Did you know?
Webmegakaryocyte (MK)/platelet lineage is the most complex among hematopoietic cell lines. Not only is the MK itself unique because of its enor- mous size and polyploidy, but it also produces its progeny, the platelets, by a unique mechanism, i.e., cytoplasmic fragmentation. Although platelets have no nucleus and usually lack ribosomes, they WebCompact, lobulated megakaryocyte nuclei, apparently denuded of cytoplasm (naked nuclei), have been reported to be markedly increased in the bone marrow of persons …
WebWhy cells do not have a nucleus? Nucleus is necessary for the cell as it controls the gene expression and other metabolic activities. Let us find out the reasons why cells do not have a nucleus. ... Platelets are formed by fragmentation of huge nucleus of bone marrow. A single megakaryocyte can produce up to 1000-3000 platelets. WebThey have a single nucleus and deeply basophilic cytoplasm (Fig. 8-12, A). This cell type is not recognized in most normal aspirate smears because it occurs in small numbers and is difficult to differentiate from other blast cells. ...

WebMar 10, 2016 · Megakaryopoiesis is the process by which a hematopoietic progenitor cell (HPC) differentiates into a large polyploid megakaryocyte, whereas thrombopoiesis is … A megakaryocyte (mega- + karyo- + -cyte, "large-nucleus cell") is a large bone marrow cell with a lobated nucleus responsible for the production of blood thrombocytes (platelets), which are necessary for normal blood clotting. In humans, megakaryocytes usually account for 1 out of 10,000 bone marrow … See more In general, megakaryocytes are 10 to 15 times larger than a typical red blood cell, averaging 50–100 μm in diameter. During its maturation, the megakaryocyte grows in size and replicates its DNA without cytokinesis in … See more Platelet release Once the cell has completed differentiation and become a mature megakaryocyte, it begins the process … See more In 1906, James Homer Wright provided evidence that megakaryocytes give rise to blood platelets. Kelemen first coined the term "thrombopoietin" to describe the humoral substance responsible for the production of platelets. See more Megakaryocytes are derived from hematopoietic stem cell precursor cells in the bone marrow. They are produced primarily by the liver, kidney, spleen, and bone marrow. These multipotent stem cells live in the marrow sinusoids and are capable of … See more Megakaryocytes are directly responsible for producing platelets, which are needed for the formation of a thrombus, or blood clot. There are several diseases that are directly attributable to abnormal megakaryocyte function or abnormal platelet function.
