Thus, our data indicate that Stat3 and Stat5 may be involved in signal transduction after ligand binding to c-Mpl and that this event may have a role in megakaryopoiesis/ thrombopoiesis or possibly a mature platelet function such as aggregation .
 ( protein: c-Mpl, None) , ( protein: Stat5, None) , ( protein: Stat3, None)
