Gene therapy for hair cell regeneration: Review and new data

Hair cells (HCs) in the cochlea are responsible for transducing mechanical sound energy into neural impulses which lead to the perception of sound. Loss of these sensory cells is the most common cause of sensorineural hearing loss, and spontaneous HC regeneration does not occur in mature mammals. Among the future potential treatment modalities is gene therapy, which is defined as the administration of either DNAs or RNAs as active pharmaceutical...
