Abstract
Myocardial infarction causes irreversible loss of cardiomyocytes, culminating in negative cardiac remodeling and heart failure (HF). Considering the limited intrinsic repair ability of myocardial, and a high morbidity and mortality due to HF even with the optimized therapeutic arsenal, searches for more effective alternatives to attenuate the cardiac remodeling post-infarction reigns in the literature. In this regard, mesenchymal stem cells (MSCs) transplantation is a promising approach to restore cardiac function. The MSCs expand easily ex vivo and show differentiation for endothelial cells and cardiomyocytes in vitro. Moreover, the paracrine benefits of MSCs arising from the secretion of growth factors and immunomodulatory (e.g., cytokines). Although experimental and clinical studies have illustrated benefits of MSCs in infarcted hearts, there are no singular findings. Main reasons for these findings are reduced cell adhesion in the organ and cell death linked to inhospitable microenvironment in the infarcted myocardium. Therefore, new approaches are needed to enhance cellular home and to improve the resistance as well as efficiency of CTMs. Using a preclinical myocardial infarction model in rats, we will investigate: 1) the hypothesis that light emitting diode (LED) stimulus can improve the viability and proliferation and, potentiate the secretion of cytokines and growth factors of mesenchymal stem cells of adipose tissue (CTMA). Additionally, we will test different irradiation parameters, targeting to determine the LED dose with more evident biological effects; 2) whether in vitro pre-irradiation with LED improves the therapeutic CTMA action in the infarcted heart.
