To date, experimental induction of hair cell regeneration in mammals leads to immature and poorly differentiated hair cells. Here the authors show that the transcription factor prdm1a plays a crucial role in specifying sensory hair cell types with loss of prdm1a in zebrafish leading to misspecification of hair cells in the sensory lateral line system into ear hair cells.
