title: Megakaryocytes and inherited thrombocytopenias.
abstract: Inherited thrombocytopenias may be divided into two groups. In the first group, there is no marked thrombocytopathy. Although numerous in the bone marrow, megakaryocytes often are abnormal cytologically. A dysmegakaryocytopoiesis with defective platelet production is suggested but remains to be evidenced. In the second group, thrombocytopenias are accompanied with variable thrombocytopathy. The functional and biochemical platelet abnormalities responsible for these different thrombocytopathies often are well elucidated. The study of the relations with the occurrence of thrombocytopenia constitutes an interesting field of investigation.
