A Bulgarian man who was paralyzed from the chest down in a knife attack can now walk with the aid of a frame after receiving pioneering transplant treatment using cells from his nose.

"We believe . . . this procedure is the breakthrough which, as it is further developed, will result in a historic change in the currently hopeless outlook for people disabled by spinal cord injury," said Geoffrey Raisman, a professor at University College London's (UCL) institute of neurology, who led the research.
