USC Stem Cell study breaks the silence on how fish and lizards regenerate hearing

A USC Stem Cell study has identified key gene regulators that enable some deafened animals, including fish and lizards, to naturally regenerate their hearing. The researchers found a class of DNA control elements known as 'enhancers' that amplify the production of a protein called ATOH1, which induces sensory cells in the inner ear.
