Application of membrane-coated nanoparticles in bone /cartilage regeneration. A Schematic illustration of neutrophil membrane-coated PLGA nanoparticles alleviated joint damage. Reprinted with permission [180]. B Schematic representation of infrared laser-responsive erythrocyte member NPs system. Reprinted with permission [182]. C The generation of erythrocyte member NPs, which also showed the ability of anti-osteolysis abilities. Reprinted with permission [183]. D Schematic diagram of hybrid member of neck squamous cell carcinoma WSU-HN6 cell and erythrocyte fabrication, which showed the ability to target bone. Reprinted with permission [184]. E The generation of apoptotic chondrocyte membrane-coated nanoparticles loaded quercetin, which capable of repolarizing macrophages from the M1 to M2, and the signals on apoptotic chondrocyte membrane made the components been phagocytized by synovial macrophages more easily. Reprinted with permission [185]. F The generation of RAW-PLGA nanodecoys, which could suppress osteoporosis by inhibiting osteoclastogenesis and promoting osteoblastogenesis.
