VEGF and PlGF promote angiogenesis by interacting with the VEGF receptor family. Although both growth factors are produced by placenta, the serum level of PlGF rises much more significantly in pregnancy. In a study, Taylor et al demonstrated that the serum level of PlGF decreased in women who later developed preeclampsia. [28] The fall in serum level was notable as early as the second trimester in women who developed preeclampsia and intrauterine growth restriction.
