was used to carry out high quality management to incorporate solely cells with >500 genes, >1,000 distinctive molecular identifiers and <10% mitochondrial gene content material. The expression matrix was globally scaled by normalizing the gene expression measurements by the full expression per cell. The ensuing values had been multiplied by a scale issue of 10,000 and pure log-transformed.

For the preliminary international evaluation of all cells, the highest 3,000 variable genes had been chosen for dimensionality discount evaluation. Principal element evaluation (PCA) was then used to denoise and to discover a lower-dimensional illustration of the information. The highest 75 principal parts (PCs) had been used for international clustering and for visualization utilizing a t-SNE map⁴³. Clusters had been recognized utilizing the Louvain clustering algorithm. This step resulted in a complete of 61 non-singleton international (stage 1) clusters (Prolonged Information Fig. 1d). We eliminated potential multiplets by eradicating the cells with the highest 2% gene counts in every cluster. As totally different cell sorts have variations within the numbers of genes detected on common, this step was completed on the cluster stage fairly than for all knowledge. For every stage 1 cluster of cells, we then carried out one other spherical of clustering (stage 2) to additional confirm the identification of every cluster and to take away potential doublets. This step resulted in a complete of 183 international stage 2 clusters. The cell-type identification of every stage 2 cluster was assigned on the premise of the expression of 115 recognized marker genes (Supplementary Desk 2). Clusters enriched for marker genes of a number of cell sorts had been thought of multiplets and eliminated. The highest DEGs between every cell kind and others are listed in Supplementary Desk 2.

Quantitative measures of reproducibility throughout animal replicates

A gene expression vector for every organic replicate was created for every cytokine stimulation situation in a given cell kind by taking the distinction between the typical expression vector of cytokine-treated cells and the typical expression vector of PBS-treated cells. Genes had been included in the event that they had been considerably differentially expressed (FDR < 0.05 and absolute log₂(FC) > 0.25) in contrast with PBS controls and had been expressed in >10% of cytokine-treated cells for upregulated genes or >10% of PBS-treated cells for downregulated genes. Rps, Rpl, mitochondrial genes and unlabelled genes had been excluded. Pairwise Pearson correlation coefficients had been then calculated for these vectors (Prolonged Information Fig. 2b).

Evaluation of entry to injected cytokines by every lymph node cell kind

To find out whether or not the injected cytokines will be accessed by every cell kind within the draining lymph nodes, we examined ISG expression ranges in cells handled with IFNα1 or IFNβ (IFNα1/IFNβ) or PBS for every cell kind. Sort I interferon was chosen for this evaluation given its robust induction of antiviral programmes in a variety of cell sorts. A most of 100 cells had been sampled from every situation. ISG scores had been obtained by summing the normalized expressions of ISGs in every cell. These scores had been then used to foretell whether or not every cell was handled with IFNα1/IFNβ or PBS, and the accuracy of the prediction was represented as receiver working traits curves (Prolonged Information Fig. 2c). The ISGs had been obtained from the MSigDB hallmark gene set.

Differential gene expression evaluation

Analyses of DEGs had been carried out to establish marker genes for cell clusters or cytokine-responsive genes. Analyses of DEGs had been carried out between two teams of cells utilizing the two-sided Wilcoxon rank-sum take a look at on normalized gene expression values. The P values obtained from the exams had been then adjusted (Bonferroni or FDR) to handle a number of testing. Genes had been thought of DEGs within the cytokine signature if they’d FDR < 0.05 and absolute log₂(FC) > 0.25 between cytokine-treated and PBS-treated cells of the identical cell kind, had been expressed in >10% of cytokine-treated cells for upregulated genes or >10% of PBS-treated cells for downregulated genes, and happy the FC threshold for no less than two out of the three mice (to mitigate the affect of potential single-mouse outliers). Rps, Rpl, mitochondrial genes and unlabelled genes had been excluded from the signatures. Cell-type-specific cytokine signatures are listed for all main cell sorts in Supplementary Desk 3.

Quantification of general magnitude of transcriptomic responses to every cytokine in every cell kind

We constructed a world reference map that quantified the general gene expression modifications induced by every cytokine in every cell kind (Fig. 1d). This maps takes into consideration two metrics: the variety of DEGs and the magnitude of change throughout the whole transcriptome. The variety of DEGs is the full variety of genes in every cytokine signature. The general magnitude of cytokine-induced differential expression was computed because the Euclidean distance between the centroid vectors of cytokine-treated cells and PBS-treated cells. This worth was normalized to a scale starting from 0 (low) to 100 (excessive). To cut back the influence of outliers within the normalization course of, winsorization was utilized such that values above the ninety fifth percentile had been changed with values on the ninety fifth percentile earlier than normalization. A most of 100 cells from every cytokine therapy situation had been sampled for every cell kind for the magnitude calculation. A definite color ramp was used for every cell kind to emphasise that cell sorts have totally different properties (for instance, totally different variety of genes expressed on common) and had been independently analysed. Cytokine–cell kind combos with 5 or extra cells sampled had been included on this evaluation.

