Immunohistochemistry results showed that the exosomes derived from curcumin‐treated MSCs recovered the normal expression of ROCK1 protein in OA mice. A, Immunohistochemistry analysis showed abnormally increased NF‐kB protein expression in OA mice, while the exosomes derived from curcumin‐treated MSCs recovered the normal expression of NF‐kB protein. B, Immunohistochemistry analysis showed abnormally increased ROCK1 protein expression in OA mice, while the exosomes derived from curcumin‐treated MSCs recovered the normal expression of ROCK1 protein
