Extraembryonic Angioblasts (ExBI)

Extraembryonic angioblasts are located at the peripheral layer of the blood islands and serve as the progenitor cells of blood vessels, while the inner cells of the blood islands serve as blood progenitor cells. These angioblasts later multiply and differentiate into endothelial cells, forming the lining of the blood vessels.
