Abstract:
:Megakaryocytic colony formation by progenitor cells of 18 patients with polycythaemia vera, seven with secondary erythrocytosis and four with erythrocytosis of unexplained origin was studied in vitro by the methyl cellulose culture assay. Fourteen of the 18 patients with polycythaemia vera showed spontaneous megakaryocytic colony formation, i.e. colony growth with normal human plasma as the only source of colony stimulation. None of the patients with secondary erythrocytosis or erythrocytosis of unknown origin or of the normal controls grew colonies in the presence of normal human plasma only. When the plasma of a patient with aplastic anaemia was used instead of normal human plasma and phytohaemagglutinin stimulated leucocyte conditioned medium (PHA-LCM) was added to the culture medium, two of the patients with polycythaemia vera and one with secondary erythrocytosis formed slightly increased numbers of megakaryocytic colonies, while the rest of the patients showed normal colony formation. All of the patients with polycythaemia vera but none of those with secondary erythrocytosis or erythrocytosis of unknown origin showed spontaneous erythroid colony growth. The present study shows that most patients with polycythaemia vera form spontaneous megakaryocytic colonies in vitro. This phenomenon has recently also been demonstrated in essential thrombocythaemia and it is apparently analogous to spontaneous erythroid colony growth seen in all myeloproliferative disorders.
