From: Preserving the endothelium in saphenous vein graft with both conventional and no-touch preparation
The inside of the residual SVG was observed with scanning microscopy. An unbiased observer reported no significant differences between the conventional (CV) and no-touch (NT) preparations. Representative images are shown in (a). The arrow indicates microvillus, a characteristic of endothelium. Scale bar, 1 μm. A summary is shown in (b). The average number of microvilli is indicated (n = 2).
