Grades of histopathologic injuries in rats with no intervention (control); rats that underwent laparotomy without clamping of renal vessels and received PBS solution and equivalent 48-hr perfusion period (Sham); rats with 45 min of ischemia and 48 hr of reperfusion that received PBS (I/R 48 hr+ PBS); rats with 45 min of ischemia and 48 hr of reperfusion that had received 2×10⁶ adipose-derived mesenchymal stem cells (I/R 48 hr+stem cell)
