Abstract
Bone marrow (BM)-derived mesenchymal stromal cells (MSC) participate in myocardial repair following myocardial infarction (MI). However, their reparative capability is limited, partly because of poor homing abilities. MI is associated with an inflammatory reaction. Interleukin-8 (IL-8) appears to have a fundamental role in regulating neutrophil localization in ischemic tissues through binding CXCR1/CXCR2 receptors, which show major expression on neutrophils. We hypothesize that the application of IL-8 will enhance the recruitment of overexpressing CXCR1/CXCR2 MSC to sites of degenerated tissue of myocardium, decreasing the ischemic region and improving cardiac function.
