Thrombopoietin stimulated blast colony formation in 11/20 acute myelogenous leukaemia (AML) patients studied. The FAB subtypes of the blasts responding to thrombopoietin were not restricted to those of the megakaryocyte lineage, but also included M1-M5 AML blasts. The morphology of colony cells produced by megakaryocytic blasts showed megakaryocytoid features, whereas colony cells produced by M1-M5 AML blasts remained myeloblasts. An increase in CD41 was observed in the cells of colonies produced by blasts from the megakaryocyte lineage involving leukaemia and chronic myeloid leukaemia in blastic crisis. Thrombopoietin receptor was observed on leukaemic blasts which formed colonies following incubation with thrombopoietin.
