myeloblast[′mī·ə·lō‚blast] (histology) The youngest precursor cell for blood granulocytes, having a nucleus with finely granular chromatin and nucleoli and intensely basophilic cytoplasm. myeloblastenUK
myeloblast [mi´ĕ-lo-blast″] an immature cell of bone marrow, not normally found in peripheral blood; it is the most primitive precursor in the granulocytic series, which develops into the promyelocyte and eventually into a granulocyte.my·e·lo·blast (mī'ĕ-lō-blast), An immature cell (10-18 mcm in diameter) in the granulocytic series, occurring normally in bone marrow, but not in the circulating blood (except in certain diseases). When stained with the usual dyes, the cytoplasm is light blue, nongranular, and variable in amount, sometimes being only a thin rim around the nucleus; the latter is deep purple-blue with finely divided, punctate, threadlike chromatin that is somewhat condensed at the periphery. A few light blue nucleoli are usually present in the nucleus, and these generally disappear as the myeloblast matures into a promyelocyte and then a myelocyte. Myeloblasts ordinarily yield a negative reaction with peroxidase. [myelo- + G. blastos, germ] myeloblast (mī′ə-lə-blăst′)n. An immature cell of the bone marrow that is the precursor of a myelocyte.
my′e·lo·blas′tic adj.my·e·lo·blast (mī'ĕ-lō-blast) An immature cell in the granulocytic series, occurring normally in bone marrow but not in the blood. When stained, the cytoplasm is light blue and variable in amount; the nucleus deep purple-blue with finely divided, punctate, threadlike chromatin. A few light blue nucleoli in the nucleus generally disappear as the myeloblast matures into a promyelocyte and then a myelocyte. [myelo- + G. blastos, germ]myeloblast The bone marrow cell from which the whole series of granular white blood cells (GRANULOCYTES) derives. Up to 3% of bone marrow cells are myeloblasts.myeloblastenUK
