Stem cell transplants explored at Stanford as a possible treatment for hearing loss

...y of those with hearing loss, particularly in the aging population, drug therapy could be the solution. As the population has aged and noise pollution has grown more severe, health experts now estimate that one in three adults over the age of 65 has developed a handicapping hearing loss. Coming up w...
