Protective effect of GS on H2O2-induced cytotoxicity and intracellular oxidative status in osteoblasts. a Concentration-dependent effects of H2O2 exposure on the morphology of osteoblasts after 24 h (b) Concentration-dependent effects of H2O2 exposure on viability of osteoblasts (c) Representative photomicrographs show intracellular ROS generation stained with DCFH-DA dye, Scale bar = 100 μm (d) Quantitative measurement of ROS level of osteoblasts was expressed as the percentage of DCF-fluorescence relative to controls. Values were obtained from three independent experiments and expressed as mean ± SEM. *P < 0.05 compared with control
