Schematic diagram of the experiments assessing macrophage-mediated bone formation of DBM-ECM in vivo and in vitro. (A) Material preparation and characterization. (B) In vivo experiments assessing the role of macrophages in ECM-induced bone formation (a) and the effect of the MIF signaling pathway on macrophage-mediated bone formation (b). (C) In vitro experiments investigating the role of conditioned media of macrophages on osteogenesis of hBMSCs and the mechanism of macrophage-mediated osteogenesis of MSCs induced by ECM.
