Comparison of the NF-200-positive areas detected by IHC among the seven groups (× 20). Notes: (a) NF-200-positive areas in the normal group; (b) NF-200-positive areas in the sham group; (c) NF-200-positive areas in the SCI group; (d) NF-200-positive areas in the NC group; (e) NF-200-positive areas in the PTC1-RNAi group; (f) NF-200-positive areas in PTC2-RNAi group; (g) NF-200-positive areas in the PTC1/PTC2-RNAi group; (h) comparison of the percentages of NF-200-positive areas among the seven groups detected by IHC; Gli-1, glioma-associated oncogene homolog 1; IHC, immunohistochemistry; NC, negative control; NF-200, neurofilaments-200; PTC1, Patched 1; PTC2, Patched 2; SCI, spinal cord injury; Shh, sonic hedgehog; *P<0.05 compared with the normal group; #P<0.05 compared with the SCI group; &P<0.05 compared with the PTC1/PTC2-RNAi group.
