Did you know?

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. WebThe number of circulating reticulocytes is higher in mice (200–500 × 10 9 /L) than in most other species, due to the short lifespan of the mouse red blood cell. Units for reticulocyte count vary among laboratories, but generally are reported in the same units as red blood cells or in the same units as platelets (cells × 10 9 /L).
