Immunohistochemistry and expression changes of PDGF-BB and ERK1/2 after PDGF-BB regulation. A–D Results of GFAP, NeuN, SYP, and TUNEL staining in the damaged cerebral cortex among the Sham, TBI, and HBO groups (100 × , Scale bars = 100um). E The western blotting results and the relative protein expression levels of PDGF-BB and phosphorylated ERK1/2 (p-ERK1/2) at 7 d and 14 d after TBI among the Sham, Injury, and HBO groups. F Comparison of the relative mRNA expression levels of PDGF-BB and ERK1/2 at 7 days and 14 days after TBI among the Sham, Injury, and HBO groups. ^*P < 0.05, vs. PDGF-BBi group; ^#P < 0.05, vs. PDGF-BB group
