The aim of this immunohistochemical investigation was to study the distribution of the novel cytoskeletal protein smoothelin and the intermediate filament proteins vimentin and desmin in normal human great saphenous vein and in human aortocoronary by-pass vein grafts. Smoothelin was present in most smooth muscle cells in the media of the native vein. In the neointima of the vein grafts that had been in situ for three months or more, smoothelin was, in general, present only in few smooth muscle cells. Desmin was distributed in the same pattern as smoothelin in the native great saphenous vein. When desmin and smoothelin were present in the neointima, smoothelin was detected in more cells than desmin. Vimentin was present in most cells in all wall layers of both the native saphenous vein and the vein grafts. Vascular smooth muscle cells containing vimentin but not desmin or smoothelin are the principal cells in the neointima of human aortocoronary vein grafts. In some grafts, however, all three cytoskeletal proteins were detected in the neointima. The distribution of smoothelin and desmin in aortocoronary vein grafts support the postulate that these proteins are expressed mainly in the contractile smooth muscle cell phenotype.
