Hearing loss is usually irreversible because there's no way to grow back the necessary outer and inner ear sensory cells once they've been killed off. But we may have started on the path to change, thanks to new research in mice.
Scientists have discovered a single master gene that's able to regulate whether ear hair cells into the outer or inner types required to restore hearing. That's a significant step forward in being able to actually carry this out in the lab.
from Northwestern University in Chicago."It will provide a previously unavailable tool to make an inner or outer hair cell. We have overcome a major hurdle." As sound waves hit the ear, the outer hair cells expand and contract in response to the pressure – the sound is then amplified for the inner hair cells, which transmit the vibrations into signals to the brain.
