Capillary Endothelium

Molecular classification
Cell Type, Barrier, Endothelial cell
01

Overview

The capillary endothelium refers to the single layer of endothelial cells that lines the interior surface of capillaries, the smallest blood vessels. This barrier regulates exchanges between blood and tissues, including fluid, nutrients, gases, and waste products. It plays key roles in vascular tone, angiogenesis, hemostasis, and immune response. Alterations in capillary endothelial function contribute to diseases like atherosclerosis, diabetes-related vascular complications, and chronic inflammation, making it an important therapeutic target.
