Fifteen studies explore diverse questions concerning the development of vascular endothelial cells. Among the topics: endothelial fenestrae and fenestral diaphragms, adhesian molecules in endothelial cells and their role in vascular morphogenesis, vascular development (including retinal vasculature), the blood-brain barrier, pulmonary microvasculature, the kidney vascular system, the liver vascular system, and the limb bud vascular system. Risau, deceased, was director of the Max-Planck-Institute in Bad Neuheim; Rubanyi is a researcher at Berlex Biosciences in Richmond, California. Annotation c.