Identification of GPs per cytokine therapy and per cell kind

GP evaluation was used to establish co-regulated genes for every cytokine therapy throughout cell sorts (Fig. 2c and Supplementary Fig. 1) or for every cell kind throughout all therapy situations (Prolonged Information Figs. 5i,j, 6i,j, 7i,j and 8i,j and Supplementary Figs. 2i,j, 3i,j, 4i,j, 5i,j, 6i,j, 7i,j, 8i,j, 9i,j, 10i,j and 11i,j). GPs had been constructed utilizing the non-negative matrix factorization (NMF) algorithm⁴⁴ utilizing the R bundle NMFN (v.2.0). We eliminated genes related to tissue dissociation⁴⁵ and the cell cycle, in addition to mitochondrial genes, Rps and Rpl, unlabelled genes, globally overabundant genes and people expressed in fewer than ten cells.

Within the cytokine-centric evaluation, NMF was used to establish cell-type-specific GPs in response to every cytokine. Cells handled with the required cytokines or PBS had been used for NMF, with a most of 100 cells per cell kind per situation. NMF was run individually for every cytokine on this evaluation, besides that IFNα1 and IFNβ had been processed collectively and IL-1α and IL-1β had been processed collectively in Fig. 2c and Supplementary Desk 5. We recognized 40 GPs per cytokine therapy, with some predominantly comparable to cell-type identification and others predominantly to mobile responses to cytokine stimulation. To quantitatively establish GPs predominantly comparable to mobile responses to cytokine stimulation, a two-sided Wilcoxon rank-sum take a look at was used to establish GPs with weights that had been considerably totally different between the cytokine-treated cells and PBS-treated cells. GPs exhibiting vital upregulation in any cell sorts had been displayed. The highest 30 genes with the best weights for every GP had been used to establish enriched organic processes utilizing clusterProfiler (v.4.2.1)⁴⁶ on the Hallmark gene units from the MSigDB database⁴⁷. Genes highlighted within the textual content for organic significance happy two standards: (1) they had been among the many prime 30 highest-weighted genes for a considerably upregulated GP in response to cytokines; and (2) the genes individually additionally confirmed vital upregulation in response to cytokines within the DEG evaluation of cytokine signatures.

Within the cell-type-centric evaluation, NMF was used to analyse GPs of every cell kind throughout all cytokine therapy situations to establish cytokines that induce related mobile processes. We recognized ten GPs for every cell kind and visualized the connection between GPs and subclusters for every cell kind utilizing heatmaps in Prolonged Information Fig. 5–8 and Supplementary Figs. 2–11. The highest genes with the best weights for every GP are proven in Prolonged Information Figs. 5j, 6j, 7j and 8j, Supplementary Figs. 2j, 3j, 4j, 5j, 6j, 7j, 8j, 9j, 10j and 11j and Supplementary Desk 8.

Evaluation of secondary responses to induced IFNγ

The IFNγ-induced gene expression signature was used to deduce the extent of mobile responses to cytokine-induced IFNγ. The IFNγ signature rating for every cell kind was constructed by summing the expressions of considerably overexpressed genes in IFNγ-treated cells relative to PBS-treated cells (FDR-adjusted P < 0.001 and log₂(FC) > 1) within the corresponding cell kind. The log₂(FC) of the signature scores and FDR-adjusted P worth relative to PBS-treated cells had been calculated for each cytokine therapy and proven in Prolonged Information Fig. 4e.

