Extended Data Fig. 4: Transcriptional analysis of Gli1- vs Ascl1-targeted cells.
From: Long-term self-renewing stem cells in the adult mouse hippocampus identified by intravital imaging
a, Representative FACS plots showing gating for live (Hoechst-) tdTomato+ DG cells sorted for scRNA-seq. b, t-Distributed Stochastic Neighbor Embedding (t-SNE) visualization of the 4 clusters (non-dividing NSCs (ndNSCs), dividing NSCs (dNSCs), Immature Neurons (IN), Mature Neurons (MN)) identified in Gli1- and Ascl1 targeted tdTomato+ neuronal cells. c, Uniform Manifold Approximation and Projection (UMAP) visualization of the seven individual datasets used for analysis. _1 and _2 indicate duplicates for a given data point. d, UMAP visualization of the cell isolated 5 days or 12 weeks after tamoxifen injection. e, Distribution of the cells among the 4 clusters, 5 days or 12 weeks after tamoxifen injection. f, Expression pattern of Ascl1 mRNA. g, Violin plots showing Ascl1 mRNA levels in Gli1- and Ascl1-derived ndNSCs and dNSCs (Wilcoxon text, *p < 0.05). h, Position of Gli1 (red) and Ascl1 (blue) ndNSCs and dNSCs along the pseudotime axis as calculated by Monocle. Cells present along the full pseudotime range (grey rectangle) or sharing the same pseudotime range (green rectangle) are depicted. i-j, Volcano plots showing significantly differentially expressed genes (DEGs) (red, padj < 0.05) between Gli1 or Ascl1-targeted ndNSCs (i) or dNSCs (j) when comparing only cells with shared pseudotime range. Venn diagrams indicate the overlap between DEGs found when comparing Gli1 or Ascl1-targeted ndNSCs (i) or dNSCs (j) using the full pseudotime range (grey circles) or the shared pseudotime range (green circles). Among the top 10 DEGs, bolded gene names highlight the DEGs found in both comparisons. k, UMAP visualization of RNA velocities calculated using scVelo.
