✦ Synopsis
In this review, we discuss recent advances in the study of the pathogenesis of congenital diaphragmatic hernia (CDH). Much of the research has involved the use of an animal model of CDH in which diaphragmatic defects are produced in fetal rats by administering the herbicide nitrofen to dams during mid-gestation. The animal model is described and the relevance to the human condition is discussed. The data derived from the animal studies are critically assessed in the context of commonly cited hypotheses proposed for the pathogenesis of CDH. Finally, experimental strategies are proposed for systematically examining the normal and pathological formation of the pleuroperitoneal fold. We conclude that a malformation of the primordial diaphragm, the pleuroperitoneal fold, underlies the muscle defects associated with CDH.
