Similar to other haematopoietic cells, megakaryocytes originate from haematopoietic stem cells. Proliferation and maturation of the megacaryotic cell line is stimulated by a number of factors. This process is different in progenitor and precursor cells. Towards the end of their development, mature megakaryocytes are transferred and are localized near the bone marrow sinus wall. "Proplatelets" are formed in cytoplasmic extensions of megakaryocytes and are subsequently separated from parental megacaryocyte and transformed into platelets in the circulation.

Keywords: thrombocytes; megakaryopoesis; thrombopoesis
