Abstract

The main goal of this project is to characterize the optimal hiPSC-derived cell population for cardiac regeneration after MI, using a preclinical model of Ml in pigs. First, human iPSCs will be generated from either human fibroblasts or urine samples using a non-integrative reprogramming strategy based on episomal transfection. hiPSCs will be characterized to ensure they show the typical features of pluripotent stem cells. Then, we will differentiate them toward the cardiac lineage using an efficient modified protocol based on small molecules enabling Wnt pathway control. The second aim of this project is a thoroughly characterization of cell populations at different stages of differentiation, from immature mesoderm cells to mature cardiomyocytes (targeting committed, although not fully differentiated cardiomyocytes). We will then perform a pilot study using a rat model of myocardial infarction to identify the optimal cell (AU)
