Megakaryocyte cultures in the chronic phase and in the blast crisis of chronic myeloid leukaemia: studies on the differentiation of the megakaryocyte progenitors and on the maturation of megakaryocytes in vitro.
Megakaryocyte (MK) colony formation has been studied in the chronic phase and in the blast crisis of chronic myeloid leukaemia (CML). Blood cells were grown in plasma clot for 13 d. MKs were subsequently identified by immunofluorescent techniques using two monoclonal antiplatelet antibodies (AN51 and J15). The maturation process was studied by ultrastructural methods. A marked increase in the number of circulating CFU-MK was observed in all the 10 cases studied prior to chemotherapy (70-fold ...Expand abstract
