In an exciting development in the treatment of spinal cord injuries, researchers at Cambridge University were able to restore some movement to the legs of dogs who had been paralyzed . (All 34 dogs in the study had become paralyzed by injuries or accidents. No dog was purposely injured for the research.)
The breaks in the spinal cord were at least partially fixed with the use of cells from the dogs’ own noses. The specific type of cells that they used, olfactory ensheathing cells (OECs), are involved in the growth of nerve fibers that are necessary for communication between the brain and the nose.
Dogs who were treated with OECs showed significant improvement in the movement of their back legs compared with the control group, which did not receive OECs. Being able to walk again obviously has considerable quality-of-life benefits. Researchers point out that this procedure will probably be most effective if combined with other therapies, such as drugs and physical therapy.
Though it is likely a long way off, similar therapies may eventually be effective in treating people with paralysis because of spinal cord injuries.
