Dasatinib induces reversible thrombocytopenia in mice. (A) Whole-blood platelet count from control mice (solid line) and dasatinib-treated (5 mg/kg/d) mice (dashed line) were monitored every day for 7 days. Error bars represent SEM; **P < .01; n = 5 for each time point. (B) Whole-blood platelet count from control mice (solid line) and dasatinib-treated (5 mg/kg/d) mice (dashed line) were monitored 2 and 4 days after interruption of the drug. Error bars represent SEM; **P < .01; n = 3 for each time point.
