(E) Enrichment of astrocyte specific genes (from scRNA-seq) and genes bound by SOX3 and SOX9 in GPCs in the four different astrocyte gene clusters (A1-A4), shown in Fig. 3C. Three-star significance equals p-value e-13 (prop.test, R) based on the size of the gene groups (A1=740, A2=1019, A3=882, A4=1236) (F) Enrichment of oligodendrocyte specific genes (from scRNA-seq) and genes bound by SOX3 and SOX9 in the four different oligodendrocyte gene clusters (O1-O4), shown in Fig. 3D. Three-star significance equal p-value e-7 for cluster O3 and e-16 for cluster O4 (prop.test, R) based on the size of the gene groups (O1=1371, O2=1451, O3=839, O4=141)
