  2. Megakaryocyte - Wikipedia

    en.wikipedia.org/wiki/Megakaryocyte

    In either scenario, each of these proto-platelet processes can give rise to 2000–5000 new platelets upon breakup. Overall, 2/3 of these newly produced platelets will remain in circulation while 1/3 will be sequestered by the spleen.

  3. Thrombopoiesis - Wikipedia

    en.wikipedia.org/wiki/Thrombopoiesis

    This includes self-renewal and expansion of hematopoietic stem cells, stimulating the increase of megakaryocyte progenitor cells, and supporting these cells so they mature to become platelet-producing cells. [2] The process of thrombopoiesis is caused by the breakdown of proplatelets (mature megakaryocyte membrane pseudopodial projections ...

  4. Thrombopoietin - Wikipedia

    en.wikipedia.org/wiki/Thrombopoietin

    Theoretical uses include the procurement of platelets for donation, [9] and recovery of platelet counts after myelosuppressive chemotherapy. [ 5 ] Trials of a modified recombinant form, megakaryocyte growth and differentiation factor (MGDF), were stopped when healthy volunteers developed autoantibodies to endogenous thrombopoietin and then ...

  5. Megakaryoblast - Wikipedia

    en.wikipedia.org/wiki/Megakaryoblast

    During thrombopoiesis, the promegakaryocyte matures into the form of a megakaryocyte. From the megakaryocyte, platelets are formed. [1] The megakaryoblast is the beginning of the thrombocytic series or platelet forming series. Megakaryoblasts typically have a large oval-shaped nucleus or a nucleus that is lobed with many nuclei. [2]

  6. Platelet - Wikipedia

    en.wikipedia.org/wiki/Platelet

    Platelets derive from multipotent marrow stem cells. Megakaryocyte and platelet production is regulated by thrombopoietin, a hormone produced in the kidneys and liver. Each megakaryocyte produces between 1,000 and 3,000 platelets during its lifetime. An average of 10 11 platelets are produced daily in a healthy adult.

  7. Plateletpheresis - Wikipedia

    en.wikipedia.org/wiki/Plateletpheresis

    Platelets collected by using apheresis at an American Red Cross donation center. Not all platelet transfusions use platelets collected by automated apheresis. The platelets can also be separated from donations of whole blood collected in a traditional blood donation, but there are several advantages to separating the platelets at the time of collection.
