Thrombocyte adhesion and aggregation in a hypodysfibrinogenemia model. (A) Fluorescent thrombocyte binding and adhesion in 5 dpf Tg(itga2b:EGFP) embryos after laser injury of the PCV over time in fga+/+, fga+/Δ19–56 and fgaΔ19–56/Δ19–56 genotypes. Each line represents the mean (+/−SEM) of thrombocyte fluorescence reaching a threshold fluorescence within a defined area. (B) Time lapse images of fga+/+ and fgaΔ19–56/Δ19–56 larvae upon (0 s) and 180 s after laser injury. Fluorescence from the laser is seen at 0 s and where green fluorescent thrombocytes accumulate at 180 s. The dorsal aorta (DA), posterior cardinal vein (PCV) and site of laser injury (LI, arrows) are indicated.
