چکیده

The epicardium is a critical tissue that directs several aspects of heart development, particularly via the secretion of soluble factors. This review summarizes recent approaches that implicate the epicardium as the source of mitogenic factors promoting cardiomyocyte proliferation, as the source of instructive signals that direct compact zone organization (morphogenesis), and as the tissue that directs formation of the coronary vasculature.

Cardiac-specific overexpression of human stem cell factor promotes epicardial activation and arteriogenesis after myocardial infarction.

BACKGROUND The adult epicardium is a potential source of cardiac progenitors after myocardial infarction (MI). We tested the hypothesis that cardiomyocyte-specific overexpression of membrane-associated human stem cell factor (hSCF) enhances epicardial activation, epicardium-derived cells (EPDCs) production, and myocardial arteriogenesis post MI. METHODS AND RESULTS Wild-type and the inducible...

Differential Notch signaling in the epicardium is required for cardiac inflow development and coronary vessel morphogenesis.

RATIONALE The proepicardium is a transient structure comprising epicardial progenitor cells located at the posterior limit of the embryonic cardiac inflow. A network of signals regulates proepicardial cell fate and defines myocardial and nonmyocardial domains at the venous pole of the heart. During cardiac development, epicardial-derived cells also contribute to coronary vessel morphogenesis. ...

Mesenchymal Stem Cells Derived from Rat Epicardial Versus Epididymal Adipose Tissue

Objective(s) Some investigation has indicated that adipose-derived stem cells possess different surface epitopes and differentiation potential according to the localization of fat pad from which the cells were derived. In the present study proliferation capacity and aging of such cells were explored. Materials and Methods Adherent cells were isolated from the collagenase digests of adipose tiss...

WT1 regulates the expression of inhibitory chemokines during heart development.

The embryonic epicardium is an important source of cardiovascular precursor cells and paracrine factors that are required for adequate heart formation. Signaling pathways regulated by WT1 that promote heart development have started to be described; however, there is little information on signaling pathways regulated by WT1 that could act in a negative manner. Transcriptome analysis of Wt1KO epi...

Growth Kinetics and in Vitro Aging of Mesenchymal Stem Cells Isolated From Rat Adipose Versus Bone Marrow Tissues

Objective- To investigate and compare growth potential as well as aging of mesenchymal stem cells (MSCs) derived from rat bone marrow tissue and adipose tissue (AT) occurred at epicardial and epididymal regions. Design- Experimental study.   Animals- 10 Wistar Rats.   Procedures- Rat MSCs occurred at bone marrow and epicardial and epididymal AT were isolated and culture expanded through sev...
