Now hear this: Stanford researchers identify forerunners of inner-ear cells that enable hearing
Date:2/26/2013

STANFORD, Calif. Researchers at the Stanford University School of Medicine have identified a group of progenitor cells in the inner ear that can become the sensory hair cells and adjacent supporting cells that enable hearing. Studying these progenitor cells could someday lead to discoveries that help millions of Americans suffering from hearing loss due to damaged or impaired sensory hair cells.

"It's well known that, in mammals, these specialized sensory cells don't regenerate after damage," said Alan Cheng, MD, assistant professor of otolaryngology. (In contrast, birds and fish are much better equipped: They can regain their sensory cells after trauma caused by noise or certain drugs.) "Identifying the progenitor cells, and the cues that trigger them to become sensory cells, will allow us to better understand not just how the inner ear develops, but also how to devise new ways to treat hearing loss and deafness."

The research will be published online Feb. 26 in Development. Cheng is the senior author. Former medical student Taha Jan, MD, and postdoctoral scholar Renjie Chai, PhD, share lead authorship of the study. Roel Nusse, PhD, a professor of developmental biology, is a co-senior author of the research.

The inner ear is a highly specialized structure for gathering and transmitting vibrations in the air. The auditory compartment, called the cochlea, is a snail-shaped cavity that houses specialized cells with hair-like projections that sense vibration, much like seaweed waving in the ocean current. These hair cells are responsible for both hearing and balance, and are surrounded by supporting cells that are also critical for hearing.

Twenty percent of all Americans, and up to 33 percent of those ages 65-74, suffer from hearing loss. Hearing aids and, in severe cases, cochlear implants can be helpful for many people, but neither address the underlying cause: the loss of hair cells in the inner ear. Cheng and his
