Dramatic stem cell research heals paralysed dog

Three years ago a Dachshund dog could not walk all when a slipped disc damaged his spinal cord and left him paraplegic. He was in a lot of pain and dragged his legs flat along the floor behind him.

But now, scientists have used a novel technique to treat him - they took special cells from his nose and injected them into his spine.The results were dramatic.
