For a while now, scientists have been trying to come up with a way to restore hearing in mammals before it can be applied to humans. Well, apparently earlier this month the researchers at Harvard Medical School have for the first time demonstrated hair cels being regenerated in an adult mouse. They used a drug, with a protein called Notch, to stimulate resident cells to become new hair cells in the mouse’s ear after it was damaged by noise trauma.
“The missing hair cells had been replaced by new hair cells after the drug treatment, and analysis of their location allowed us to correlate the improvement in hearing to the areas where the hair cells were replaced,” Dr. Edge said.
It won’t be long before therapeutic application can reverse deafness in humans.
When the day comes and you were given the option to remain deaf or reverse it, which would you choose and why?
