Effects of Ononin on cell viability. (A) Rat chondrocytes were intervened on Ononin (1 nM to 100 μM) only or (B) with IL-1β (10 ng/ml) for 24 h and cell viability was detected by CCK-8 kit. (C) The cell density (% of Control) of different groups was calculated by Image-J software. (D) Chondrocytes were treated with Ononin with or without IL-1β (10 ng/ml) and photographed by phase-contrast microscopy (20×) (scale bar: 50 μm). **P < 0.01 compared with control group; ##P < 0.01 compared with IL-1β group
