<unk>  is the biological process by which the hair cells and supporting cells (i.e. Hensen's cells and Deiters cells) of the<unk>  proliferate (cell proliferation) and regrow after hair cell injury. This process depends on communication between supporting cells and the brain. Because of the volatility of the<unk> <unk> 's hair cells, regeneration is crucial to the functioning of the<unk> <unk> . It is also a limited process, which contributes to the irreversibility of hearing loss in humans and other mammals.
