Abstract

To explore the effect of adenovirus-mediated human stromal cell-derived factor-1alpha (hSDF-1alpha) on ventricular remodeling in rats with myocardial infarction. A recombinant adenoviral plasmid containing hSDF-1alpha cDNA was constructed using homologous recombination in bacteria and the recombinant adenovirus particles expressing hSDF-1alpha (AdV-SDF-1) were prepared. In rat models of myocardial infarction induced by left anterior descending artery occlusion, 1x10(10) PFU AdV-SDF-1 or PFU AdV-LacZ were injected at multiple sites into the infarcted myocardium 1 h after the operation, using 200 l cell-free PBS as the control. Four weeks after the injection, the cardiac function of the rats was analyzed, and the heart tissues were taken after the measurement of hemodynamics. On serial frozen sections, histological observation and morphometric measurement were carried out using a microscopic image analysis system, and the expression of hSDF-1alpha was detected by immunocytochemistry. Four weeks after AdV-SDF-1 injection, the myocardium in the infracted area showed significantly higher expression rates of hSDF-1alpha. The injection resulted in a obvious reduction in the infarct size and collagen content and a marked increase in th...Continue Reading
