Adventitial cells are a type of connective tissue cells that are found in the outermost layer of blood vessels. These cells have a crucial role in maintaining the structure and function of blood vessels. In this article, we will explore the definition and meaning of adventitial cells, their origin, and their associations.
Definitions
Adventitial cells are defined as a type of fibroblast-like cells that are found in the adventitia layer of blood vessels. The adventitia layer is the outermost layer of blood vessels, which is composed of connective tissue cells, collagen fibers, and elastic fibers. Adventitial cells are responsible for regulating the growth and repair of blood vessels, and they play a crucial role in maintaining the structural integrity of blood vessels.
Origin
Adventitial cells are derived from mesenchymal stem cells, which are multipotent cells that can differentiate into various types of cells, including bone, cartilage, and connective tissue cells. During vascular development, mesenchymal stem cells differentiate into adventitial cells, which migrate to the outermost layer of blood vessels and contribute to the formation and maintenance of the adventitia layer.
Meaning in different dictionaries
The term “adventitial cell” is not commonly found in general dictionaries. However, in medical dictionaries, it is defined as a type of connective tissue cell that is found in the adventitia layer of blood vessels.
Associations
Adventitial cells have been associated with various physiological and pathological processes, including vascular remodeling, angiogenesis, atherosclerosis, and hypertension. These cells have been shown to play a crucial role in regulating the growth and repair of blood vessels, and their dysfunction has been implicated in the development of various vascular diseases.
Synonyms
Adventitial cells are also known as perivascular cells, fibroblasts, and mesenchymal cells.
Antonyms
There are no antonyms for adventitial cells.
The Same Root Words Adventitial Cell
The root word of adventitial cell is “adventitia,” which refers to the outermost layer of blood vessels. The term “adventitia” is derived from the Latin word “adventus,” which means “arrival” or “coming.”
