2. Fig. 1
SEM photomicrographs of nonimplanted HUV graft. A, Luminal surface is smooth with occasional shallow folds (× 20). B, No endothelial cells remain on flow surface while underlying elastic lamina is visible at places where basement membrane is damaged (× 200).

3. Fig. 2
Photomicrographs showing wall of unused HUV graft in cross-section. A, Luminal lining is devoid of endothelial cells as seen following paraffin embedding and hematoxylineosin staining (× 400). B, Elastica lamina has corrugated appearance following Epon embedding and PPDA staining (× 400).

4. Fig. 3
Photomicrograph of graft from experiment 3 implanted for 4 months. A, Lumen at distal anastomosis was virtually occluded by poorly adhering thrombotic accumulation. B, This was confirmed by SEM (× 20). C, Smooth luminal surface contained fibrin deposits (× 100), which did not appear to adhere well as they were rolled up and displaced downstream (D, × 500).

5. Fig. 4
Photomicrographs of graft from experiment 7 showing mismatch in diameter after 7½ months. A, Just above distal anastomosis wall was very thin and translucent. Smooth and glistening luminal surface was almost devoid of fibrin deposits and few endothelial-like cells were seen along anastomosis (B, × 50).

6. Fig. 5
Section through wall of graft from experiment 9 after implantation. Lumen of graft is on left. Note presence of endothelial-like cells on luminal surface (arrow). Wall of graft has lost most of its cellularity and there is hyalinization of muscular and collagenous components. Outer fibrous sheath is result of chronic inflammatory response with mononuclear cells, Dacron mesh, fibrous tissue, and small nutrient vessels (× 100).
