After an acute myocardial infarction (AMI), cardiomyocytes (CMs) are eliminated and replaced by fibrous tissue displaying poor contractile capacity. The use of human induced pluripotent stem cells (hiPSCs) is a promising strategy to restore cardiac function, as these cells are able to differentiate into various cell types, such as CMs (hiPSC-CMs). However, the complete characterization of cells generated during differentiation as well as the choice of the optimal cell population to use for cardiac repair need to be further assessed. The objectives of this work are: 1) to test the hypothesis that mechanical stimulus could play a role during differentiation process or influence maturation status of hiPSC-CMs; 2) to determine if mechanical properties and calcium transient are critical parameters in the determination of the best hiPSC-CMs phenotype to use for therapeutic strategies or disease modeling. hiPSCs will be reprogrammed from cells isolated from urine of healthy individuals and patients from Instituto do Coração. These cells will be mechanically stimulated during their guided differentiation in CMs and phenotypically characterized by molecular/cell parameters and the proposed functional parameters (mechanical properties and calcium transient). This work can help increase the understanding and efficiency of the differentiation process of hiPSCs into the cardiac lineage, and contribute in the identification of the best functional parameters to test iPSC-CMs for both therapeutic purposes (after AMI, for example) and disease modeling for cardiac genetic disorders (hypertrophic cardiomyopathy, for instance).
