mineral required for erythropoiesis
Red Blood Cell Production
Red blood cell (RBC) production (erythropoiesis) takes place in the bone marrow under the control of the hormone erythropoietin (EPO). Juxtaglomerular cells in the kidney produce erythropoietin in response to decreased oxygen delivery (as in anemia or hypoxia) or increased levels of androgens. In addition to erythropoietin, red blood cell …
Regulation of erythropoiesis
The production of erythrocytes is a tightly regulated process. During steady state hematopoiesis, approximately 10 10 red blood cells are produced per hour in the bone marrow to maintain the hemoglobin level within fairly narrow limits. Production can be rapidly increased in the setting of ongoing blood loss or hemolysis.

Heme Metabolism and Erythropoiesis
Further work is required to determine a role for PCBP1 in vertebrate erythropoiesis. Alternatively, a second model – termed the "kiss and run" hypothesis – argues that Fe 2+ -containing endosomes home to and directly contacts the mitochondria, allowing Fe 2+ to be transferred without exposure to the cytosol [ 15** ].
Biochemistry, Iron Absorption
