Figure Lengend Snippet: Fibrinogen binding and aggregation of Itgb3 −/− platelets. (A) Fibrinogen binding of washed platelets from three types of mice (Itgb3 +/+ , Itgb3 +/− and Itgb3 −/− mice) under stimulation by agonists, including ADP, AF, or Mn 2+ , with or without the inhibitor RGDS. (B) Whole blood aggregation of Itgb3 +/+ and Itgb3 −/− mice under stimulation of 2 µg/ml thrombin, 6 µg/ml collagen or 12 µg/ml collagen. Calcein AM-labeled whole blood from Itgb3 +/+ mice and Itgb3 −/− mice was perfused over a collagen-coated surface at shear rates of 1,500 s −1 and images were captured under (C) bright-field at the indicated time points and (D) fluorescence microscope at 4.5 min. Arrows indicated the adhered platelets. ADP, adenosine diphosphate; AF, Ala-Tyr-Pro-Gly-Lys-Phe (AYPGKF); Itgb3, integrin β3; RGDS, Arg-Gly-Asp-Ser.
