The effects of curcumin on mouse chondrocyte viability and cell morphology. (A) The chemical formula of curcumin. (B) MTS assays were used to analyze the viability of chondrocytes cultured in 10, 20, 50, and 100 µM curcumin for 24 hours. (C) Absorbance at 490 nm by chondrocytes treated with IL-1β (10 ng/mL) alone or IL-1β (10 ng/mL) and curcumin (10, 20, and 50 µM) simultaneously for 24 hours. (D,E,F) Cell morphology of the murine knee chondrocyte treated with or without curcumin (50 µM) in the presence of IL-1β (10 ng/mL). Magnification 100×. #, P<0.05 vs. control group; *, P<0.05 vs. IL-1β group. Cur, curcumin; IL-1β, interleukin-1β; OD, optical density.
