What is Spinal Cord Injury?What is Spinal Cord Injury? Spinal cord: bundle of nerves which run through the spine Damages/injuries cause: loss of sensory input & voluntary/involuntary functions Two Types of spinal cord injuries: Traumatic spinal cord injury Non-traumatic spinal cord injury

Autologous olfactory mucosal cell transplants in clinical spinal cord injury: a randomized double- blinded trial in a canine translational model Nicolas Granger, Helen Blamires, Robin J. M. Franklin and Nick D. Jeffery Hypothesis: If olfactory mucosal cells (OMC) are transplanted into the spine of a canine with spinal cord injury, then there should be improved fore-hind limb coordination/movement Purpose: To use olfactory mucosal cells as a prospective therapy for spinal cord injuries Model: Dogs with spinal cord injuries

Granger et al, 2012
Results Significant data from primary measures, but not from secondary measures Subjects who received mucosal cell transplant regained some fore-hind coordination/movement Coordination and movement ≠ restoration of brain control Coordination may be due to enhanced communication across damaged region of spinal cord Implies long tract axon improvement, however data suggests otherwise
Hopes for Humans? Humans with spinal cord injury want the recovery of: 1.Arm function 2.Bladder function 3.Sexual function Olfactory mucosal cell transplant would result in some improvement Should not be the sole treatment Transplantation is not the safest for humans
