Endothelial Cells (Large Vessels)

The endothelium is the thin layer of endothelial cells that line the interior surface of blood and lymphatic vessels - from the aorta to the smallest capillaries. In large vessels (arteries and veins), it is enclosed by two other layers namely the tunica media and the tunica externa (see Figure).

PromoCell endothelial cells (large vessels) are available from the umbilical vein and artery, the aorta, the coronary artery, the pulmonary artery, and the saphenous vein. All endothelial cells are tested for positive expression of vWF and CD31, and the absence of smooth muscle alpha-actin.

Available endothelial cell types (large vessels):
