myelopoiesis

[mī′əlō′pō·ē′sis]
Etymology: Gk, myelos + poiein, to form
the formation and development of bone marrow or the cells that originate from it. A kind of myelopoiesis is extramedullary myelopoiesis. myelopoietic [-pō·et′ik] , adj.

myelopoiesis

The production of myeloid cells in the bone marrow; more generically, myelopoiesis refers to the production of any cell line (erythroid, megakaryotic, myelocytic) in the bone marrow.

1,2) Clues to the morphologic diagnosis of SMAHNMD include abnormal peripheral blood cell counts and morphology, hypercellularity of the bone marrow, signs of dysplasia or abnormal myelopoiesis, increased number of blasts (Figure 2, A and B), and abnormal lymphoid or plasma aggregates or interstitial infiltrates.
In myelopoiesis, ALP production in neutrophils is induced by G-CSF, and NAP is released into the bloodstream, perhaps through leakage of ALP from damaged or dead neutrophils.
Histology carried out in October 1999 revealed a normocellular bone marrow with prominent myelopoiesis, but there was no morphologic evidence for dyshematopoiesis and/or an increased blast cell count; no chromosomal abnormality was detectable.
The most important differential is generally with transient abnormal myelopoiesis, which has a similar phenotype, although expression of CD11b and CD13 is more common in the leukemia form.
