ABSTRACT
Objective To investigate the therapy effects of bone marrow mesenchymal stem cells (MSCs) on renal recovery after ischemia-reperfusion injured. Methods Seventy-two Spargue-Dawley rats were randomly divided into 4 groups as normal control, sham operated control, I/R group(n=30) and the MSCs group. Rats were subjected to 45 min bilateral renal ischemial-reperfusion injury with microvascular clips, after 60 min of reperfusion they were injected in BrdU positive MSCs(1?106/mL)intravenously. The animals were sacrificed at 12 h, 3 d, 7 d, 14 d, and 42 d after reperfusion, and the bilateral kidney and blood samples were harvested. The blood urea nitrogen(BUN) and serum creatinine(Scr) were measured on automatic biochemistry analyzer. Renal morphologic changes were scored with Paller’s criterion on hematoxylin and eosin(H&E) stained sections. The apoptosis of tubular cells were examined by terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL). PCNA positive tubular cells were detected immunohistochemically as proliferation index. And confocal microscopy were used to identified the distribution of BrdU positive MSCs. Results After 12 h, 3 d of reperfusion, the Scr value of MSCs group were signifcantly lower than I/R group(P
