Hemangioblast
Hemangioblast
Hemangioblast (pronunciation: he-man-gee-o-blast) is a type of cell that is believed to be a precursor to both endothelial cells and hematopoietic cells.
Etymology
The term "hemangioblast" is derived from the Greek words "haima" meaning blood, "angeion" meaning vessel, and "blastos" meaning germ.
Definition
A hemangioblast is a multipotent cell that can differentiate into both endothelial cells, which form the lining of blood vessels, and hematopoietic cells, which give rise to all other blood cells. This dual potentiality is a key feature of hemangioblasts and is critical to the formation of the circulatory system during embryonic development.
Related Terms
- Endothelial cells: These are cells that line the interior surface of blood vessels and lymphatic vessels, forming an interface between circulating blood or lymph in the lumen and the rest of the vessel wall.
- Hematopoietic cells: These are the blood cells that give rise to all other blood cells through the process of hematopoiesis.
- Hematopoiesis: This is the formation of blood cellular components.
- Circulatory system: This is the organ system that permits blood to circulate and transport nutrients, oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases.
