A Oxidative stress-related genes was verified to be modulated by CDs. B CDs exerted its mediatory roles in oxidative stress-induced cartilage injury through targeting Nrf2 signaling pathway. C Mitochondrial dysfunction induced by IL-1β was rescued by CDs incubation. Scar bar: 40 μm **p < 0.01; ***p < 0.001Back to article page
