| Research Abstract |
Background.
Acute renal ischemic injury(AKI) represents a major clinical problem with renal arterial clamp at parial nephrectony. The use of therapy using adipose tissue-derived stem cells(ASCs) has been suggested as a potential modality to attenutate the ischemic renal damage. Methods. We investigated the possible renoprotection of pretreatment of ASCs before and after in a rat ischemia. reperfusion(I. R) model of AKI. Twenty-four hours postischemia, blood flow in peritubular capillaries(PTC) was measured using intravital videomicroscopy.
Results.
We demonstrated that ADRC therapy significantly reduced serum creatinine and BUN. Histological analysis further validated a significantly attenuated tubular damage. Intravital videomicroscopy and measurement of red blood cell velocity in peritubular capillaries showed ASCs-injected kidneys displayed significant hemodynamic improvement.
Conclusions.
The subscapular administration of ASCs to the kidney attenuates I/R renal injury though antiinflammation, antiapotoyic effect and peritubular capillary microcirculation. The present study suggests that ASCs would be a useful tool in preventing ishemic kidney damage in the clinical setting.
