Single cell were isolated from E16.5 backskin using Collagenase treatment, followed by trypsinization. K14-H2BGFP-positive epithelial cells and K14-H2BGFP-negative non-epithelial cells were sorted by FACS, and then re-combined at 5:1 ratio to enrich for epithelial cells. scATAC libraries were constructed following 10x Genomics single cell ATAC v1 protocol.
