Restoring Hearing: New Tool to Create Ear Hair Cells Lost Due to Aging or Noise
6th May 2022
Hearing loss caused by aging, noise, and some cancer therapy medications and antibiotics has been irreversible because scientists have not been able to reprogram existing cells to develop into the outer and inner ear sensory cells — essential for hearing — once they die.
But Northwestern Medicine scientists have discovered a single master gene that programs ear hair cells into either outer or inner ones, overcoming a major hurdle that had previously prevented the development of these cells to restore hearing, according to new research published today (May 4, 2022) in the journal Nature.
