n.
The formation or production of red blood cells.

erythropoiesis

[erith′rōpō·ē′sis]
Etymology: Gk, erythros + poiein, to make
the process of erythrocyte production in the bone marrow involving the maturation of a nucleated precursor into a hemoglobin-filled, nucleus-free erythrocyte that is regulated by erythropoietin, a hormone produced by the kidney. Compare erythrogenesis. See also erythrocyte, erythropoietin, hemoglobin, leukopoiesis. erythropoietic, adj.

e·ryth·ro·poi·e·sis

(ĕ-rith'rō-poy-ē'sis)

[erythrocyte + G. poiēsis, a making]

erythropoiesis

Red cell production.

erythropoiesis

the formation of blood cells in bone marrow.

Erythropoiesis

The process through which new red blood cells are created; it begins in the bone marrow.
Mentioned in: Porphyrias

erythropoiesis

the formation of red blood cells (erythrocytes) from stem cells in the bone marrow. Regulated by the hormone erythropoietin from the kidneys, where increased secretion is stimulated by reduced oxygen tension in the blood; a recombinant human form is used therapeutically to treat some types of anaemia.

erythropoiesis

erythropoiesis (i·rith·rō·poiˑ·ē·sis),

n red blood cell production that occurs in bone marrow and involves maturation of nucleated precursors into erythrocytes regulated by the hormone erythropoietin produced in the kidneys.

e·ryth·ro·poi·e·sis

(ĕ-rith'rō-poy-ē'sis)
Formation of red blood cells.
[erythrocyte + G. poiēsis, a making]

erythropoiesis (ərith´rōpoiē´sis),

n the process in which red blood cells are formed.

erythropoiesis

the formation of erythrocytes. Called also hematopoiesis.

balanced erythropoiesis
balanced progressive development of the nucleus and the cytosol of the erythrocytes.
ineffective erythropoiesis
hemopoietic production which does not result in the functional release of new erythrocytes.

Ineffective erythropoiesis in beta-thalassemia is characterized by increased iron absorption mediated by downregulation of hepcidin and up-regulation of ferroportin.
Hemosiderosis in thalassemia is secondary to frequent transfusions and increased iron absorption associated with ineffective erythropoiesis.
Transferrin receptor concentrations are increased in disorders with expanded erythropoiesis, such as hemolytic anemias [15, 16, 18], and in conditions associated with ineffective erythropoiesis, such as myelodysplastic syndromes and megaloblastic anemias [21, 22].
We are very excited by these new data with ALN-TMP where we have demonstrated disease modifying effects in models of -thalassemia, including amelioration of anemia, iron overload, extra-medullary hematopoiesis, and ineffective erythropoiesis, in addition to correction of globin gene expression.
