Research on the regrowth of cochlear cells may lead to medical treatments that restore hearing. Unlike birds and fish, humans and other mammals are generally incapable of regrowing the cells of the inner ear that convert sound into neural signals when those cells are damaged by age or disease. Researchers are making progress in gene therapy and stem-cell therapy that may allow the damaged cells to be regenerated.
