AIMS: To determine the long-term effect of transplantation of adipose-derived stromal cells (ADSCs) in a preclinical model of ischemia/reperfusion (I/R).METHODS AND RESULTS: I/R was induced in 28 Goettingen minipigs by 120 minutes coronary artery occlusion followed by reperfusion. Nine days later, surviving animals were allocated to receive trans-endocardial injection of a mean of 213.6±41.78 million green fluorescent protein (GFP)-expressing ADSCs (n=7) or culture medium as control (n=9). Heart function, cell engraftment and histological analysis were performed 3 months after transplantation. Transplantation of ADSCs induced a statistically significant long-lasting (3 months) improvement in cardiac function and geometry in comparison with control animals.Functional improvement was associated with an increase in angiogenesis and vasculogenesis and a positive effect on heart remodeling with a decrease in fibrosis and cardiac hypertrophy in animals treated with ADSCs. Despite the lack of cell engraftment after 3 months, ADSC transplantation induced changes in the ratio between MMP/TIMP.CONCLUSION: Our results indicate that transplantation of ADSCs, despite the lack of longterm significant cell engraftment, increases vessel density and prevents adverse remodeling in a clinically relevant model of myocardial infarction, strongly suggesting a paracrine mediated effect. ADSCs thus constitute an attractive candidate for the treatment of myocardial infarction.
