What is Normoblastic erythropoiesis?
Erythropoiesis. A significant amount of heme is synthesized by normoblasts (also known as erythroblasts) in the bone marrow during erythropoiesis. In mammals, erythropoiesis also takes place in the mesoderm of the yolk sac of the early fetus and in the liver of midterm fetuses.
