3 Fig. 2 Light micrographs of intimal hyperplasia in arterialized vein grafts. A, Section of 4-hour vein graft illustrates neutrophil adhesion to luminal surface with loss of endothelial cells. (Hematoxylin and eosin staining; original magnification × 400.) B, Section of 1 week vein graft illustrates transmural inflammatory infiltrate. (Hematoxylin and eosin staining; original magnification × 250.) C, Section of 2-week vein graft illustrating well-defined, hypercellular neointima. (Hematoxylin and eosin staining; original magnification × 400.) L represents lumen; I represents intima; N represents neointima; M represents media; A represents adventitia; arrow indicates internal elastic lamina.

6 Fig. 3 Light micrographs of arterialized vein graft sections stained with antimonocyte/macrophage antibodies. A, Immunostaining of 1-week vein graft demonstrates transmural infiltration of monocytes and macrophages (stained with ED-1 monoclonal antibody). B, Immunostaining of 2-week vein graft illustrates extravasated macrophages present in developing neointima and adventitia. Positive immunostaining appears black (arrows); note nuclei of other cells not stained with ED-1. (Original magnification × 400.) L represents graft lumen; N represents neointima; M represents media; A represents adventitia.

7 Fig. 4 RT-PCR analysis of amplified TGF-ß1 (top) and PDGF-A (middle) messenger RNA. Shown are value inversion scans of ethidium bromide-stained agarose gels. G3PDH was used as internal control (bottom). EV represents epigastric vein.
