Detection of mitochondrial function. (A) Intracellular ROS; (B) fluorescence intensity; (C) NO; (D) MMP; (E) fluorescence intensity; (F) cytochrome C. Control chondrocytes cultured in DMEM were used as control. Results are presented as means ± standard deviation of three independent experiments. ***P < 0.001 versus Con. ##P < 0.01, ###P < 0.001 versus OA.
