What about hearing?
This is very promising.
The researchers recovver 80% of the rats hearing.
It is very positive. We could get the treatment in 10 to 20 years while they
may tak 5-10 years for the test in human.
Clinical trials there are further off, but hope has been growing for years that researchers might find a way to regrow the delicate hair cells inside the inner ear. Humans are born with about 10,000 to 20,000 of these sensory cells, but we lose them as we age and they don't replenish themselves in people the way they do in birds. At UC Davis, tests have been done on lab rats to try to get stem cells to the right part of the ear for growing new hair cells, and to ensure that the new growth interacts properly with nerves. Researchers have restored hearing in about 80 percent of the rats they worked on, and they hope to try the procedure soon on nonhuman primates. If it's successful, it could be tested in humans in five to 10 years.
