(Submitter supplied) Single cell RNAseq of a model of epicardium derived from human pluripotent stem cell (hPSC-epi) reveals that distinct epicardial sub-populations are defined by high levels of expression for the transcription factors BNC1 and TCF21. Cells positive for the transcription factor WT1 are included in the BNC1 population, which confirms the heterogeneity observed in the mouse with TCF21 and WT1. Analysis of genes differentially expressed between the two populations suggests differences in their biological activities. more...

(Submitter supplied) The embryonic epicardium provides a source of multipotent progenitors for cardiac lineages, including pericytes, fibroblasts and smooth muscle cells. However, it remains unclear if the epicardium comprises of heterogeneous progenitors or if epicardial cells are multipotent. Using scRNA-seq, we analysed the expression profile of epicardial and epicardial-derived cells at E15.5 and found no evidence of discrete epicardial sub-compartments. more...

(Submitter supplied) The aim of the approach was to use RNAseq analysis to identify genes expressed in Xenopus epicardium that were affected by embryonic depletion of the epicardial transcription factor Tcf21 compared to control-MO injected siblings. Both upregulated and downregulated genes were validated by RT-PCR and whole embryo in situ hybridization to validate gene expression and assess spatio-temporal distribution of genes of interest within the heart and epicardium. more...

(Submitter supplied) Recent genome wide association studies have identified a number of genes that contribute to the risk for coronary heart disease. One such gene, TCF21, encodes a basic-helix-loop-helix transcription factor believed to serve a critical role in the development of epicardial progenitor cells that give rise to coronary artery smooth muscle cells (SMC) and cardiac fibroblasts. Using reporter gene and immunolocalization studies with mouse and human tissues we have found that vascular TCF21 expression in the adult is restricted primarily to adventitial cells associated with coronary arteries and also medial SMC in the proximal aorta of mouse. more...

(Submitter supplied) Purpose: Studying the epicardium-myocardium crosstalk in the zebrafish larval heart. To do so, we aimed to identify, with RNA-seq, the genes dysregulated following the loss of the epicardial marker gene tcf21 in sorted epicardial cells and cardiomyocytes. Results: We first analyzed the transcriptome of epicardial and myocardial WT cells and identified cell-type specific/enriched genes. Then, we identified several differential expressed genes in tcf21 mutants, including several ligand-receptor couples known to mediate the epicardium-myocardium crosstalk.

(Submitter supplied) The epicardium is essential during cardiac development, homeostasis and repair and yet fundamental insights into its underlying cell biology, notably epicardium formation, lineage heterogeneity and functional cross-talk with other cell types in the heart, is currently lacking. In this study, we investigated epicardial heterogeneity and the functional diversity of discrete epicardial subpopulations in the developing zebrafish heart. more...

(Submitter supplied) To delineate the role of the epicardium, the initial site of presentation of the ACM phenotype, the Dsp gene, encoding desmosome protein desmoplakin (DSP) was conditionally deleted in the mouse epicardial cells under the transcriptional regulation of Wilms tumor 1 (Wt1) locus. Single cell RNA sequencing (scRNA-Seq) of ~ 40,000 tagged epicardial-derived cells (EDCs), isolated using the dual reporter R26mT/mG mice, showed an increased number of EDCs expressing unique molecular identifiers of fibroblasts as well as a unique subset of epicardial-derived fibroblasts expressing pro-fibrotic genes in the Wt1-Cre: R26mT/mG: Dsp mice. more...

Protocols have been established to generate epicardial cells and their progeny from human pluripotent stem cells in vitro. However, no current model is amenable to studying the many facets of human epicardial biology, notably epicardium formation, lineage heterogeneity, and functional crosstalk with other cardiac cell types during organ development and disease. more...

(Submitter supplied) The goal of the present study is to determine the miRNA cargo present in epicardial extracellular vesicles. For that, epicardial cells and human primary epicardial cells were cultured. Conditioned media was isolated from mouse epicardial cells and human primary epicardial cells derived from right atrial appendages in two different states: “cobble” (inactive) cells and “spindle” (active) . RNA from EVs was isolated and sequenced to determine the miRNA content profile.

(Submitter supplied) 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). more...

(Submitter supplied) The transcriptional profiles of cardiac cells derived from murine embryos and from mouse embryonic stem cells (mESCs) have primarily been studied within a cell population. However, the characterization of gene expression in these cells at a single cell level may demonstrate unique variations that are not able to be appreciated as a pool. In this study, we aimed to establish a single cell quantitative PCR platform and perform side-by-side comparison between cardiac progenitors cells (CPCs) and cardiomyocytes (CMs) derived from mESC and mouse embryos. more...

(Submitter supplied) By contrast with mammals, adult zebrafish have a high capacity to regenerate damaged or lost myocardium through proliferation of spared cardiomyocytes. The epicardial sheet covering the heart is activated by injury and aids muscle regeneration through paracrine effects and as a multipotent cell source, and has received recent attention as a target in cardiac repair strategies. While it is recognized that epicardium is required for muscle regeneration and itself has high regenerative potential, the extent of cellular heterogeneity within epicardial tissue is largely unexplored. more...
