Erythropoietin. Erythropoietin is a hormone, produced mainly in the kidneys, which stimulates the production and maintenance of red blood cells. Medical Definition of Hormone, erythropoietin These cells release erythropoietin when the oxygen level is low in the kidney. Erythropoietin stimulates the bone marrow to produce more red blood cells which in turn increases the oxygen-carrying capacity of the blood. EPO is the prime regulator of red cell production. Endocrine functions of the kidneys. The kidneys produce three important hormones: erythropoietin, calcitriol (1, 25- dihydroxycholecalciferol ) and renin. They also synthesize prostaglandins, which affect many processes in the kidneys. Leukopoiesis. Leukopoiesis, the process of making leukocytes, is stimulated by various colony-stimulating factors (CSFs), which are hormones produced by mature white blood cells. Hematopoiesis is the production of all of the cellular components of blood and blood plasma. It occurs within the hematopoietic system, which includes organs and tissues such as the bone marrow, liver, and spleen. Simply, hematopoiesis is the process through which the body manufactures blood cells.

What happens if I have too much erythropoietin? Excess erythropoietin results from chronic low oxygen levels or from rare tumours that produce high levels of erythropoietin. It causes a condition known as polycythaemia which is a high red blood cell count. In many people, polycythaemia does not cause any symptoms.

Manipulating diet for protein and total calorie adequacy, monitoring hydration, using supplements, timing food combinations, adding weekly hypoxic exercise followed by easy or rest days all increases the release of natural EPO for healthy maximal oxygen carrying capacity.

The normal range for EPO levels can vary from 3. 7 to 36 international units per liter (IU/L). Higher-than-normal levels may mean you have anemia. In severe cases of anemia, EPO levels in the blood may be a thousand times higher than normal. Unusually low levels may be because of polycythemia vera.

Erythropoietin. Erythopoietin is a protein hormone essential to production of red blood cells (erythrocytes), which themselves deliver oxygen to all tissues in the body. This hormone is synthesized in the kidney and its secretion is regulated by the amount of oxygen delivered to that organ.

Common side effects may include: increased blood pressure; joint pain, bone pain, muscle pain; itching or rash; fever, chills, cough; mouth pain, trouble swallowing; nausea, vomiting; headache, dizziness; trouble sleeping;

When kidneys don't have enough oxygen, they produce a protein called erythropoietin (EPO), which stimulates red blood cell production. “We have figured out how mammals know to turn on that EPO. ” The new knowledge could apply to diseases characterized by hypoxia, such as pulmonary hypertension.

Erythropoietin is produced by interstitial fibroblasts in the kidney in close association with the peritubular capillary and proximal convoluted tubule. It is also produced in perisinusoidal cells in the liver.

Medication to stimulate RBC production: A hormone called erythropoietin is produced in the kidneys and liver and stimulates the bone marrow to produce RBCs. Erythropoietin can be used as a treatment for some forms of anemia.

Leukopoiesis is a form of hematopoiesis in which white blood cells (WBC, or leukocytes) are formed in bone marrow located in bones in adults and hematopoietic organs in the fetus.

Blood cells do not originate in the bloodstream itself but in specific blood-forming organs, notably the marrow of certain bones. In the human adult, the bone marrow produces all of the red blood cells, 60–70 percent of the white cells (i. e., the granulocytes), and all of the platelets.

In the blood, two types of white blood cells, neutrophilic leukocytes (microphages) and monocytes (macrophages), are phagocytic. Neutrophils are small, granular leukocytes that quickly appear at the site of a wound and ingest bacteria.

The bone marrow produces stem cells, the building blocks that the body uses to make the different blood cells – red cells, white cells and platelets. The erythropoietin sends a message to the stem cells telling more of them to develop into red blood cells, rather than white cells or platelets.

Hematopoiesis is the continuous, regulated process of renewal, proliferation, differentiation, and maturation of all blood cell lines. These processes result in the formation, development, and specialization of all functional blood cells that are released from the bone marrow into the circulation.
