Oxidative stress in BMSCs exposed to H2O2 was alleviated by EGB or EGB CS. (A) MDA level changes in BMSCs treated with EGB or EGB CS; (B) SOD activities changes in BMSCs treated with either EGB or EGB CS; (C) CAT activities changes in BMSCs treated with either EGB or EGB CS. (D) GSH-Px activities changes in BMSCs treated with EGB or EGB CS. All data are presented as mean value ±SD and n=3 in each group. a) p<0.05, significantly different from control; b) p<0.05, significantly different from EGB; c) p<0.05, significantly different from EGB CS; d) p<0.05, significantly different from H2O2; e) p<0.05, significantly different from EGB + H2O2. one-way ANOVA.
