The miRNA-146 in exosomes secreted by mBMSC could promote M2 macrophage polarization. RAW 264.7 cells were cultured with exosomes secreted by mBMSCs which incubated with WKYMVm peptide (1 μmol/L) or WKYMVm peptide (1 μmol/L) supplemented with miRNA-146 inhibitor for 24 h. a and b The quantification of M2 macrophage markers (CD206 and Arg-1) was measured by western blotting. Data represent means ± SD
