Background: VEGFR1/Flt-1

Vascular Endothelial Growth Factor Receptor 1 (VEGFR1) is a receptor tyrosine kinase that is expressed primarily on endothelial cells and plays a role in vasculogenesis and angiogenesis. A soluble variant of VEGFR1 was also reported to bind VEGF and PlGF with high affinity and function as a potent VEGF antagonist.
