Oxidative Stress Induces Chondrocyte Apoptosis through Caspase-Dependent and Caspase-Independent Mitochondrial Pathways and the Antioxidant Mechanism of Angelica Sinensis Polysaccharide

Figure 4

Alter of mitochondrial function in chondrocytes induced by various treatments. Cultured and treated chondrocytes were harvested, and the levels of cytochrome C (a), SOD-2 (b), and ATP (c) in different groups were measured by assay kit. Results are presented as of three independent experiments. Untreated chondrocytes were used as normal control. , versus normal control. ^#, ^## versus H₂O₂ group.
