Funding provided by Hearing Health Foundation through the Hearing Restoration Project (HRP) has helped the development of a new research program in the laboratory of Stefan Heller, Ph.D., at Stanford University focusing on chicken hair cell regeneration. Several years after its inception, this research is now bearing fruit.
A Key Molecule Required for the Regeneration of Auditory Hair Cells in the Avian Inner Ear
Hair cells in the cochlea are the only cells in our body specialized to encode the energy in sound waves. As a result, we lose our hearing when hair cells die, which occurs during aging and after exposure to excessive noise or ototoxic drugs. Research indicates that no adult mammals replace their auditory hair cells once they are lost.
