However, finding a cure for hearing loss using hair-cell regeneration is likely to be at least 20 years away, they say.
They also determined that hair-cell regeneration can result in improved hearing; in experiments, song birds that had grown new hair cells were able to resume singing their original songs with perfect pitch again.
And why some animals, even within the same species, are more vulnerable to hair-cell death, while others are more resistant to it, is a mystery.
"Birds and fish can regenerate their hair cells, and we've done it on frogs," said Dr. John House, president of the House Ear Institute, a nonprofit research group in Los Angeles, which is working on hair-cell regeneration.
Dr. Rubel’s and Dr. Raible’s teams also are studying the genetics of zebrafish to identify markers that confer hair-cell protection.
Other researchers, like those at the University of Washington, are focused on understanding the molecules and genetics involved with hair-cell regeneration, and how to mimic this process in animals that don’t spontaneously regenerate hair cells.
