Comparison of the relative expression of PTC1, PTC2, Shh, Gli-1, Nestin and Smo proteins among the seven groups on the 7th, 14th and 28th days. Notes: (a) relative expression of PTC1, PTC2, Shh, Gli-1, Nestin and Smo proteins on the 7th day; (b) relative expression of PTC1, PTC2, Shh, Gli-1, Nestin and Smo proteins on the 14th day; (c) relative expression of PTC1, PTC2, Shh, Gli-1, Nestin and Smo proteins on the 21st day; (d) relative expression of Shh protein; (e) relative expression of Gli-1 protein; (f) relative expression of Smo protein. Relative expression of Nestin protein; (h) relative expression of PTC1 protein; (i) relative expression of PTC2 protein; Gli-1, glioma-associated oncogene homolog 1; NC, negative control; 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.
