Clinic claims stem cells treat Down's syndrome

摘要

A Clinic claims it has used stem cells to treat Down's syndrome in up to 14 people. "As far as we know, it's the first time that stem cells have been used to treat Down's syndrome," says Jyoti Titus, manager at Nutech Mediworld clinic in New Delhi, India. The announcement has set alarm bells ringing. It's not clear to independent stem cell or Down's experts how stem cells - which can form many types of tissue -might treat Down's, a genetic disorder caused by having an extra chromosome. "The use of these cells does not make biological sense and may place the babies at considerable risk of side effects,"says John Rasko of the International Society for Cellular Therapy.
