Endothelial cells form the intimal lining of the entire vascular system. The vascular endothelium is continuously and directly bathed by components of the bloodstream and represents the initial fixed anatomical surface with which these components come in contact. In the past decade, the methodologies for studying endothelial cell functions have markedly advanced, enabling direct and detailed study of the vascular endothelium. From such studies, it is now apparent that the vascular endothelium represents an extraordinarily complex network of cells demonstrating a multitude of distinct anatomic, metabolic, and immunologic properties critical to such processes as angiogenesis, atherosclerosis, thrombosis, neoplasia, and a variety of metabolic disorders including homocystinuria and diabetes mellitus. This report will focus on the interactions of insulin and the insulin-like growth factors (IGFs) with vascular endothelium, based on studies with cultured endothelial cells, isolated microvessels, and perfused organ systems. Data will be presented relevant to the following concepts: (1) endothelial cells, in culture and in vivo, have specific receptors for insulin, IGF-I, and IGF-II; (2) insulin, IGF-I, and IGF-II have both distinct and overlapping functions in cultured endothelial cells; (3) cultured endothelial cells process receptor-bound insulin, IGF-I, and IGF-II, by distinct processes; (4) in vivo, capillary endothelial receptors are integrally involved in the transport of intact insulin to subendothelial sites of insulin action; and (5) vascular endothelium has specialized cellular features that are likely to contribute to the unique interactions of endothelial cells with insulin and the IGFs.
