Figure 2. Resveratrol promoted axonal regeneration after SCI. (A) Histological changes were evaluated using HE staining; (B) The expression of GAP43 was measured using IHC staining; (C) The expression of NF421 was measured using IHC staining; (D) The expression of GFAP was measured using IHC staining; (E) The levels of GAP43, NF421, and GFAP were analyzed. *P <0.05 compared with group SCI. The experiments were repeated at least 3 independent times.
