Growth retardation and low birth weight represent an important factor associated with the high risk of mortality and morbidity, particularly in twin pregnancy, since twins are frequently characterised by fetal growth retardation and sometimes by a discordant growth between the twins. The present work sets out to elucidate the role of growth discordance between twins in the behaviour of human umbilical vein endothelial cells; biochemical, ultrastructural and immunohistochemical data obtained from a discordant twin pregnancy are discussed. Endothelial cells were obtained from umbilical cord of 5 singleton pregnancies and from 5 dichorionic twin pregnancies, among which was one discordant twin pregnancy. Membrane fluidity was assayed using a fluorescent probe and each sample was immunohistochemically processed employing specific monoclonal antibodies. An increased fluidity was observed in endothelial cells from the smaller twin as compared with the larger one. As concerns electron microscopy, the features of endothelial cells from the smaller twin were similar to those of twins with similar growth, while endothelial cells from the larger one were more similar to those from singleton pregnancies. Our findings confirm the presence of the feto-fetal transfusion as a pathogenetic mechanism involved in twin growth discordancy.
