Fig. 2. MM2P promoted switch from M1 to M2 phenotype to facilitate cartilage repair.
BMDMs were treated with IL-4 or LPS to induce M2 or M1 polarization. a Quantification of F4/80+CD206+ ratio in IL-4-treated BMDMs, and F4/80+CD86+ ratio in LPS-treated BMDMs. b RT-qPCR of MM2P levels in BMDMs of each group. c The IL-4-treated BMDMs were transfected with sh-NC or sh-MM2P#1/2, whereas the LPS-treated BMDMs were transfected with pcDNA3.1 or pcDNA3.1/MM2P. RT-qPCR of MM2P levels in BMDMs of each group. d Quantification of F4/80+CD206+ ratio in IL-4-treated BMDMs, and F4/80+CD86+ ratio in LPS-treated BMDMs. e RT-qPCR of MM2P levels in BMDMs of each group. f Western blots of p-STAT1, STAT1, p-STAT6, STAT6, p-STAT3, STAT3, and quantification of p-STAT1/STAT1, p-STAT6/STAT6, and p-STAT3/STAT3 in BMDMs treated with IL-4 and LPS. **P < 0.01. The error bar expressed as mean ± SD of three independent experiments in triplicates.
