The effects of EVs-COS on the cell viability and apoptosis of chondrocytes induced by IL-1β. A After culturing for 24, 48, and 72 h, the cell viability of chondrocytes with different treatments were determined using Cell Counting Kit-8 (CCK-8). B The cell apoptosis of chondrocytes with different treatments were detected by flow cytometer. *P < 0.05, compared with the control group; #P < 0.05, compared with the IL-1β group; $P < 0.05, compared with the IL-1β + COS group; &P < 0.05, compared with the IL-1β+EVs group
