Plant-derived exosome-like nanoparticle (PELN) is a nanoscale vesicle secreted by plant cells, which has important biological functions. On the one hand, PELN can exert anti-osteoporosis (OP) effects by affecting the functions of osteoclasts, osteoblasts, and bone marrow mesenchymal stem cells. On the other hand, PELN can also inhibit inflammatory reactions, protect chondrocytes, and has potential value in treating osteoarthritis (OA). This article summarizes the basic concepts, formation and components, separation and characterization methods of PELN, and focuses on the intervention effect and molecular mechanism of PELN on OP and OA.
