myelopoiesis

 [mi″ĕ-lo-poi-e´sis]
the formation of marrow or the cells arising from it.
ectopic myelopoiesis (extramedullary myelopoiesis) formation of myeloid tissue outside bone marrow.

my·e·lo·poi·e·sis

(mī'ĕ-lō-poy-ē'sis),
Formation of the tissue elements of bone marrow, or any of the types of blood cells derived from bone marrow; or both processes.
[myelo- + G. poiēsis, a making]

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.

In Visceral leishmaniasis marrow shows several changes which includes presence of LD bodies decreased myeloid-erythroid ratio indicating relative suppression of myelopoiesis, increased number of plasma cells, presence of giant metamyelocytes indicating suppression of cell division, presence of juvenile megakaryocytes signifying increased formation of platelets to meet demand caused by increased destruction in hyperactive spleen, presence of micronormoblasts in aggregates indicating splenic hyperactivity and crenated LD bodies with deformed cell membranes in cases of treated kala-azar.11 The cases diagnosed with visceral Leishmaniasis in this study depicted some of the changes like plasma cell prominence and increased number of macrophages.
