Delineation of cell types in E18.5 cortex and identification of master regulators of the OBiN-lineage. A Seventeen clusters (C0-C16) identified and annotated according to marker gene accessibility (scATAC-seq was performed on GFP+ cells from the E18.5 cortex of hGFAP-GFP transgenic mice). B Genome tracks showing normalized accessibility for marker genes with cluster-specific accessibility in their promoter and gene body. C UMAP plots showing distinct chromatin accessibility profiles of marker genes. D Scheme for construction of the developmental trajectory. E Enrichment analysis for transcription factor motifs in the OBiN-lineage showing that GSX2 and DLX1/2 bind to the VISTA enhancers of Dlx1/2, Dlx5/6 and Sp8/9. The height of the letters (right panel) represents the frequency of each base in the cognate motif.
