writes "Scientists from the University of Cambridge’s Veterinary School, working with colleagues from the UK Medical Research Council’s Regenerative Medicine Centre, have got disabled dogs walking again. More specifically, they’ve used the dogs’ own cells to repair their spinal cord injuries, and at least partially restored the functionality of their back legs. The researchers believe that the process shows promise for use on physically challenged humans.
The cells in question are known as olfactory ensheathing cells (OECs), and they aid in growing the nerve fibers that allow the nose to communicate with the brain. One of the more unusual qualities of the mammalian olfactory system is its ability to regenerate itself throughout adulthood – this is due to the activity of the OECs."Link to Original Source
