B. The protein expressions of GAP43 in sham, SCI rats and SCI rats treated with NGF groups. GAPDH was used as the loading control and for band density normalization. C. The optical density analysis of GAP43 protein. ** P < 0.01 versus the SCI group, and ### represents P < 0.005 versus the sham group. Data are the mean values ± SEM, n = 6

The effect of the nerve growth factor (NGF) group in promoting damage repair has not changed and the changes do not affect the scientific significance of current article.
