Effect of FIX deficiency on mouse TG in WB and PPP. TG in both WB and PPP of F9^+/+ control mice and F9^−/− mice were triggered by 120× diluted silica or 0.05/0.5 pM TF and recalcification (4 μM phospholipids were added in PPP). Representative curves of WB- and PPP-TG are shown in (A) and (E), respectively. Bar graphs of lag time (B,F), peak height (C,G), and ETP (D,H) are shown as median (n = 6 mice per group). Comparisons between groups were made using the Mann-Whitney test. ∗P < .05; ∗∗P < .01.
