KANSAS CITY, MO One of the evolutionary disadvantages for mammals, relative to other vertebrates like fish and chickens, is the inability to regenerate sensory hair cells. The inner hair cells in our ears are responsible for transforming sound vibrations and gravitational forces into electrical signals, which we need to detect sound and maintain balance and spatial orientation. Certain insults, such as exposure to noise, antibiotics, or age, cause inner ear hair cells to die off, which leads to hearing loss and vestibular defects, a condition reported by 15% of the US adult population. In addition, the ion composition of the fluid surrounding the hair cells needs to be tightly controlled, otherwise hair cell function is compromised as observed in Ménière s disease.
