Notch inhibition induces cochlear hair cell regeneration and recovery of hearing after acoustic trauma.

Neuron · 2013

Pharmacological Notch inhibition converts cochlear supporting cells into new hair cells and partially restores hearing after noise trauma in mice.

Lgr5-positive supporting cells generate new hair cells in the postnatal cochlea.

Stem cell reports · 2014

Identifies Lgr5-expressing supporting cells as the specific source of newly generated hair cells after damage, and shows Notch inhibition boosts how many of them convert.
