Abstract
Great progress has been made in the last several years in our ability to culture human endothelial cells. In addition, techniques to immediately procure and utilize these cells have also been developed. The purpose of this paper is to present an overview of the current and potential uses of these cells in both vascular and nonvascular conditions. It is likely that endothelial cells will be used in a variety of applications in the near future. Immediately procured and cultured cells will be used to resurface vascular prosthetic grafts. They may also be used on the surface of vessels following procedures such as balloon angioplasty or atherectomy. In addition, they may be placed upon the surface of implantable devices such as expandable stents. Through the mechanism of genetic engineering, these cells may be modified to produce proteins, which may modify thrombogenicity and perhaps decrease the rate of recurrent stenosis by influencing cellular hyperplasia. Genetically modified endothelial cells also have great potential in nonvascular disease. Their contact with circulating blood makes them an ideal cell for production of proteins to correct systemic conditions such as the insulin deficiency found in diabetes mellitus. The application of endothelial cell biology in both vascular and nonvascular science represents one of the most exciting fields of research active today.
