In this study, we investigated EV efficacy from young BMSCs (2-month-old) in mitigating OA, contrasting them with EVs from aged BMSCs (27-month-old).

The therapeutic impact of EVs on chondrocytes under inflammatory responses was also evaluated. Despite having similar morphologies, EVs from young BMSCs markedly decreased senescence and improved chondroprotection by activating the PTEN pathway while simultaneously suppressing the upregulation of the PI3K/AKT pathways, proving to be more effective than those from older BMSCs in vitro. Furthermore, intraperitoneal injections of EVs from young donors significantly mitigated OA progression by preserving cartilage and reducing synovitis in a surgical OA model using DMM in mice.

First, we found that age-associated decline in endometrial functions including fibrosis and diminished receptivity, already exists in reproductive age. Subsequently, based on RNA-seq analysis, we identified several changes in molecular processes affected by age, including fibrosis, imbalanced inflammatory status including Th1 bias in secretory phase, cellular senescence and abnormal signalling transduction in key pathways, with all processes been further validated by molecular experiments. Finally, we uncovered for the first time that PI3K-AKT-FOXO1 signalling pathway is overactivated in ageing endometrium and is closely correlated with fibrosis and impaired receptivity characteristics of ageing endometrium. Blocking or activation of PI3K by LY294002 or 740Y-P could attenuate the effect of ageing or accelerate dysfunction of endometrial organoids.
