Cell death in the morphogenesis and teratogenesis of the heart

In spite of the continuing progress of research in the fields of cellular and molecular biology, which has oriented many embryologists towards molecular biology, no concrete explanation of morphogenesis has yet been found. The present state of knowledge of heart development is characterized by an enormous discrepancy between the qualitative descriptions of what happens on the organ level and the more or less quantitative information on subcellular and molecular events. It is generally not unders
