ENGINNERING CARDIAC TISSUE USING HUMAN INDUCED PLURIPOTENT STEM CELL DERIVATIVES: PROTEOMIC CHARACTERIZATION OF CO-CULTURES OF CARDIOMYOCYTES AND ENDOTHELIAL CELLS

摘要

Prediction of cardiac toxicity effect is extremely relevant in the development of new drugs for different medical applications. In this way, it is important to develop more predictable human cell-based models which physiologically better mimic the human heart and allow the prediction of this toxic effect as well as establish the tools that enable the characterization of these complex cell models. To recreate engineered cardiac tissue, it is essential to reproduce the complexity of the heart by resorting to different cell types. Cardiomyocytes (CMs) are functional contractile units of the heart, and it is known that their communication with endothelial cells (ECs) is crucial for cardiac homeostasis. The aim of this study is to recreate a human pluripotent stem cells (hiPSC)-based cardiac tissue model and evaluate the impact of communication between both cell types on the phenotype of CMs.
