PARIS (AFP) – Scientists have used gene therapy on mouse embryos to grow hair cells with the potential to reduce hearing loss in adult animals, according to a study released Wednesday.

The proof-of-concept experiments are a crucial step toward therapies that could one day treat deafness and inner-ear disease in humans, said the study, published in the British journal Nature.

Sensory hair cells inside the cochlea, the auditory portion of the inner ear, convert sound waves into electrical impulses that are delivered to the brain.
BUDI = BUDEK DIKIT = HL = Hearing Loss = Kurang Pendengaran
The loss of these cells and the neurons they contain is the most common cause of hearing impairment and so-called nerve deafness.

At birth, humans have about 30,000 hair cells, which can be damaged by infections, ageing, genetic diseases, loud noise or treatment with certain drugs.

In most cases, damaged hair cells do not regrow in mature humans. But recent research has kindled hope that nerve deafness may one day be curable.

A team of scientists led by John Brigande at the Oregon Health and Science University, in Portland showed that implanting a gene known as Atoh1 into the inner ear of a mouse embryo coaxed non-sensory cells to become hair cells.
