Fig. 3From: Protective effects of aucubin on osteoarthritic chondrocyte model induced by hydrogen peroxide and mechanical stimulusFluorescence imaging of ROS production. Chondrocytes pretreated with 100 μM of aucubin for 24 h were then stimulated with 1 mM H2O2 for 30 min. The green and red colors are the fluorescence of general ROS (hydrogen peroxide, peroxynitrite, hydroxyl radicals, nitric oxide, peroxy radical) and superoxide, respectively. Chondrocytes without aucubin nor H2O2 treatment were set as the control group. Scale bar = 100 μm. (5 repeated measurements for each group)Back to article page
