Figure 5: (A) APC activity by EOCs on the in vitro ePTFE samples for collagen I and fibronectin modified grafts. *indicates statistical significance using a paired t-test, p<0.05, n=3.(B) Cumulative platelet deposition on the EOC-seeded ePTFE graft surfaces over the 60 min of the flow period. There were no significant differences between the surface coatings
