BMSCs-Derived Exosomal XPO7 Attenuates Osteoarthritis Progression by Targeting KDM2B to Ameliorate Chondrocyte Senescence.
Chondrocyte senescence is a central driver of osteoarthritis (OA) pathogenesis. While bone marrow mesenchymal stem cell-derived exosomes (BMSCs-Exos) exhibit therapeutic potential, their key functional components remain unclear. We therefore investigated whether Exportin-7 (XPO7), a protein enriched in BMSCs-Exos, alle...
