Shanghai Life Science epicardial progenitor cells

Epicardial fat surrounds the heart and coronary vessels is a visceral fat to cushion the heart protective effect also increases the risk of coronary heart disease, and coronary atherosclerosis, heart disease, there is a high correlation while the sources of these fats are still unknown.

Located in the heart cells of the outermost layer is a group of epicardial progenitor cells having pluripotency, research to date found to differentiate into fibroblasts, vascular smooth muscle cells or myocardial cells, but its ability to be converted into Mouse Free Tri-iodothyronine Indes ELISA Kit http://www.cusabio.com/ELISA_Kit-79135/ rarely have been reported. Research to explore the origins of epicardial fat may provide new research directions and ideas for the diagnosis and treatment of coronary heart disease.

In this study, doctoral student under the guidance of Zhou Bin Liu Qiaozhen and other researchers, the use of transgenic mice Wt1-CreERT2; Rosa-RFP, specific markers to track the fate of epicardial cell development. The results showed that embryonic cells labeled epicardial coronary vessels in addition to differentiate into smooth muscle cells than fat cells can also be formed between the atrioventricular heart. However, in the adult epicardial Shique again labeled this phenomenon was not observed, indicating that the ability of the outer membrane into the fat body into the center of the steady state is suppressed. Previous studies have shown that adult cardiac injury, the epicardial cells can re-stimulate the embryonic development of some of the features, differentiate into other cell types. Therefore, further study of the work under the change of heart damage epicardial cells into fat cells, the ability, the results of the accident found that the formation of fatty tissue injury site, while some of the fat cells is derived from the epicardium. The study also found that the cells derived from epicardial and are pluripotent, and under different culture conditions may be induced into adipocytes, chondrocytes and osteoblasts.
