Abstract
Factor-VIII-related antigen was localized in adult human blood vessels using immunofluorescence and EM. In addition to its presence in endothelial cells, the antigen was localized within subendothelium and the layers of elastic lamina closest to the lumen. The 1st morphological evidence that factor-VIII-related antigen is associated with collagen fibrils within the vessel wall is provided. This subendothelial factor-VIII-related antigen may play a role in the adhesion of platelets to subendothelial components following endothelial injury.
