Abstract: Provided is a use of dipsaci radix-derived extracellular vesicle-like nanoparticles (DREVNs) in preparation of a drug for preventing or treating orthopedic diseases. In this application, EVs are creatively extracted from dipsaci radix and purified, and the physiological efficacy of the EVs is studied. It has been found that the EVs can be fully internalized by bone marrow mesenchymal stem cells (BMSCs), can promote the osteogenic differentiation of BMSCs by activating a BMP2/Smads signaling pathway, promote the calcified nodule formation in BMSCs, and promote the expression of osteogenic differentiation-associated genes ALP, OCN, RUNX2, and COL1, and have bone targetability in vivo. The EVs can be intragastrically administered to alleviate the osteoporosis (OP) in postmenopausal mice. Therefore, the EVs have the potential of being used to prepare drugs for preventing or treating orthopedic diseases, and provide a new strategy for the prevention or treatment of orthopedic diseases.
