Comparative transcriptomic analysis of human epicardial progenitor cells and hiPSC-derived cardiac progenitor cells under hypoxic and normoxic culture conditions
Ontology highlight
ABSTRACT: The adult mammalian heart has been traditionally regarded as a post-mitotic organ with no regenerative capacity. However, this dogma has been refuted by some recent landmark studies. Both cardiac progenitor cells (CPCs) and epicardial progenitor cells (EPDCs) are activated after myocardium infarction and they may influence each other through paracrine mechanisms or direct interactions. Currently, efforts are being made to discover and develop therapeutic molecules to increase the number of CPCs and EPDCs in an infarcted heart. To better understand the characteristics and therapeutic potential of CPCs and EPDCs, as well as the regulatory mechanisms, we performed transcriptomic analysis of human iPSC-derived CPCs and human primary EPDCs and discovered unique gene expression profiles for each cell type. To make sure that the biological and pharmacological findings in cell assays under ambient oxygen conditions are relevant to the in vivo situation, it is important to understand the effect of hypoxia on the behavior, gene expression, and paracrine profiles of the cells.
Comparative transcriptomic analysis of human epicardial progenitor cells and hiPSC-derived cardiac progenitor cells was conducted. We performed global transcriptional analysis of two sources of cardiac progenitors, i.e., patient epicardium-derived cells (EPDCs) and cardiac progenitor cells (CPCs) derived from human induced pluripotent stem cells. In addition, we also compared the gene expression profiles of these cells when they were cultured under normoxic- and hypoxic conditions.
