Generation of Inner Ear Hair Cells by Direct Lineage Conversion of Primary Somatic Cells [ATAC-seq]

We purified seven different cell populations and performed RNA sequencing to profile transcriptional similarities and differences between them. The seven cell types were 1) Atoh1-GFP positive cochlear hair cells from the organ of Corti of postnatal day one mice, 2) Atoh1-GFP negative cells from the organ of Corti of postnatal day one mice, 3) Atoh1-GFP positive induced hair cells generated by overexpression of Six1, Atoh1, Pou4f3, and Gfi1, 4) dsRed transduced control mouse embryonic fibroblasts, 5) Atoh1-GFP positive Merkel cells from postnatal day 1 mice, 6) Atoh1-GFP positive Cerebellar granule precursor cells from postnatal day 1 mice, and 7) Atoh1-GFP positive Gut secretory cells from postnatal day one mice. Compare chromatin accessibility of induced hair cells generated by direct reprogramming of mouse embryonic fibroblasts to control mouse embryonic fibroblasts and primary P1 cochlear hair cells.
