What is the Meaning of Endothelial Cells?

Endothelial Cells constitute the single-cell layer lining the interior surface of all blood and lymphatic vessels, serving as a dynamic interface between circulating blood components and underlying tissues. Their integrity is crucial for vascular health and paracrine signaling.

What is the Origin of Endothelial Cells?

The name reflects their anatomical location, derived from Greek meaning 'lining within,' accurately describing their role as the internal boundary of the circulatory system.

What is the Mechanism of Endothelial Cells?

These cells actively participate in regulating vascular tone through the production of vasodilators like nitric oxide (NO) and vasoconstrictors such as endothelin-1. Furthermore, they regulate the permeability of the vessel wall, influencing the local availability of circulating hormones and nutrients to adjacent cells.
