metamyelocyte
A cell similar in shape, but slightly smaller (10 to 16 µm in diameter) than a myelocytes, which has a central or eccentric, indented kidney bean nucleus. The chromatin is usually coarsely clumped, and there is no nucleolus; the N:C ratio is 1.5:1 to 1:1. The abundant, pink or colourless cytoplasm may contain rare reddish-purple azurophilic (primary) granules and/or many fine, lilac, neutrophilic (secondary/specific) granules.The metamyelocyte corresponds to the M5 stage of a maturing granulocyte, which is morphologically between a myelocyte (M3 or M4) and a PMN (M6 or M7).
