The mean DNA content of megakaryocytes is at levitra dosage least eight times that of other somatic cells. Megakaryocytes are mainly found in the bone marrow but can transit to many organs, including the lung, where part of the platelet release occurs. The formation and release of platelets is related to a preformed structure in the cytoplasm of megakaryocytes, the so-called “demarcation membrane system.” Megakaryocytes derive from megakaryocyte progenitors (CFU-Mega, see Fig.
Which in turn originate in the hematopoietic stem cell, 1.1). One megakaryocyte can produce at least several thousand platelets. The maturation of megakaryocytes and the production of platelets occurs under the influence of thrombopoietin (TPO.
