There’s a medical breakthrough for the deaf.
Scientists at United Kingdom’s Sheffield University have created stem cells from embryos to replace damaged cells in the inner ear — reversing hearing loss.

The embryonic stem cells could be converted into workable hearing cells for people born with inherited hearing problems and who’ve suffered damage to their ear cells during their lifetime, according to the scientists.
The breakthrough stem-cell discovery is “incredibly promising” and “opens up exciting possibilities,” Dr. Ralph Holme, a biomedical researcher, told the British Broadcasting Corporation.

But the stem-cell research could be halted by critics who argue that the controversial process destroys embryos in the name of science – a debate that’s raged since stem-cell studies began years ago.
Earlier this year, President Barack Obama lifted the ban on embryonic stem-cell research, reinforcing the science world’s belief that studying embryonic cells is necessary for the development of new medical treatments.

Researchers at the University of Sheffield have created the complex hair cells and the neurons needed for hearing from human stem cells.
They found they could encourage stem cells from the inner ears of human foetuses to grow into these highly specialised hearing cells.
The scientists hope they will eventually be able to use the cells to perform cell transplants in deaf patients to replace the hair cells and neurons that are damaged in a form of deafness known as sensorineural hearing loss.
Sensorineural hearing loss one of the most common forms of deafness, accounting for 90 per cent of cases and affecting more than 6 million people.
