LONDON, England -- British surgeons hope a new procedure using stem cells from the lining of the nose will help mend severed nerves of paralyzed patients and may one day allow them to walk again. Neuroscientist Geoffrey Raisman discovered 20 years ago that the cells responsible for sense of smell are good at renewing themselves. When these cells were injected into the spines of rats they appeared to help cure damage to the nervous system. Now Raisman hopes to transfer that technology to humans, working with patients in clinical trials at the National Hospital for Neurology and Neurosurgery in London early next year.
