Failure of the directed differentiation of the transplanted stem cells into cardiomyocytes is still a major challenge of cardiac regeneration therapy. Our recent study has demonstrated that the expression of histone deacetylase 1 (HDAC1) is decreased in bone mesenchymal stem cells (BMSCs) during their differentiation into cardiomyocytes. However, the potential roles of HDAC1 in cardiac cell dif...
Understanding molecules involved in differentiation of human pluripotent stem cells (hPSCs) into cardiomyocytes and endothelial cells is important in advancing hPSCs for cell therapy and drug testing. Here, we report that LGR5, a leucine-rich repeat-containing G-protein-coupled receptor, plays a critical role in hPSC differentiation into cardiomyocytes and endothelial cells. LGR5 expression was...
Background and Objective: Human embryonic stem cells (hESCs) can differentiate in vitro into spontaneously contracting cardiomyocytes and produce a model to investigate the early developmental stages of this system. After removing of cells from their feeder layer, hESCs create embryoid bodies (EB). Plating of EB results in developing areas of beating cells. In the present study, cardiomyocyte g...
Cytosolic Ca2+ ([Ca2+]i) is an important signal that regulates cardiomyocyte differentiation during cardiogenesis. TRPV1 is a Ca2+-permeable channel that is expressed in cardiomyocytes. In the present study, we utilized mouse embryonic stem cell-derived cardiomyocytes (mESC-CMs) as a model to investigate the functional role of TRPV1 in cardiomyocyte differentiation. Induction of embryonic stem ...
The anterior heart field (AHF) encompasses a niche in which mesoderm-derived cardiac progenitors maintain their multipotent and undifferentiated nature in response to signals from surrounding tissues. Here, we investigate the signaling mechanism that promotes the shift from proliferating cardiac progenitors to differentiating cardiomyocytes in chick embryos. Genomic and systems biology approach...
Recent advances in pluripotent stem cell biology and directed differentiation have identified a population of human cardiovascular progenitors that give rise to cardiomyocytes, smooth muscle, and endothelial cells. Because the heart develops from progenitors in 3D under constant mechanical load, we sought to test the effects of a 3D microenvironment and mechanical stress on differentiation and ...
In the developing heart, cardiomyocytes undergo terminal differentiation during a critical window around birth. Hypoxia is a major stress to preterm infants, yet its effect on the development and maturation of the heart remains unknown. We tested the hypothesis in a rat model that newborn anoxia accelerates cardiomyocyte terminal differentiation and results in reduced cardiomyocyte endowment in...
Mitochondrial morphology is crucial for tissue homeostasis, but its role in cell differentiation is unclear. We found that mitochondrial fusion was required for proper cardiomyocyte development. Ablation of mitochondrial fusion proteins Mitofusin 1 and 2 in the embryonic mouse heart, or gene-trapping of Mitofusin 2 or Optic atrophy 1 in mouse embryonic stem cells (ESCs), arrested mouse heart de...
