Fetal growth restriction is associated with increased apoptosis in the chorionic trophoblast cells of human fetal membranes

Abstract

The aim of the study was to determine the incidence and spatial distribution of apoptotic cell in fetal membranes obtained from human pregnancies complicated with fetal growth restriction (FGR) for which there was no established cause. Fetal membrane samples from normal (n = 10) and FGR-affected (n = 10) pregnancies were collected and stored following delivery. The incidence of apoptosis and the number of apoptotic cells in normal and FGR-affected fetal membranes were determined using immunohistochemistry and a monoclonal antibody for neo-epitope of cytokeratin-18, M30. The level of apoptotic proteins in FGR-fetal membranes compared to the normal tissue was determined using Western immunoblo..
