Endothelial cells release substances that control vascular relaxation and contraction as well as enzymes that control blood clotting, immune function and platelet (a colorless substance in the blood) adhesion.hat Tests Are Used to Determine Endothelial Function. Acetylcholine endothelial function and adenosine coronary flow reserve tests enhance a physician's ability to diagnose and treat patients with endothelial dysfunction.
Introduction to Endothelial Cells. Endothelial cells (Fig.1) line the inside of every blood vessel in the body. They form a one-cell-thick layer called the endothelium, which is also found on the inner walls of the heart chambers and lymphatic vessels (which carry excess blood plasma around the body).The endothelium is very extensive.ain Function of Endothelial Cells.
