The effects of EVs-COS on the cell migration of chondrocytes induced by IL-1β. A The cell number in different groups determined by Transwell. B The area of cell migration in different groups measured by scratch test. *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
