Erythropoiesis

• • In adults, erythropoiesis occurs primarily within the red marrow of bones. Erythropoietin (EPO) regulates this process
• Erythropoiesis refers specifically to the formation of erythrocytes
• Erythropoiesis begins early in embryonic development
• In adults, the red bone marrow is the primary site of blood cell formation
• In extreme conditions, the fatty yellow bone marrow in other bones can be converted to red bone marrow
• Vitamin B is a vitamin obtained from dairy products and meat
• Erythropoiesis is regulated by the hormone erythropoietin (EPO)
• Erythropoietin has two effects:

  • stimulates cell division rates in erythroblasts and in stem cells that produce erythroblasts
  • Speeds the maturation of RBC
