Twenty-five adult mongrel dogs were assigned to five groups according to treatment after a spinal cord injury no treatment CN saline treatment CP rmhGCSF treatment G UCB-MSCs treatment UCB MSC co-treatment UCBG . The UCB-MSCs isolated from cord blood of canine fetuses were prepared as 106 cells 150 pl saline. The UCB-MSCs were directly injected into the injured site of the spinal cord and rmhGCSF was administered subcutaneously 1 week after the induction of spinal cord injury. The Olby score magnetic resonance imaging somatosensory evoked potentials and histopathological examinations were used to evaluate the functional recovery after transplantation. The Olby scores of all groups were zero at the 0-week evaluation. At 2 week after the transplantation the Olby scores in the groups with the UCB-MSC and UCBG were significantly higher than in the CN and CP groups. However there were no significant differences between the UCB-MSC and UCBG groups and between the CN and CP groups. These comparisons remained stable at 4 and 8 week after transplantation. There was significant .
