Nose cell transplant enables paralysed dogs to walk
|
Scientists have reversed paralysis in dogs after injecting them with cells grown from the lining of their nose. The pets had all suffered spinal injuries which prevented them from using their back legs. The Cambridge University team is cautiously optimistic the technique could eventually have a role in the treatment of human patients. The study is the first to test the transplant in 'real-life' injuries rather than laboratory animals. Professor Robin Franklin, a regeneration biologist and report co-author, said: "Our findings are extremely exciting because they show for the first time that transplanting these types of cell into a severely damaged spinal cord can bring about significant improvement. "We're confident that the technique might be able to restore at least a small amount of movement in human patients with spinal cord injuries but that's a long way from saying they might be able to regain all lost function." Prof Franklin said the procedure might be used alongside drug treatments to promote nerve fibre regeneration and bioengineering to substitute damaged neural networks.