Identification of mobile polarization states

To establish mobile polarization states induced by cytokines, subclustering was carried out for cells of every cell kind. For heterogeneous cell sorts (for instance, macrophage, MigDC and γδ T cell), probably the most ample homogeneous subset was analysed to establish cytokine-induced states as a substitute of re-deriving cell subsets within the polarization state evaluation. We used PCs to subcluster on the premise of discriminating genes, outlined as genes with a big absolute log₂(FC) (between 0.75 and 1.5 relying on cell kind) in any cytokine-treated cells in contrast with PBS-treated cells. We eliminated genes related to tissue dissociation⁴⁵ and the cell cycle, in addition to mitochondrial genes and Rps and Rpl. We then carried out PCA and visualized the cells utilizing UMAP⁴⁸. The proportion of cells falling into every cluster was calculated for every cytokine or PBS management. Main polarization states had been recognized on foundation of two standards: (1) cell clusters with considerably (FDR-adjusted P < 0.01) greater than the anticipated variety of cytokine-stimulated cells utilizing a hypergeometric take a look at; and (2) guide verification of organic relevance of the extremely expressed genes or GPs within the subcluster and cytokines inducing the modifications. To search out discriminating markers and organic features of every state, we analysed DEGs and co-regulated GPs per state relative to all different cells for the cell kind. DEGs had been recognized utilizing the two-sided Wilcoxon rank-sum take a look at between every polarization state and different cells of the identical cell kind. The considerably overexpressed genes with the most important log₂(FC) are proven. Essentially the most strongly polarized states are summarized in Fig. 3. The whole panorama, together with less-strongly polarized states, in every cell kind will be present in Prolonged Information Figs. 5–8 and Supplementary Figs. 2–11. We in contrast the polarization states by calculating the pairwise Pearson correlation coefficients between the gene expression profiles of every polarization state after subtracting the profiles of PBS-treated cells of the identical cell kind to take away cell-type-specific gene expression. These outcomes are displayed in Prolonged Information Figs. 5b, 6b, 7b and 8b and Supplementary Figs. 2b, 3b, 4b, 5b, 6b, 7b, 8b, 9b, 10b and 11b.

We assigned a singular identifier to every polarization state utilizing the next conference: ‘<cell kind abbreviation>-<decrease case letters>’. When relevant, the letters a–d had been reserved for kind I interferon, kind II interferon, IL-1α and IL-1β, and TNF, respectively, that are cytokines that induce polarization states throughout numerous cell sorts.

Comparative international view of polarization states throughout immune cell sorts

To achieve a world view of the 66 polarization states throughout immune cell sorts outlined in Fig. 3, we used Jaccard similarity index to judge similarity between every pair of cell states (Prolonged Information Fig. 9). The gene expression profile of every polarization state was in contrast with PBS-treated cells of the identical cell kind to take away cell-type-specific gene expression. The genes with an absolute log₂(FC) > 0.5 in contrast with PBS-treated cells had been used to compute the Jaccard similarity rating. Upregulated and downregulated genes had been individually calculated. The rows and columns had been hierarchically clustered utilizing the average-linkage technique on the Euclidean distances to establish teams of comparable polarization states. To visualise distinctive polarization states with low similarity to different states, the identical outcomes had been illustrated utilizing a force-directed community, with a better circle dimension indicating a extra distinctive state, which was calculated on the premise of the inverse of imply Jaccard similarity worth with different states.

Pathway enrichment evaluation for NK cells

To establish organic processes enriched for the IL-18-treated NK cells, a pre-ranked gene checklist was computed by subtracting common gene expression values of PBS-treated NK cells from these in IL-18-treated NK cells. Gene set enrichment evaluation was carried out utilizing clusterProfiler (v.4.2.1) on the gene ontology organic processes gene units. Gene units with a FDR-adjusted P < 0.1 are proven. As a comparability, consultant cytokines from different NK cell polarization states had been analysed utilizing the identical technique.

Cytokine and cytokine–receptor gene expression maps

A map of cell-type-specific manufacturing of cytokines was derived from our dataset. Cytokine genes expressed in no less than 50 cells had been included within the cytokine expression heatmap. The cells had been obtained from all situations (PBS or cytokine handled) to offer a map of cytokine expression below all unstimulated or cytokine stimulation situations (that’s, to account for induced expression). The gene expression stage was then normalized relative to the cell kind with the utmost expression stage (whereby the utmost stage is capped at 1 expression unit earlier than normalization) to account for the variation within the variety of transcripts produced or detected for every cytokine. A cytokine was thought of expressed in a cell kind if greater than 0.1 normalized expression items had been detected.

The cytokine–receptor expression map was constructed utilizing the identical strategy. This included signalling receptors, decoy receptors and receptors that type complexes with cytokines. An inventory of genes encoding recognized practical receptors for the 86 studied cytokines are listed in Supplementary Desk 1. The cytokine expression map and the cytokine–receptor expression map are proven in Fig. 4a, Prolonged Information Fig. 10c and Supplementary Desk 9.

