Endothelium vs. Mesothelium: Know the Difference
By Shumaila Saeed || Published on January 1, 2024
Endothelium is the tissue forming the inner lining of blood vessels and lymphatic vessels, whereas mesothelium lines body cavities like the chest and abdomen.
Key Differences
Endothelium plays a crucial role in controlling vascular functions, such as blood clotting and pressure regulation, by producing vasoactive substances. Mesothelium, on the other hand, provides a lubricating surface for organs within the body cavities, facilitating smooth movement and reducing friction.

Endothelium lines the entire circulatory system, including the heart and blood vessels, and is a thin layer of simple squamous cells. Mesothelium covers the pleura, peritoneum, and pericardium, and is composed of a layer of flattened epithelial cells.

Endothelium dysfunction is a key factor in cardiovascular diseases, affecting blood flow and vessel integrity. Mesothelium is sensitive to asbestos exposure, leading to mesothelioma, a type of cancer associated with this tissue.

Endothelium originates from the mesoderm layer during embryonic development, specifically from angioblasts. Mesothelium also arises from the mesoderm but differentiates from a distinct set of precursor cells, indicating diverse developmental pathways.

Endothelium and Mesothelium Definitions
Endothelium
Endothelium is the innermost layer of cells lining blood vessels.
The endothelium regulates blood flow in the arteries.

Mesothelium
Mesothelium plays a role in fluid transport within cavities.
The mesothelium helps to regulate fluid in the pleural cavity.

Endothelium
Endothelium acts as a barrier between the blood and the rest of the vessel wall.
Damage to the endothelium can lead to vascular diseases.

Mesothelium
Mesothelium is a membrane that lines body cavities and covers internal organs.
The mesothelium of the abdomen is called the peritoneum.

Mesothelium
Mesothelium provides a slippery, non-adhesive, and protective surface.
The mesothelium allows the lungs to expand and contract smoothly.

Mesothelium
Mesothelium consists of a layer of flat mesothelial cells.
The mesothelium's cells provide a barrier against infection and injury.

Endothelium
Endothelium secretes substances controlling vessel dilation and contraction.
The endothelium releases nitric oxide to dilate blood vessels.

Mesothelium
Mesothelium is sensitive to certain carcinogens like asbestos.
Asbestos exposure can cause mesothelioma, a cancer of the mesothelium.
