We describe here a protocol for culturing epicardial cells from adult zebrafish hearts, which have a unique regenerative capacity after injury. Briefly, zebrafish hearts first undergo ventricular amputation or sham operation. Next, the hearts are excised and explanted onto fibrin gels prepared in advance in a multiwell tissue culture plate. The procedure allows the epicardial cells to outgrow from the ventricle onto a fibrin matrix in vitro. This protocol differs from those used in other organisms by using a fibrin gel to mimic blood clots that normally form after injury and that are essential for proper cell migration. The culture procedure can be accomplished within 5 h; epicardial cells can be obtained within 24-48 h and can be maintained in culture for 5-6 d. This protocol can be used to investigate the mechanisms underlying epicardial cell migration, proliferation and epithelial-to-mesenchymal transition during heart regeneration, homeostatic cardiac growth or other physiological processes.

ITFG2 is an intracellular protein known to modulate the immune response of T-cells. Our previous investigation revealed that ITFG2 specifically targets ATP5b to regulate ATP energy metabolism and maintain mitochondrial function, thereby protecting the heart from ischemic injury. However, the role of ITFG2 in ischemic ventricular arrhythmias and its underlying mechanisms have not been previously reported.

Epicardium, the most outer mesothelium, exerts crucial functions in fetal heart development and adult heart regeneration. Here we use a three-step manipulation of WNT signalling entwined with BMP and RA signalling for generating a self-organized epicardial organoid that highly express with epicardium makers WT1 and TCF21 from human embryonic stem cells. After 8-days treatment of TGF-beta following by bFGF, cells enter into epithelium-mesenchymal transition and give rise to smooth muscle cells.

The Wilms' tumor suppressor WT1 is essential for the development of the heart, among other organs such as the kidneys and gonads. The Wt1 gene encodes a zinc finger transcription factor that regulates proliferation, cellular differentiation processes, and apoptosis. WT1 is also involved in cardiac homeostasis and repair.

FoxP3 T-regulatory (Treg) lymphocytes and cytokine production by cells from the stromal vascular fraction (SVF) of epicardial (EAT) and thymus (TAT) adipose tissue of 42 patients with chronic coronary heart disease (CHD) were studied. In the SVF of TAT in patients with Gensini Score (GS)≥74 (the most severe atherosclerosis), the production of IL-1β, TNF, IL-4, and IFNγ was higher, while FoxP3 translocation into the nucleus was lower than in patients with GS<74. The GS index directly correlated with the production of IL-4, IL-1β, and TNF by cells of the SVF of TAT, and inversely - with the production of TNF, IL-17, and IL-10 by cells of the SVF of EAT.

Cardiac fibroblasts are activated following myocardial infarction (MI) and cardiac fibrosis is a major driver of the growing burden of heart failure. A non-invasive targeting method for activated cardiac fibroblasts would be advantageous because of their importance for imaging and therapy. Targeting was achieved by linking a 7-amino acid peptide (EP9) to a perfluorocarbon-containing nanoemulsion (PFC-NE) for visualization by F-combined with H-MRI.
