Summary:
Deep inside the ear, specialized cells called hair cells detect vibrations in the air and translate them into sound. Ten years ago, Stefan Heller, PhD, professor of otolaryngology at the Stanford University School of Medicine, came up with the idea that if you could create these cells in the laboratory from stem cells, it would go a long way toward helping scientists understand the molecular basis of hearing in order to develop better treatments for deafness.
After years of lab work, researchers in Heller’s lab report in the May 14 issue of Cell that they have found a way to develop mouse cells that look and act just like the animal’s inner-ear hair cells — the linchpin to our sense of hearing and balance — in a petri dish. If they can further perfect the recipe to generate hair cells in the millions, it could lead to significant scientific and clinical advances along the path to curing deafness in the future, they said.
