Expression of enhanced green fluorescent protein (EGFP; green fluorescence) in the bone marrow mesenchymal stem cells (BMSCs) transplanted into the injured spinal cord at 4 weeks after transplantation (fluorescence microscope, × 200).
EGFP expression was significantly greater in the BMSCs + neurotrophin-3 group (C) than in the spinal cord injury (A) and BMSCs groups (B). The expression was lowest in the spinal cord injury group.
