Scientists At Johns Hopkins are studying the molecular mechanisms that information the formation of hair cells. Scientific studies for instance these could possibly be a action in the direction of fewer invasive therapies for deafness in which molecular cues may be used to biologically regenerate hair cells in the cochlea. https://www.google.com/maps/d/edit?mid=1GFEya8412VFKj7VLxU7wy4fFPXFNHF0&usp=sharing
