a UMAP representation of scATAC-seq for EGCs (686), ANCCs (964), cortical astrocytes (246) and cortical oligodendrocytes (214). b Dot plot showing GO terms overrepresented among genes with differentially accessible peaks (log2FC > 1 & padj <0.01) in promoter regions for ANCCs and EGCs. Dot size indicates the overlap for each term, and gene ratio indicates the fraction of genes in each term. c, d UMAPs (as in panel a) indicating SOX10 (c) and IRF1 (d) motif activity, calculated using Chromvar. e Volcano plots showing mean log2-transformed fold change (FC; x axis) and significance (−Log10(adjusted P value)) of differentially accessible (DA) genes from the indicated GMs between ANCCs and EGCs. f Bar plot showing the percentage of genes in the indicated GMs (x axis) that have at least one DA peak in their promoter region between ANCCs and EGCs. g Bar plot showing the statistical significance (hypergeometric test, −Log10(p-adj)) of enrichment of genes with at least one peak in their promoter region for the indicated GMs. Dashed line indicates p-adj = 0.01. h Track plots of ATAC signals for genes maintaining accessibility in EGCs relative to ANCCs (Phox2b, Zfhx3) and genes with reduced accessibility in EGCs relative to ANCCs (Hmga2, Igfbp2).
