Angioblast
Angioblast
Angioblast (/æn.dʒi.oʊ.blæst/; from the Greek angio-, meaning "vessel", and blast-, meaning "germ") is a type of cell that is involved in the formation of blood vessels. It is a precursor cell that differentiates to form endothelial cells, which are the cells that line the interior surface of blood vessels.
Function
Angioblasts play a crucial role in angiogenesis, the process of new blood vessel formation from pre-existing vessels. They migrate to areas where new vessels are needed, proliferate, and differentiate into endothelial cells to form the new vessel.
Development
During embryogenesis, angioblasts are derived from mesoderm, one of the three primary germ layers in the very early embryo. They form clusters known as blood islands, which eventually develop into the vascular system.
