A scientist at the University of Bristol, in the UK, have successfully engineered ear cells that could be transplanted into humans to prevent further hearing loss or even restore hearing in the deaf. Professor Matthew Holley, who carried out the work, believes the cells could be used in combination with existing cochlear implants, which work by stimulating the auditory nerve. Cochlear implants cannot be given to deaf people as their auditory nerves are badly degenerated, however Holley believes that used together the implants and the ear cell implants will promote nerve regeneration. Professor Holley estimates that the engineered ear cells could be ready for use within three to five years time.
