Hearing loss is primarily caused by damage to specialized cells (called hair cells) that detect sound waves traveling through the cochlea of the inner ear. Non-mammalian vertebrates, such as birds, fish, and amphibians, can regenerate their hair cells after damage, while damage to auditory hair cells in mammals is currently thought to be permanent. We have recently developed a genetic method to damage hair cells in the neonatal mouse in vivo and discovered that, in contrast to common belief, the mouse cochlea does have the capacity to regenerate its hair cells
