The aim of this study was to observe the effects of bone marrow mesenchymal stem-cell transplantation (BMSCs) in repairing acute spinal cord damage in rats and to examine the potential beneficial effects. 192 Wistar rats were randomized into 8 groups. Spinal cord injury was created. Behavior and limb functions were scored. Repairing effects of BMSCs transplantation was evaluated and compared. In vitro 4’,6-diamidino-2-phenylindole (DAPI)-tagged BMSCs were observed, and whether they migrated to the area of spinal cord injury after intravenous tail injection was investigated. The expression of neuron-specific protein (NSE) on BMSCs was examined. Fifteen days after transplantation, the BMSCs-treated groups scored significantly higher in limb function tests than the untreated group. Pathological sections of the bone marrow after operation showed significant recovery in treated groups in comparison to the control group. After transplantation, small amounts of fluorescent-tagged BMSCs can be found in the blood vessels in the area of spinal cord injury, and fluorescent-tagged BMSCs were diffused in extravascular tissues, whereas the DAPI-tagged BMSCs could not be detected,and BrdU/NSE double-labeled cells were found in the injured marrow. BMSCs improve behavioral responses and can repair spinal cord injuries by migrating to the injured area, where they can differentiate into neurons. © 2015, E-Century Publishing Corporation.
