ABSTRACT
BACKGROUND AND OBJECTIVES:
Cisplatin is a nephrotoxic chemotherapeutic agent. So, preventive measures worth to be evaluated. Human amniotic fluid stem cells (hAFSCs) in prevention or amelioration of cisplatin-induced acute kidney injury (AKI) in Sprague-Dawley rates have been tested.METHODS:
80 Sprague-Dawley rats (250~300 g) were used and divided into 4 major groups, 20 rats each. Group I Saline-injected group. Group II Cisplatin-injected group (5 mg/kg I.P). Group III Cisplatin-injected and hAFSCs-treated group (5×106 hAFSCs I.V. one day after cisplatin administration). Group IV Cisplatin-injected and culture media-treated group. Each major group was further divided into 4 equal subgroups according to the timing of sacrifice; 4, 7, 11 and 30 days post-cisplatin injection. Renal function tests were done. Kidney tissue homogenate oxidative stress parameters malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione (GSH) were determined. Histopathological scoring systems for active injury, regenerative and chronic changes were analyzed separately.RESULTS:
hAFSCs characterization and differentiation was proved. Cisplatin injection resulted in a significant increase in serum creatinine and MDA and decrease in SOD, GSH and creatinine clearance. These changes were attenuated early by day 4 with the use of hAFSCs. Cisplatin injection induced tubular necrosis, atrophy, inflammatory cells infiltration and fibrosis. The use of hAFSCs was associated with significantly lowered injury score at day 4, 7, 11 and 30 with marked regenerative changes starting from day 4.CONCLUSION:
hAFSCs have both a protective and regenerative activities largely through an antioxidant activity. This activity cut short the acuteness of cisplatin nephrotoxicity.
