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
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

Research in Italy, in the coming years, will suffer much more compared to research in other countries, because, explained a study on the future of biomedical research in Italy described yesterday in Siena by Stefano Palumbo, “the national debate on bioethical issues will continue to be affected by pre-established ideological positions, and often, will be aimed at imposing limits on scientific research”.
Due to the overwhelming “majority of Catholic members in the National Bioethics Committee, Italy will be,” according to the study, “the most conservative country in the world regarding stem cells,” which will result in
As Aaditya watches a cartoon show on television, his right hand wavering to caress soft toys (SpongeBob SquarePants and Noddy) tucked next to him in bed, the boy has no clue that researchers and doctors across the world are watching his recovery with bated breath.
That’s because this frail boy, who is set to turn eight next month, is the first ever to receive a stem cell transplant for a rare and destructive illness — called Childhood Alzheimer’s (medical term: Niemann-Pick Type C or NPC), which causes neurological degeneration and seizures — for which there is no conventional treatment. Stem
Researchers believe that they can produce new eggs in infertile women even if the ovaries are damaged or the woman has passed the usual age of conception.
The technique involves transplanting stem cells into the ovaries and could work on the one in 10 women who suffer from infertility as well as those who want children late in life.
Until recently it was assumed that a woman was born with a finite lifetime store of around two million egg-producing follicles and no more could be produced.
By puberty this number has already fallen to about 400,000, and at the menopause too few
