Background and objectives: Exosomes, which are small nanoscale vesicles capable of secretion, have garnered significant attention in recent years because of their therapeutic potential, particularly in the context of kidney diseases. Notably, human umbilical cord mesenchymal stem cell-derived exosomes (hucMSC-Exos) are emerging as promising targeted therapies for renal conditions. The aim of this study was to investigate the therapeutic effects of hucMSC-Exos on diabetic kidney disease (DKD) both in vivo and in vitro. Additionally, this study seeks to elucidate cellular and molecular differentials, as well as the expression of relevant signaling pathways, through single-cell RNA sequencing. This endeavor was designed to enhance our understanding of the connection between hucMSC-Exos and the pathogenesis of DKD. Methods and results: The study commenced with the extraction and characterization of hucMSC-Exos, including the determination of their concentrations. Animal experiments were conducted to evaluate the therapeutic potential of hucMSC-Exos in a DKD mouse model. Subsequently, single-cell sequencing was employed to investigate the molecular mechanisms underlying the efficacy of extracellular vesicles in ameliorating DKD. These findings were further substantiated by cell-based experiments. Importantly, the results indicate that hucMSC-Exos can impede the progression of DKD in mice, with macrophage activation playing a pivotal role in this process. Conclusions: The in vivo experiments conclusively established hucMSC-Exos as a pivotal component in preserving renal function and retarding the progression of DKD. Our utilization of single-cell sequencing technology, in conjunction with in vivo and in vitro experiments, provides compelling evidence that M2 macrophages are instrumental in enhancing the amelioration of diabetic nephropathy. |
