In patients the response of reticulated platelets to ADP is inhibited to a greater extent by ticagrelor than by clopidogrel. The reticulated platelet subpopulation among nonaggregated single platelets was assessed by flow cytometry in platelet-rich plasma incubated with vehicle, ADP, or arachidonic acid (AA). Samples were obtained from patients taking (A) ticagrelor or (B) clopidogrel (in addition to aspirin). Representative flow cytometric images of ADP-stimulated platelet aggregates (platelets red; mRNA green) formed in samples from patients taking aspirin plus (C) ticagrelor or (D) clopidogrel. Scale bars, 7 μm. Data presented as individual data points with overlaid mean±SEM and compared by paired t test (n=9–10; ***P<0.001).
