Recent developments in medical research have offered a number of advances that promise to eventually rid us of a number of chronic ailments and physical maladies. But one new experiment presents an even more exciting breakthrough that should offer hope to the paralyzed.
A team of scientists at the Regenerative Medicine Centre and Cambridge University's Veterinary School has managed to reverse paralysis in a dog's legs after injecting it with cells grown from the lining of its nose. Using olfactory ensheathing cells found in the back of the nose--the only nerve fibers that continue to grow in adults--the scientists were able to restore a small amount of movement to the back legs of dogs with spinal injuries. None of the dogs regained full use of their back legs, but many were able to walk with the assistance of a harness.
The scientists caution that this doesn't represent a cure for paralysis, but it does point toward future advances in treating such injuries in human patients. You can see Jasper the dachshund going from pre-treatment paralysis to post-treatment walking in the video below.
