Viability of human saphenous vein grafts under different pressure conditions. A) Veins were perfused with either venous (10 mmHg) or arterial pressure profiles (100 mmHg). Viability of cells was tested using the MTT conversion assay as described in Material and Methods. n = 6 for both conditions. B) Representative MTT stainings of HSVGs at different time points.
