We hypothesized that adipose-derived mesenchymal stem cells ADMSCs protect the kidney against oxidative stress and inflammatory stimuli in rat during renal IR injury. Methods Adult male Sprague-Dawley SD rats n 24 were equally randomized into group 1 sham control group 2 IR plus culture medium only and group 3 IR plus immediate intra-renal administration of X 106 autologous ADMSCs followed by intravenous ADMSCs at 6 h and 24 h after IR . The duration of ischemia was 1 h followed by 72 hours of reperfusion before the animals were sacrificed. Results Serum creatinine and blood urea nitrogen levels and the degree of histological abnormalities were markedly lower in group 3 than in group 2 all p . The mRNA expressions of inflammatory oxidative stress and apoptotic biomarkers were lower whereas the anti-inflammatory anti-oxidative and anti-apoptotic biomarkers were higher in group 3 than in group 2 all p . Immunofluorescent staining showed a higher number of CD31 von Willebrand Factor and heme oxygenase HO -1 cells in group 3 than in group 2 all p . Western blot showed notably higher NAD P H quinone oxidoreductase 1 and HO-1 activities two indicators of anti-oxidative capacity in group 3 than those in group 2 all p . Immunohistochemical staining showed higher glutathione .
