Abstract
Hybrid vascular prostheses are coated with vascular endothelial cells (EC) in an attempt to reduce thrombogenicity through the metabolic activities of living cells. The present studies were planned to develop a standardized method of isolating bovine aortic EC with high yield for studies of endothelial coating of vascular prostheses. The best results were achieved using a combination of incubation with collagenase and mechanically scraping the mobilised cells from the donor vessel. Isolated adult male bovine endothelial cells were identified by the typical "cobble stone" morphology in culture and characterized by factor VIII related antigen immunofluorescence microscopy. The cells were seeded successfully on PTFE vascular prostheses.
