Figure 1: Effect of combination of myelin-associated glycoprotein and chitin conduit on autotomy behavior and NGF and α-SMA gene expression in proximal nerve stumps 8 weeks postoperatively. (A) Modified Wall Scale (n = 10 animals per group). The higher the score, the more severe the injury. (B, C) Relative mRNA expression levels of NGF (B) and α-SMA (C). The relative mRNA expression level (n = 5 animals per group) was normalized by GADPH. Data are expressed as the mean ± SD. ##P < 0.01, vs. model group; **P < 0.01, vs. conduit group (one-way analysis of variance followed by Tukey’s post hoc test). GADPH: Glyceraldehyde-3-phosphate dehydrogenase; NGF: nerve growth factor; α-SMA: alpha-smooth muscle actin.
