Pericytes are a type of cell that surrounds blood vessels, particularly capillaries and post-capillary venules. They are a key component of the blood-brain barrier and play a crucial role in maintaining the integrity of the vessel wall and regulating blood flow. Pericytes also have been implicated in the pathogenesis of various diseases, including cancer, atherosclerosis, and neurological disorders.
Pericytes are a type of cell found in the walls of blood vessels, particularly in capillaries and venules. They are perivascular cells that help to support the surrounding endothelial cells and smooth muscle cells that form the blood vessel wall. Pericytes play a crucial role in maintaining blood vessel integrity and facilitating the exchange of nutrients and waste products between the blood vessels and surrounding tissues. They can also help to regulate blood flow by contracting or relaxing their walls to adjust blood vessel diameter. In addition, pericytes have been found to have a role in the development and progression of various diseases, including angiogenesis, inflammation, and cancer.
