microvascular endothelial cells

Microvascular endothelial cells are the thin, specialized cells lining the smallest blood vessels in the body, called capillaries. These cells form a selective barrier that controls the exchange of oxygen, nutrients, and waste products between blood and tissues. They also play key roles in immune response, blood clotting, and maintaining blood vessel health. Because of their location and functions, microvascular endothelial cells are essential for tissue health, healing, and ensuring proper circulation at the microscopic level throughout the body.
