Placental growth factor (PLGF) is a member of PDGF/VEGF family growth factors. PLGF, a member of VEGF family, is produced mainly by placenta and is normally found in urine and blood during pregnancy. Angiogenesis and vascular transformation are important processes in the normal development of the placenta. Abnormal angiogenesis and vascular transformation are considered one of the main reasons for preeclamptic pregnancies and intrauterine growth retardation. In pre-eclampsia, there is increased expression of soluble fms-like tyrosine kinase-1 (sFlt1) which binds to circulating PLGF. Consequently, concentrations of plasma PLGF are found to be decreased in pregnant women with pre-eclampsia.
