The cell in the center of the field is a myelocyte. It is the last stage of the series that will undergo division. The N:C ratio of myelocytes usually varies from 2:1 - 1:1. The nucleus is usually eccentric; the shape is regular, round, oval, or sometimes even triangular. The nuclear chromatin is coarser and more clumped than that of promyelocytes. The cytoplasm is normally pink or light blue or a mixture of the two. Myelocytes are the stage at which specific granules appear and azurophilic granules seem to disappear. However, it is only a color change from red to colorless.
