Erythropoiesis is a highly regulated, multistep process in which stem cells, after a series of amplification divisions, generate multipotential progenitor cells, then oligo- and finally unilineage erythroid progenitors, and then morphologically recognizable erythroid precursors and mature red cells.

Ontogeny of erythropoiesis—this involves a series of well-coordinated events during embryonic and early fetal life: (1) embryo—the fetal yolk sac makes embryonic haemoglobins; (2) fetus—the main site of erythopoiesis is the liver, which initially produces mainly fetal haemoglobin (Hb F, ...