Cell–cell interactome community development

A cell–cell interactome community was constructed to chart accessible cytokine-mediated cell–cell communication channels. The community was constructed such that the supply and sink nodes are cell sorts and intermediate nodes are cytokines. The paths between supply cell-type nodes and sink cell-type nodes by cytokine nodes had been established on the premise of the detectability of the cytokine mRNA within the cell inhabitants (normalized expression > 0.1) and the responsiveness of the cell kind to the cytokine (greater than ten DEGs within the corresponding cytokine signature). For heteromeric cytokines or cytokine complexes composed of two subunits (IL-12, IL-23, IL-27, LTα1/β2 and LTα2/β1), the cytokine is proven as expressed and is annotated with an asterisk if the genes encoding no less than one subunit are expressed as there’s proof of extracellular meeting of some parts into practical cytokines below wholesome or pathological situations⁴⁹. The community was plotted individually for every supply node for ease of interpretability.

To assemble the ligand–receptor interactome, we recognized practical cognate receptors for every cytokine from the literature, which is listed in Supplementary Desk 1. For a receptor to be thought of expressed in a cell kind, the normalized expression worth of the receptor gene wanted to be better than a cut-off threshold (default of 0.1 expression unit). For heteromeric receptors, all parts wanted to be expressed for the receptor to be thought of expressed. For cytokines with a couple of practical receptor, the receptor was thought of expressed if any practical receptors are expressed. We then related the cytokines with the cell sorts expressing the cognate receptors. The cytokine manufacturing portion of the interactome is identical because the one within the ligand–response interactome. The ligand–response and ligand–receptor networks had been then in comparison with generate the cell–cell communication paths which might be frequent or totally different between these two approaches.

Enrichment will also be calculated utilizing the hypergeometric take a look at on vital DEGs (FDR < 0.01 between cytokine-treated cells and PBS-treated cells), a way generally utilized in pathway analyses.

2. 2.

   For the gene expression matrix enter, the expression matrices are first normalized such that the full expression per cell sums to 10,000 items; the expression is then log-transformed. Genes giving vital contribution to the enrichment rating, with the default being these having a median of greater than 0.25 expression values, had been included. Subsequent, the projection rating is calculated by discovering the cosine similarity rating between consumer enter and cytokine-treated or PBS-treated cells. Statistical significance is assessed utilizing a two-sided Wilcoxon rank-sum take a look at between projection scores on cytokine-treated cells and projection scores on PBS-treated cells, and an FDR correction is utilized to all cytokine calculations. The impact dimension is the imply distinction between projection scores on cytokine-treated cells and on PBS-treated cells. The impact dimension and FDR-adjusted P worth for every of the 86 cytokines can then be visualized utilizing a compass plot proven in Fig. 5d. Conceptually, this technique takes into consideration the route and magnitude of expression of every gene. That’s, a strongly upregulated gene in each the consumer dataset and Immune Dictionary reference dataset is given a excessive weight that will increase the general chance of enrichment; a strongly upregulated gene in a single dataset however not the opposite is given decrease weight; and a gene that’s upregulated in a single dataset however downregulated within the different is given unfavourable weight that decreases the general chance of enrichment. The genes contributing the best weights to the enrichment will be visualized utilizing a diverging bar plot proven in Prolonged Information Fig. 12b.

IREA for mobile polarization evaluation

IREA polarization evaluation implements the identical statistical take a look at because the IREA cytokine response evaluation. In IREA polarization, consumer knowledge are in contrast with the polarization state gene expression profiles. A polarized radar plot is proven if no less than one mobile polarization state is considerably enriched (FDR-adjusted P < 0.05). If no state is considerably enriched, the radar plot reveals an enrichment rating of 0 for each state, which signifies that the enter cells are unpolarized. The enrichment rating is normalized to be between 0 and 1 on the radar plot.

IREA for cell–cell communication community development

We constructed fashions of cell–cell communication networks by taking into consideration cytokine manufacturing and cytokine response. Cytokine manufacturing was obtained by analyzing the transcripts mapped to every of the 86 cytokines. The cytokine response was assessed utilizing IREA, and cytokines with IREA output of FDR < 0.01 had been included. For heteromeric cytokines or cytokine complexes composed of two subunits, the cytokine was displayed as expressed if no less than one subunit is expressed as there’s proof of extracellular meeting of some parts into practical cytokines⁴⁹ (similar technique as for the cell–cell interactome). Cytokine networks will be visualized as proven in Fig. 5e and Prolonged Information Fig. 12c.

IREA evaluation of mouse tumour scRNA-seq knowledge
