WebA comparative study of circulating human reticulocytes by phase-contrast microscopic observation and NMB staining revealed two different forms of reticulocytes which could be clearly distinguished by their distinctive morphologic appearance. These were (1) a multilobular motile form and (2) a cup-shaped nonmotile form. Reticulocytes 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.
