Abstract
Factor VIII-related antigen (FVIIIR:Ag) has been widely used as a marker for endothelial cells. Recent studies showed that U. europaeus agglutinin I lectin (UEAI) also binds specific endothelial cells. To determine the relative utility of the 2 endothelial cell markers, a group of vascular and nonvascular tumors was studied with both markers, using an immunoperoxidase method. UEAI is a more sensitive marker for endothelial cells than FVIIIR:Ag; it should be used as an additional diagnostic marker for endothelial cell-derived tumors.
