Low vacuum SEM and immunofluorescent image of platelet adhesion on vascular grafts with different topography. (a) Nothing but small amount of cellular debris adhered on the smooth topography. (c) Protein-like substances adhered on the aligned topography along the direction of blood flow and aligned nanofibers. (b) ~ (d) Few platelets adhered on both topography. Broken black arrows indicate the direction of the blood flow, and white arrows indicate the adhered platelets.
