===Vasculogenesis===
===Vasculogenesis===
Vasculogenesis occurs during the third week of gestation in domestic mammals, initially in the yolk sac and afterwards in the allantois. The blood vessels form from blood islands called haemangioblasts which develop from mesodermal cells in the presence of fibroblast growth factor. Exposure to angiopoietin and vascular endothelial growth factor (VEGF) stimulate differentiation of haemangioblasts to endothelial cells.
