Identification of a modular super-enhancer in murine retinal development

Single cell RNA-sequencing shows cell type specific expression of genes in the retina. Single cell ATAC-sequencing of the wild type retina at multiple stages revealed that chromatin in the Vsx2 CRC SE, a stage- and cell type-specific core regulatory circuit super-enhancer (CRC-SE) upstream of the Vsx2 gene, was only open in bipolar cells in Region3 in adult retina. Chromatin in Region0 was open in retinal progenitor cells in E14.5 retina. Single cell RNA sequencing, single cell ATAC sequencing, bulk RNA sequencing, and ChIP sequening from WT and VSX2SE Region deletion mice retina at E14.5 and adult stages
