The differences between the two cells, besides where they are located, can be summarized as follows:
- They have different cytoplasm concentrations (little to none for endothelium, high levels for mesothelium)
- Endothelium directly contacts lymph and blood, draining interstitial fluid and acting against infection.
- Mesothelium protects vital organs in internal body cavities.
What is the difference between endothelium and mesothelial cells?
Mesothelium and endothelium cells appear in different locations. The endothelium lines tube-shaped vessels like blood vessels. Mesothelium, meanwhile, covers the organs’ outer surfaces. This is the main difference between the two cells, but there are many more. This is interesting since the two are often confused.
What is the endothelium?
The endothelium is a thin layer of supporting connective tissue that lines the internal surfaces of blood vessels, lymph vessels and the heart. It is a type of specialized epithelium that composes simple squamous epithelial cells. Furthermore, it consists of a single flattened cell layer.
What is mesothelium?
What is Mesothelium. Mesothelium is the epithelium that lines the peritoneum, pericardium, and pleura. Mesothelial cells originate from the mesoderm. The peritoneum is the serous membrane which lines the abdominal cavity. The visceral peritoneum and the parietal peritoneum are the two categories of the peritoneum.
What is the difference between mesothelium and peritoneum?

The mesothelium is the layer of tissues (epithelium) that surrounds the organs of the chest (pleura and pericardium), abdominal cavity (peritoneum and mesentery), and pelvis (including the tunica vaginalis that surrounds the testes).
What is the difference between an endothelium and an epithelium?
Endothelium generally lines fully internal pathways (such as the vascular system), while epithelium generally lines pathways that are open to the external environment (such as the respiratory and digestive systems). Nerve cells are specialized for signaling, and red blood cells are specialized for oxygen transport.
What is a mesothelium?
The mesothelium is an epithelial structure derived from the embryonic mesoderm. It plays an important role in the development of a number of different organs, including the heart, lungs, and intestines.
Why is it called mesothelium?
Origin. Mesothelium derives from the embryonic mesoderm cell layer, that lines the coelom (body cavity) in the embryo. It develops into the layer of cells that covers and protects most of the internal organs of the body.
Which tissue is sometimes called endothelial or mesothelial?
(The inner lining of the cornea is also called "corneal endothelium," but that is a different specialized tissue.) The major body cavities (peritoneal, pleural, pericardial) are lined by a mesodermally derived simple squamous epithelium that is called mesothelium.
What is the endothelium?
The endothelium is a thin membrane that lines the inside of the heart and blood vessels. Endothelial cells release substances that control vascular relaxation and contraction as well as enzymes that control blood clotting, immune function and platelet (a colorless substance in the blood) adhesion.
What is endothelium made of?
The endothelium is a thin layer of single flat (squamous) cells that line the interior surface of blood vessels and lymphatic vessels. Endothelium is of mesodermal origin. Both blood and lymphatic capillaries are composed of a single layer of endothelial cells called a monolayer.

Is the mesothelium a membrane?
The mesothelium is a membrane that covers and protects most of your internal organs. It is made up of 2 layers. The inner layer wraps around different organs, including the lungs, heart and stomach. The outer layer forms a sac around the inner layer.
Is mesothelium connective tissue?
Peritoneal mesothelium produces peritoneal fluid. The mesothelial cells are supported by a basal membrane in continuity with a thin layer of richly vascularized loose connective tissue, with lymphatics and fatty tissue, which is called the subserosa.
Where is mesothelium in the body?
The mesothelium is a protective membrane that covers the lungs, abdomen, heart and testes.
What is the function of the mesothelium?
The main function of the mesothelium in the peritoneum, pericardium, and the pleura is to provide a slippery but, non-sticky surface between the organs, protecting the organs in the chest and the abdomen and allowing the functioning of the organs. Other than that, the mesothelium allows the movement of fluids and substances between the internal organs and the outer environment. It also helps in blood clotting and tissue healing. The mesothelium also plays an immunological role against infections and the formation of tumors. Mesothelioma, adhesions, fibrosis, and pleural effusions are the common complications of the mesothelium.
Where is the mesothelium located?
Location. Mesothelium: Mesothelium is found in all the serous membranes of the body such as pericardium, peritoneum, and pleura and internal reproductive organs. Endothelium: Endothelium lines the inner surface of the blood vessels, lymphatic vessels and the heart.
What is the epithelium of the heart?
Endothelium is the epithelium that lines the cavities of various organs such as blood vessels, lymphatic vessels, and the heart. It can originate from either endoderm or ectoderm. Arteries and veins are the major blood vessels that carry blood throughout the body.
What are the two types of membranes that line the body cavities of animals?
Mesothelium and endothelium are two types of membranes that line the body cavities of animals. Mesothelium is originated from mesoderm whereas endothelium is derived from ectoderm and endoderm in the early embryo. In adults, both mesothelium and endothelium are made up of simple squamous epithelium. The main difference between mesothelium and endothelium is that, in adults, mes othelium occurs in all serous membranes of the body such as pericardium, peritoneum, and pleura and internal reproductive organs whereas the endothelium lines the inner surface of the blood vessels, lymphatic vessels, and the heart. Therefore, mesothelium is the middle covering of the body whereas endothelium is the inner covering.
What is the role of mesothelium in the body?
Other than that, the mesothelium allows the movement of fluids and substances between the internal organs and the outer environment. It also helps in blood clotting and tissue healing. The mesothelium also plays an immunological role against infections and the formation of tumors.

The endothelium is involved in the formation of the blood vessels and blood clotting. It controls the blood pressure by involving in the vasoconstriction and vasodilation.
Why aren't epithelial cells considered true?
The reason why they are not classed as true epithelium is because the pathology of both endothelium and mesothelium is incredibly different. As a result, when someone is diagnosed with cancer, these cancers are labeled as mesothelium and endothelium sarcomas. A true epithelial cancer is known as a carcinoma. There are many differences between ...

What are the components of the amniotic membrane?
Decellularized amniotic membrane. Extracellular matrix proteins and natural polymers such as collagen, fibronectin, laminins, gelatin, alginate, chitosan, and silk fibroin. One of the key elements that also has to be studied how biological scaffolds go through the mesothelialization process.
Where do fibroblasts come from?
It is also known that the fibroblasts and vascular smooth muscle cells’ mesenchymal precursors come from the transformation from epithelial to mesenchymal, which happens in the epicardial mesothelium. However, it is not yet understood where the coronary endothelium comes from.
Can mesothelium differentiate from endothelium?
Scientists have long been concerned about whether or not it is possible to differentiate between mesothelium and endothelium cells. Fortunately, the Von Willebrand Factor, which showed that there are a number of cell markers that are specific for endothelial cells, was discovered.
Abstract
