Mesenchymal stem cells (MSCs) turned macrophages into M2 types in vitro. A, Representative immunofluorescence staining images (original magnification: ×400). When co‐culture with MSCs or MSCs’ supernatant, CD163 expression (red) of macrophages was increased. (n=4). B, Fluorescence‐activated cell sorting analysis showed that MSCs and MSC supernatant both induced M2 macrophages polarization (CD163). (n=4). MSC indicates mesenchymal stem cells. (Data are presented as mean±SD, ***P<0.001 vs macrophages, ANOVA with Tukey post hoc test).
