Megakaryoblast - Wikipedia
网页A megakaryoblast (from mega- 'large' karyo- 'cell nucleus' and -blast 'precursor cell') is a precursor cell to a promegakaryocyte. During thrombopoiesis, the promegakaryocyte matures into the form of a megakaryocyte. From the megakaryocyte, platelets are formed. [1]
Megakaryoblast - an overview | ScienceDirect Topics
网页A Megakaryoblast is defined as the predominant component of the blast population in the bone marrow and/or peripheral blood, displaying pleomorphic characteristics ranging from small, round cells to large cells with cytoplasmic blebs and prominent nucleoli.

网页The megakaryoblast, or stage I megakaryocyte, is a more mature cell that has a distinct morphology. 18 The megakaryoblast has a kidney-shaped nucleus with two sets of chromosomes (4 N).

网页Megakaryoblast. In subject area: Biochemistry, Genetics and Molecular Biology. Unlike megakaryocyte progenitors, which possess a high proliferative potential, megakaryocytes are cells that have lost the ability to proliferate but instead undergo a unique process known as endomitosis.
The secret life of a megakaryocyte: emerging roles in bone marrow ...
网页2015年1月9日 · Megakaryocytes are rare cells found in the bone marrow, responsible for the everyday production and release of millions of platelets into the bloodstream.
Megakaryopoiesis and Platelet Biology: Roles of Transcription …
网页2021年9月5日 · Introduction. Platelets are small, anucleate blood cells produced from mature bone marrow megakaryocytes [1]. In humans, the reference range for normal platelet count is 150–400 × 10 9 /L, and its life span is 8–12 days. Approximately 10 11 platelets are generated daily, suggesting that a robust differentiation process is required [2].
The biology of pediatric acute megakaryoblastic leukemia
网页2015年8月8日 · Acute megakaryoblastic leukemia (AMKL) is a subtype of acute myeloid leukemia (AML) characterized by abnormal megakaryoblasts that express platelet-specific surface glycoprotein. Bone marrow biopsy frequently demonstrates extensive myelofibrosis, often making aspiration in these patients difficult.
The bone marrow niche from the inside out: how megakaryocytes …
网页2022年1月27日 · Megakaryocytes (MKs), the largest of the hematopoietic cells, are responsible for producing platelets by extending and depositing long proplatelet extensions into the bloodstream. The traditional view of megakaryopoiesis describes the cellular journey from hematopoietic stem cells (HSCs) along the myeloid branch of hematopoiesis.
