Trophoblast apoptosis in human term placentas from pregnancies complicated with idiopathic intrauterine growth retardation

Abstract

The proliferative and apoptotic events in the trophoblast of placentas with idiopathic IUGR did not differ from physiologic ones. Study results suggest the IUGR syndrome to have no uniform etiology or even underlying pathophysiology that would determine the possible fetal risk and subsequent long-term consequences for fetal health and life. This imposes the need of a more precise definition and unambiguous distinction between the idiopathic and other forms of IUGR.
