- 1. A mature white blood cell in the granulocytic series, formed by myelopoietic tissue of the bone marrow (sometimes also in extramedullary sites), and released into the circulating blood, where they normally represent 54–65% of the total number of leukocytes. When stained with the usual Romanovsky type of dyes, neutrophils are characterized by 1) a nucleus that is dark purple-blue, lobated (three to five distinct lobes joined by thin strands of chromatin), and with a rather coarse network of fairly dense chromatin; and 2) a cytoplasm that is faintly pink (sharply contrasted with the nucleus) and contains numerous fine pink or violet-pink granules, i.e., not acidophilic or basophilic (as in eosinophils or basophils). The precursors of neutrophils, in order of increasing maturity, are: myeloblasts, promyelocytes, myelocytes, metamyelocytes, and band forms. Although the terms neutrophilic leukocytes and neutrophilic granulocytes include younger cells in which neutrophilic granules are recognized, the two expressions are frequently used as synonyms for neutrophils, which are mature forms unless otherwise indicated by a modifying term, such as immature n.. SEE ALSO: leukocyte, leukocytosis. 2. Any cell or tissue that manifests no special affinity for acid or basic dyes, i.e., the cytoplasm stains approximately equally with either type of dye. [neutro- + G. philos, fond]- hypersegmented n. an aged and degenerated n. in which there may be 6 to 10 lobes in the nucleus.- immature n. a young n.; the term is usually used with reference to stab neutrophils (or other “juvenile” neutrophils), neutrophilic granulocytes in which the nucleus is indented but not distinctly segmented.- juvenile n. any cell of the granulocytic series in which the neutrophilic granules are recognizable and the nucleus is indented (the first phase of segmentation).- mature n. SYN: segmented n..- segmented n. a fully matured n. that has at least 2 (and as many as 5) distinct lobes in the nucleus and manifests active ameboid motion. SYN: mature n..
