Nano-magnetic sorted CD29 +/CD44 +/CD105 + Bone MSCs alleviate cyclosporine nephrotoxicity and renal fibrosis
摘要
CD29/CD44/CD105-modified immunomagnetic liposomes (CD29/CD44/CD105-IMLs) were developed to isolate bone marrow mesenchymal stem cells (BMSCs) with distinct phenotypes. A key BMSC phenotype capable of alleviating chronic cyclosporine-induced nephropathy was identified through in vivo experiments in mice, demonstrating its potential as an effective adjunctive therapy for mitigating renal fibrosis-induced injury. Four weeks post-transplantation, mice receiving CD29+, CD44+, and CD105+ BMSC groups exhibited improved overall health compared to the control group. Western blot analysis of autophagy-related proteins LC3-II and P62 revealed significantly lower expression levels in the CD44+ BMSC group compared to the CD29+ and CD105+ BMSC groups. In vivo imaging further demonstrated enhanced chemotactic ability of CD44+ BMSCs in mice with chronic cyclosporine-induced nephropathy at various time points. These findings suggest that transplantation of CD29+/CD44+/CD105+ BMSCs can delay the progression of renal fibrosis in mice with cyclosporine-induced chronic kidney disease. Notably, CD44+ BMSCs exhibited superior efficacy in alleviating renal fibrosis compared to CD29+ and CD105+ BMSC groups.
