چکیده
Objective(s): Reducing the immune response to inflammation is vital for successful transplantation, yet chronic graft rejection remains a major issue despite immunosuppressive drugs. This study explored the effect of bone marrow mesenchymal stem cell-derived exosomes on the survival of skin allografts in mice.Materials and Methods: C۵۷BL/۶ and BALB/c mice underwent skin allograft surgery, followed by intraperitoneal injection of exosomes, which were compared with groups receiving dexamethasone and no treatment group.Results: On day ۳, mild signs of graft rejection appeared in both control groups, while none were seen in the exosome-treated group. By day ۱۴, the grafts were completely rejected in the control groups but showed mild rejection in the treatment group. Histopathology revealed severe rejection signs in the control groups, including epithelial necrosis and inflammation, while the treatment group showed signs of angiogenesis and graft acceptance. Additionally, inflammatory cytokine levels (TNF-α, IL-۱β, and IL-۶) were lower in the treatment group than in the positive control group, particularly on days ۳ and ۱۴.Conclusion: The findings suggest that exosomes can prevent graft rejection and may offer a promising therapeutic approach for solid organ transplantation, though further research is needed to standardize exosome methods and evaluate cost-effectiveness.کلیدواژه ها
