Chondrocytes were cultured with IL-4/IL-13-induced M2 macrophages with indicated transfections. a RT-qPCR and western blot experiments for the SOX9 mRNA and protein levels in chondrocytes of each group. b Levels of Acan, Col2a1, and Col1a1 in chondrocytes of each group. c, d The production of sGAG and Collagen II in chondrocytes of each group. **P < 0.01. The error bar expressed as mean ± SD of three independent experiments in triplicates.
