WebJun 1, 2024 · In general, reticulocytes mature within one day of being released from bone marrow; however, in the setting of stress erythropoiesis, as in a high erythropoietin level (eg, in persons with severe anemia), reticulocytes are prematurely released from bone marrow to the blood circulation, increasing the number of days that reticulocytes stay … WebReticulocytes are immature red blood cells (RBCs). In the process of erythropoiesis (red blood cell formation), reticulocytes develop and mature in the bone marrow and then circulate for about a day in the blood stream before developing into mature red blood cells. Like mature red blood cells, in mammals, reticulocytes do not have a cell nucleus.
