Related to Endothelial tissue: epithelial tissue, Mesothelial tissue


The epithelial layer of cells lining the heart and vessels of the circulatory system.



a tissue found in animals and man consisting of specialized cells that line the inner surfaces of blood and lymph vessels, as well as the cavities of the heart. The endothelium is formed from the mesenchyme. It consists of a single layer of closely packed flat cells, which are usually separated from underlying tissues by a basal membrane. The endothelium of lymph vessels has no basal membrane. The cytoplasm of endothelial cells of certain capillaries may have pores that account for the permeability of the capillary wall, as, for example, in the renal glomeruli.

The endothelium of the enlarged capillaries of the blood-forming organs and the endothelium present in the liver, adrenal cortex, and certain other organs has a great capacity for phagocytosis. The endothelial cells of these organs belong to the reticuloendothelial system.

In laboratory experiments by Soll's group, mobile syncytia disrupted membranes made from collagen, a major structural protein in lymph nodes, and punched holes in endothelial tissue, which lines blood vessels.
Such complications include inflammation, creation of thrombus (blood clots) and, importantly, re-narrowing of arteries due to endothelial tissue re-growth inside blood vessels in the area of newly implanted stents.
