(Outer Supporting Cell, NCI Thesaurus)
The researchers showed that Bmp7 promotes the development of low-frequency-sensing hair cells.
(Hearing different frequencies, NIH)
Long or repeated exposure to loud noises can damage and even destroy hair cells.
(Protein involved in hearing loss recovery, NIH)
When they bathed developing basilar papillas in a solution containing Bmp7, they found that all the hair cells—even those at the high-frequency end—developed characteristics of low-frequency-sensing hair cells.

Vibrations from sound waves cause these hair cells to move up and down and create an electrical signal that travels to the brain.
(Protein involved in hearing loss recovery, NIH)
Each of our roughly 16,000 hair cells is dedicated to a narrow frequency range.

A team led by Dr. Patricia White of the University of Rochester previously showed that a protein called Forkhead Box O3 (FOXO3) is expressed in both inner and outer hair cells.
(Protein involved in hearing loss recovery, NIH)
The basilar papilla in chickens, like the cochlea in mammals, has hair cells arranged along the length of a basilar membrane according to frequency.
(Hearing different frequencies, NIH)
Finally, the scientists found FOXO3 in cochlear hair cells from a human cadaver, supporting the idea that it may also play a role in human hearing.
(Protein involved in hearing loss recovery, NIH)
While this stepwise arrangement of hair cells on the basilar membrane—the tonotopic map—has been known for years, how the cells become ordered this way was unknown.
