Endoteelisolussa

Endoteelisolussa, commonly referred to as endothelial cells, form the inner lining of all blood and lymphatic vessels. These cells are crucial for maintaining vascular health and function. They create a barrier between the bloodstream and the surrounding tissues, regulating the passage of substances in and out of the vessels. Endothelial cells play a vital role in hemostasis, preventing excessive bleeding by initiating blood clot formation when a vessel is injured. They also participate in inflammation by allowing immune cells to adhere to the vessel wall and migrate into tissues. Furthermore, endothelial cells produce various signaling molecules, including nitric oxide, which helps to relax blood vessels and regulate blood pressure. Dysfunction of endothelial cells is implicated in a wide range of diseases, including atherosclerosis, hypertension, and diabetes. They are a dynamic and responsive cell type, constantly adapting to physiological stimuli and contributing significantly to overall cardiovascular and systemic homeostasis.
