Abstract In the bone immune microenvironment, cells can regulate osteoblasts through a complex communication network. Macrophages play central role in mediating osteogenesis, exosomes derived from them have osteogenic regulation and be used as carriers tissue engineering. However, there are problems with exosomal therapy alone, such poor targeting, content of loaded molecules cannot reach therapeutic concentration. this study, macrophage-derived modified miR-365-2-5p were developed to...
