Megakaryocyte apoptosis in immune thrombocytopenia
The mechanisms of platelet underproduction in immune thrombocytopenia (ITP) remain unknown. While the number of megakaryocytes is normal or increased in ITP bone marrow, further studies of megakaryocyte integrity are needed.

Megakaryocyte-erythroid lineage promiscuity in EKLF null mouse blood [PDF]
Commitment towards megakaryocyte versus erythroid blood cell lineages occurs in the megakaryocyte-erythroid progenitor, where mutually exclusive expression of either EKLF (Klf1) or Fli1 defines alternative outcomes.

DNMT3A regulates murine megakaryocyte-biased hematopoietic stem cell fate decisions
: Hematopoietic stem cells (HSCs) are defined by their capacity to regenerate all main components of peripheral blood, but individual HSCs exhibit a range of preferences for generating downstream cell types.

Megakaryocyte emperipolesis: a new frontier in cell-in-cell interaction
Histology of bone marrow routinely identifies megakaryocytes that enclose neutrophils and other hematopoietic cells, a phenomenon termed emperipolesis.

MicroRNA function in megakaryocytes
Megakaryocytes (MKs), the largest cells in the bone marrow, are generated from hematopoietic stem cells (HSCs) in a sequential process called megakaryocytopoiesis in which HSCs undergo MK-progenitor (MP) commitment and maturation to terminally ...

The determination of megakaryocyte ploidy
Methods which have been used to determine megakaryocyte ploidy in animals and humans are reviewed. Although the number of megakaryocyte nuclear units counted in bone marrow squashes is roughly proportional to ploidy, accurate determinations of DNA content require the use of microphotometry or flow cytometry.

CD34+ megakaryocytes and megakaryocytic fragments in myelodysplastic syndrome [PDF]
![Figure][1] A 65-year-old woman presented with fatigue and exertional dyspnea. The peripheral blood showed: hemoglobin, 91 g/L; leukocytes, 4.8 × 109/L with 1% blast cells; and platelets, 35 × 109/L with megakaryocytic fragments (panel A, filled black arrow; original magnification ×100;

Lineage tracing of Pf4-Cre marks hematopoietic stem cells and their progeny [PDF]
The development of a megakaryocyte lineage specific Cre deleter, using the Pf4 (CXCL4) promoter (Pf4-Cre), was a significant step forward in the specific analysis of platelet and megakaryocyte cell biology.

Acute megakaryoblastic leukemia of Down syndrome (DS-AMKL) is a model of clonal evolution from a preleukemic transient myeloproliferative disorder requiring both a trisomy 21 (T21) and a GATA1s mutation to a leukemia driven by additional driver mutations.
