The effect of macrophage-derived exosomes on the expression of osteogenesis-related genes in BMSCs. The bar graphs show the effect of normal or inhibited macrophage exosome secretion on the levels of osteogenesis-related mRNAs in BMSCs in the cell co-culture model. Inhibition of macrophage exosomal secretion significantly down-regulated the expression of BMP-2, RUNX2, OPN, and OC in BMSCs in the cell co-culture model at 24 and 48 h; the macrophages were pre-stimulated using hypoxia or CSF. ##p < 0.01, #p < 0.05. Each experiment was repeated five times.
