Expression of VEGF and BDNF 28 days following spinal cord injury. Protein expression levels were determined through (A) western blotting followed by (B) analysis. Expression levels were normalized to GAPDH. Results are presented as the mean ± standard deviation. *P<0.05 vs. control; †P<0.05 vs. Control, ¥P<0.05 vs. BMSC group. VEGF, vascular endothelial growth factor; BDNF, brain derived neurotrophic factor; BMSC, bone marrow mesenchymal stem cell; EPO, erythropoietin.
