Effects of α2AP deficiency on chronic thrombus formation. (A) Martius scarlet blue-stained 7-day-old thrombi (scale bar = 500 µm). (B) Magnified images (original magnification ×20) of IVC thrombus showing lamellate fibrin-rich (pink) lines of Zahn. (C) Thrombi were not formed in α2AP−/− mice after 7 days of IVC ligation. Arrow indicates the minimum thrombus formation. (D) Martius scarlet blue stained 14 days old thrombi (scale bar = 500 µm) in α2AP+/+ mice. (E) Magnified image (original magnification ×20) of panel D showing a fibrin-rich (pink), porous thrombus. (F) Martius scarlet blue-stained IVC showing minimum thrombus in α2AP−/− mice. (G) Representative images of IVC thrombus formation in different groups as labeled including sham mice (7 days). (H) Vein thrombus weight milligram/gram of body weight. Each symbol represents an animal used in each group (N = 38). One-way ANOVA; ****P < .0001, **P < .01.
