Transcriptomic analysis of different human cardiac cell types produced in vitro from human pluripotent stem cells or derived from patients. (human)
The epicardium, an epithelium covering the heart, is essential for cardiac development. During embryogenesis, the epicardium provides instructive signals for the growth and maturation of cardiomyocytes and for coronary angiogenesis. We generated an in vitro model of human embryonic epicardium derived from human pluripotent stem cells (hPSC-epi). These cells were able to differentiate into cardiac fibroblasts (cf) and smooth muscle cells (smc) in vitro (hPSC-epi-cf and hPSC-epi-smc respectively). Furthermore, we showed that they improved maturation of hPSC-derived cardiomyocytes (hPSC-cardio) in vitro while neural crest cells derived from hPSC (hPSC-NC) could not.
