Endothelial Cells
Endothelial cells are flat, thin cells that line the inside of blood vessels and lymph vessels, helping to form the endothelium. By controlling the passage of substances, including proteins and electrolytes, into and out of the bloodstream, endothelial cells help to regulate the body's circulation, support proper blood clotting, and defend against infections. They also play a role in inflammation and autoimmune responses. Endothelial cells can be found in all organs, and are important for healthy tissue and organ function. In some diseases, such as atherosclerosis, endothelial cells are damaged and can lead to an increased risk of cardiovascular problems. Endothelial cells are studied in the field of vascular biology to gain insight into cardiovascular disease, and to develop treatments for them.
