Success of sensory cell regeneration raises hope for hearing restoration

from Medical Xpress

In an apparent first, St. Jude Children's Research Hospital investigators have used genetic manipulation to regenerate auditory hair cells in adult mice. The research marks a possible advance in treatment of hearing loss in humans. The study appears today in the journal Cell Reports. Loss of auditory hair cells due to prolonged exposure to loud noise, accidents, illness, aging or medication is a leading cause of hearing loss and long-term disability in adults worldwide. Some childhood cancer survivors are also at risk because of hair cells damage due to certain chemotherapy agents. Treatment has focused on electronic devices like hearing aids or cochlear implants because once lost, human auditory hair cells do not grow back. more
