Iron is an essential functional component of hemoglobin. Using a mouse model, researchers found that erythroferrone is made by red blood-cell progenitors in the bone marrow in order to match iron supply with the demands of red blood-cell production. Erythroferrone is greatly increased when red blood-cell production is stimulated, such as after bleeding or in response to anemia.'} created: Mon, 02 Jun 2014, 08:53 AM UTC
