Lymphatic endothelial cells

Lymphatic endothelial cells line the inside of lymphatic vessels, which are part of the body's immune and fluid balance systems. These specialized cells form a thin, flexible barrier that helps transport lymph—a fluid containing immune cells, waste, and nutrients—through the body. They play a crucial role in filtering harmful organisms, maintaining tissue fluid levels, and supporting immune responses. Essentially, lymphatic endothelial cells are the building blocks of the lymphatic network, ensuring efficient movement of immune cells and fluids, and helping the body stay protected and balanced.
