Olfactory Cells Restore Mobility on Paralyzed Dogs

A team of researchers from Cambridge University has been able to transplant olfactory ensheathing cells into the injured part of the spinal cords of dogs for the first time and restore some of the movement to their back legs.

Walking Again

The scientists used 34 dogs that had suffered trauma to their spinal cords and were unable to use their back legs. Olfactory cells from 23 of the dogs were removed from the lining of their noses and grown and expanded in the laboratory. The cells were then transplanted directly into the injury site. The rest of the dogs were just injected with a neutral fluid.

According to, many of the 23 dogs showed considerable improvement and were able to walk again on a treadmill with the support of a harness. On the other hand, none of the dogs in the support group regained any mobility in their back legs.

Professor Robin Franklin, a regeneration biologist at the Wellcome Trust-MRC Stem Cell Institute and co-author of this study has stated that the results of the experiment were “extremely exciting” because they show for the first time that transplanting these cells into a severely damaged spinal cord (in the real world, not in a lab) can bring about significant improvement. Dr. Franklin continued saying that although the team is confident that the procedure can help restore at least a small amount of movement in human patients with spinal cord injuries, they are note saying that it will restore all lost function.

Not Full Recovery For Humans

While the transplanted olfactory ensheathing cells can help regenerate nerves around the damages area of the spinal cord, they cannot help repair the nerve connections over long distances, like those that would allow the brain to connect with the spinal cord. This means that while it could enable some recovery of limb motion, it would not help with the recovery of control over sexual function, bladder function, hand function, temperature regulation, etc.

Long Rehabilitation Process

Therefore, victims of spinal cord injuries will continue to face a long and expensive specialized rehabilitation process, which is why those who have been the victims of a car accident, a motorcycle accident, a tractor-trailer accident, an amusement park accident or any other kind of accident caused by someone else’s negligence need the help of an experienced lawyer that can get them the funds they need for their rehabilitation therapy, as well as for their daily survival. It is very important that these victims (or their families) hire a lawyer quickly and allow this lawyer to begin working on their case immediately. Their attorney will then be in a position to do the same thing the attorneys for their opponents’ insurance companies are doing from the moment of the accident: preserving evidence and speaking with potential witnesses while the incident is fresh in their minds.
