Loss of Zbtb20 disrupts cochlear supporting cell differentiation and maturation and extends the postnatal hair cell regenerative window in mice.
Cochlear hair cell (HC) loss is a leading cause of hearing loss in humans. HCs can be generated from adjacent supporting cells (SCs); however, this regenerative capacity is lost after the onset of hearing. Using Emx2Cre Zbtb20 knockout mice, we show that ZBTB20 deficiency delays cell-cycle exit, differentiation, and maturation of cochlear SCs. Transcriptomic analysis of postnatal cochlear sensory…
