Abstract Normal human pregnancy depends on physiological transformation of spiral arteries. Pre-eclampsia and fetal growth restriction are associated with impaired trophoblast invasion and spiral artery transformation. Recent data obtained from studies on placenta suggest that temporal changes in expression of TGF-beta3 play a key role in trophoblast invasion and that over-expression of TGF-beta3 in pre-eclampsia is responsible for inadequate trophoblast invasion. There are, however, no studies of specific TGF-betas in the placental bed throughout pregnancy although this is where the invasive trophoblast and spiral arteries are located. In this study we have used immunohistochemistry, Western blot analysis, ELISA and RT-PCR to examine the expression of TGF-beta1, TGF-beta2 and TGF-beta3 in placental bed biopsies and placentas from 7--19 weeks' gestation. The results show that TGF-beta1, 2 and 3 are expressed in the placenta throughout this time but the striking temporal changes in TGF-beta3 expression previously reported were not observed. Extravillous trophoblast within the placental bed expressed TGF-beta2 but not TGF-beta1 or TGF-beta3 while extracellular TGF-beta1 and cytoplasmic TGF-beta2 were detected in decidua. These data suggest that TGF-beta1 and TGF-beta2 but not TGF-beta3 may play a role in trophoblast invasion. Copyright 2002 Harcourt Publishers Ltd.
