Exosomes derived from curcumin‐treated MSCs decreased IL‐1β‐induced apoptosis. A‐D, The result of TUNEL assay showed the apoptosis of primary chondrocytes treated under different conditions: control (A), IL‐1β(B), IL‐1β + EXO (C), IL‐1β + EXO‐CUR (D). E, The apoptosis of primary chondrocytes was increased when treated with IL‐1β, while the treatment with exosomes derived from curcumin‐treated MSCs dramatically reduced apoptosis (* P value < .05 vs control group, ** P < .05 vs IL‐1β group)
