Human Infrapatellar Fat Pad Mesenchymal Stem Cell-derived Extracellular Vesicles Purified by Anion Exchange Chromatography Suppress Osteoarthritis Progression in a Mouse Model

CONCLUSION: Using an OA mouse model, we found that infrapatellar fat pad-derived MSC-extracellular vesicles could delay OA progression via alleviating pain and suppressing cartilage degeneration, osteophyte formation, and synovial inflammation. The autologous origin of extracellular vesicles and scalable purification method make our strategy potentially viable for clinical translation.CLINICAL RELEVANCE: Infrapatellar fat pad-derived MSC-extracellular vesicles isolated by anion exchange chromatography can suppress OA progression in a mouse model. Further studies with large-animal models, larger animal groups, and subsequent clinical trials are necessary to confirm the feasibility of this technique for clinical OA treatment.PMID:38662932 | DOI:10.1097/CORR.0000000000003067
