Detailed explanation-1: -Neutrophil maturation progresses from the progranulocyte stage through myelocyte, metamyelocyte, band and mature neutrophil stages, with each successive division resulting in slightly smaller cell with more nuclear constriction and less cytoplasmic RNA (blue color in cytoplasm).
Detailed explanation-2: -Metamyelocytes, together with myelocytes and promyelocytes, are precursors of neutrophils, the largest class of white blood cell. These immature neutrophils are normally found only in the bone marrow. In the blood, it is metamyelocytes that are the most often observed, accompanied by a few myelocytes.
Detailed explanation-3: -Early granulocyte precursors (myeloblast and promyelocyte) appear similar between the various granulocytic cell lines until the myelocyte stage, which is the final stage capable of cell division. At this stage, they develop characteristic secondary lineage-specific granules (neutrophilic, eosinophilic or basophilic).
