Study Notes
Erythropoiesis Stimulation and Location
- Hypoxia, or oxygen deficiency, stimulates erythropoiesis
- In postnatal birds and mammals, erythropoiesis usually occurs in the bone marrow
Fetal Erythropoiesis
- In the early fetus, erythropoiesis takes place in the yolk sac and later in the liver and spleen
Hormonal Regulation
- Erythropoietin (EPO) stimulates the proliferation and differentiation of red cell precursors
Erythropoiesis Increase
- Increased altitude, anemia, and chronic lung disease can cause an increase in erythropoiesis
