Endothelial cell-selective materials for tissue engineering in the vascular graft via a new receptor

We have found a novel adhesion receptor on the human endothelial cell for the peptide sequence Arg-Glu-Asp-Val (REDV), which is present in the III-CS domain of human plasma fibronectin, with a dissociation constant of 2.2 x 10(-6) M and 5.8 x 10(6) sites/cell. When a synthetic peptide containing this sequence was immobilized on otherwise cell nonadhesive substrates, endothelial cells attached and spread but fibroblasts, vascular smooth muscle cells, and platelets did not. Endothelial monolayers on REDV were nonthrombogenic: endothelial cells attached and spread upon other receptor-binding domains of fibronectin and laminin, but with lesser degrees of specificity or with a loss of nonthrombogenicity. This approach may provide a basis for a tissue engineered vascular graft where endothelial cell attachment is desired, but not the attachment of other blood vessel wall cells and blood platelets.
