(A) Blood clotting profile and; (B) hemolysis percentage of lumen surface of P:P and P:P:Bs vascular grafts. (C) Platelets that have attached to grafts (shown by the red arrows) after being incubated with fresh human PRP for 1 h with the different groups of vascular grafts. Scale bar = 20 and 5 μm. Data presented as mean ± SD, n = 3, all statistical significance shown in comparison to control graft (P:P) unless otherwise stated, ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001.
