Expression of neurotrophic factors between two groups. Protein bands of BDNF and GAP-43 in the ipsilateral L4–5 spinal cord were detected by western blot analysis (a). Quantification of protein levels of BDNF (b) and GAP-43 (c). NCSC group had significantly higher neurotrophic factors expression compared with the Scaffold group. *p < 0.05, **p < 0.01, N = 3
