One of the major causes of hearing loss in mammals is damage to the sound-sensing hair cells in the inner ear. For years, scientists have thought that these cells are not replaced once they're lost, but new research appearing online February 20 in the journal Stem Cell Reports reveals that supporting cells in the ear can turn into hair cells in newborn mice. If the findings can be applied to older animals, they may lead to ways to help stimulate cell replacement in adults and to the design of new treatment strategies for people suffering from deafness due to hair cell loss.
