hematopoiesis

 [he″mah-to-poi-e´sis]
the formation and development of blood cells. In the embryo and fetus it takes place in a variety of sites including the liver, spleen, thymus, lymph nodes, and bone marrow; from birth throughout the rest of life it is mainly in the bone marrow with a small amount occurring in lymph nodes. Called also hematogenesis, hemogenesis, and hemopoiesis.
extramedullary hematopoiesis the formation and development of blood cells outside the bone marrow, as in the spleen, liver, and lymph nodes.

he·mo·poi·e·sis

(hē'mō-poy-ē'sis),
The process of formation and development of the various types of blood cells and other formed elements.Synonym(s): hematosis (1)
[hemo- + G. poiēsis, a making]

It is interesting to note here the role of microbial metabolites on hematopoiesis. Josefsdottir et al.
In vitro, BMSCs were shown to support long-term hematopoiesis [9].
Ghrelin produced this effect by enhancing migration of lymphoid precursors from the bone marrow by activating GHS-R-specific pathway19, suggesting role of ghrelin in stimulation of hematopoiesis.
Some miRNAs were chosen because of their reported roles in hematopoiesis mechanisms (table 1).
Additionally, lymphocytes produce IL-6, a cytokine that plays an important role in hematopoiesis stimulation to promote hematological recovery [17].
Based on our previous report on transcription factor Gfil and cell surface marker CD48 in murine myeloid hematopoiesis [23], we evaluated CD48 as a marker to effectively distinguish granulocytic MDSCs from monocytic MDSCs in septic mice.
Head and neck examination revealed depressed cranial vault, frontal bossing, retracted upper lip, and saddle nose (severe face deformity due to extramedullary hematopoiesis).
Extramedullary hematopoiesis (EMH) occasionally occurs in patients exhibiting hematological disorders with decreased hematopoietic efficacy, such as myelofibrosis, thalassemia, and polycythemia vera.
The company added that myelodysplastic syndromes are a complex and heterogeneous group of bone marrow failure disorders characterised by ineffective hematopoiesis and poor prognosis.
The analytical units (XN-10) provide a comprehensive CBC and differential along with advanced measures of hematopoiesis through advanced, reportable parameters: automated IG, NRBC (with every CBC), reticulocyte hemoglobin RET-He and immature reticulocyte fraction (IRF), immature platelet fraction (IPF) and fluorescent platelet count (PLT-F) and automated body fluid count (with a 2-part differential).
