Abstract

Mitochondrial dysfunction induces chondrocyte senescence, thereby precipitating articular cartilage (AC) degeneration in the pathogenesis of osteoarthritis (OA). Although the transfer of mitochondria from mesenchymal stem cells (MSCs) to host cells and their potential protective role have been demonstrated, whether MSCs can alleviate chondrocyte mitochondrial dysfunction or reverse OA progression remains unclear.

Research summary

Mitochondria-rich extracellular vesicles from mesenchymal stem cells can inhibit senescence in stressed chondrocytes and delay osteoarthritis progression. This research addresses mitochondrial dysfunction, a key factor in aging and age-related diseases, suggesting a potential mechanism to mitigate the effects of aging on cartilage health.
