Effects of CMs generated by unpolarized Mφs (CM0) and polarized Mφs (CM1 and CM2) on bone marrow mesenchymal stem cell (BMMSC) proliferation; normal complete medium (Norm) was used as a control. (A) Proliferative capacity of BMMSCs in different cultures evaluated by Cell Counting Kit‐8 (CCK‐8) assays during a 7‐day incubation period. (B) Proliferative capacity of BMMSCs in different cultures determined by EdU incorporation assays; representative images showing EdU‐positive cells (red fluorescence; scale bar: 100 μm). (C) Representative images of colony‐forming units (CFUs) (top) and a single CFU (bottom) formed by BMMSCs in different cultures on day 14 (scale bar: 250 μm). (D) Quantitative analysis of the number of CFUs formed by BMMSCs in different cultures; data are shown as the mean ± SD; **P < 0.01 and ***P < 0.001 represent significant differences between the indicated columns.
