Gene expression profiling in porcine chronic myocardial ischemia treated with intramyocardial injections of secretome

ABSTRACT: Closed-chest reperfused MI was induced in pigs by 90-min occlusion, followed by reperfusion of the mid LAD (day 0) and by cardiac MRI with late enhancement (LE) at day 3. At day 30 the animals received either porcine APOSEC (n=8) or placebo medium (n=8) in a randomized manner, injected into the border zone of MI using 3D NOGA percutaneous intramyocardial guidance. At day 60, control cardiac MRI with LE and measurements of myocardial viability via diagnostic NOGA were performed. Gene expression profiling of the infarct core, border zone and normal myocardium was performed using microarray analysis, confirmed by quantitative real-time PCR. Percutaneous endomyocardial injections of APOSEC led to a significant (p<0.05) decrease in infarct size and in improvement of cardiac index and myocard
