Introduction. Graphene-based nanomaterials have shown some degrees of stem cell protection against cell death. Due to their distinctive function, the kidneys are exposed to many toxic substances. On the other hand, minor and trivial effects of stem cells have been reported for the treatment of acute kidney injury (AKI). Here, we explain the use of Graphene oxide (GO) for improving the efficacy of mesenchymal stem cells (MSCs) in the treatment of Cisplatin-induced AKI. Methods. In this study, GO particles were synthesized in our lab. Cisplatin-induced AKI was modeled on rats. Thirty adults male Wistar Albino rats were divided into five groups: control group (did not receive any treatment), Cisplatin group (received 5 mg/ kg cisplatin intraperitoneally), sham group (received 500 µL saline intraperitoneally 5th days after Cisplatin injection), [Cisplatin + MSCs] group (received 5×106 /kg MSCs after Cisplatin injection), and [Cisplatin+ MSCs + GO] group (received 1.5 mg/kg GO + MSCs after Cisplatin injection. Biochemical analysis of serum creatinine (Cr) and blood urea nitrogen (BUN) levels, as well as histological study of the kidneys in diverse groups were compared. The oneway analysis of variance (ANOVA) and Dunnett’s test were used for comparisons between the study groups. Results. GO improved the effects of MSCs transplantation on serum Cr and BUN in AKI rat models. It also reduced cell death, hyaline casts, and cell debris in the animal models compared to the MSCs group. Conclusion. It could be concluded that GO can enhance the efficacy of MSCs transplantation in the treatment of damaged kidneys. [ABSTRACT FROM AUTHOR]
