Cell transplant enables paralysed dog to walk

Scientists in Cambridge have enabled paralysed dogs to walk again by injecting them with cells taken from inside their noses.

The pets had all suffered spinal injuries which prevented them from using their back legs.

The researchers say the transplanted cells from the nose regenerated nerve-fibres across the damaged region of the spinal cord.

This enabled the dogs to regain the use of their back legs and coordinate movement with their front limbs.
