Megakaryocyte — Wikipedia Republished // WIKI 2, Megakaryocyte – an overview | ScienceDirect Topics, Megakaryocyte – an overview | ScienceDirect Topics, Megakaryocyte – Wikipedia, Megakaryocytes are the hematologic progenitors that give rise to platelets in the bone marrow when associated with endothelial structures. Several groups recently have shown that megakaryocytes are direct regulators of hematopoietic stem cell quiescence.
The megakaryocyte develops through the following lineage: CFU-Me (pluripotential hemopoietic stem cell or hemocytoblast) -> megakaryoblast -> promegakaryocyte -> megakaryocyte . The cell eventually reaches megakaryoblast stage and loses its ability to divide. However, it is still able to replicate its DNA and continue development.
1/1/2019 · Eventually , the megakaryocyte is transformed into a residual naked nuclei surrounded by an anastomosing network of proplatelet processes. Megakaryocyte maturation ends when a rapid retraction separates the proplatelet fragments from the cell body releasing them into culture (Fig. 2.6, asterisk at 10 h). The subsequent rupture of the cytoplasmic bridges between platelet-size segments is thought to.
What does a megakaryocyte eventually become ? A. erythrocyte B. Eosinophil C. Thrombocyte D. Neurtophil, 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.
Megakaryocyte development and platelet formation are regulated at multiple levels by many cytokines, including thrombopoietin , stromal cell-derived factor 1, Interleukin-3, 6, and 11, and stem …
10/30/2017 · • Question 3 1 out of 1 points A megakaryocyte will eventually produce Selected Answer: a. thrombocytes. Response Feedback: The megakaryocyte is the multinucleated cell in the red bone marrow off which platelets will separate. Erythrocytes, monocytes, and neutrophils all develop from their own specific stem cells. • Question 4 1 out of 1 points, Which of the following types of formed elements is produced when a megakaryocyte fragments? Basophil Neutrophil Platelet Erythrocyte
