Part Description

LP15077-8   Myelocytes
The identification of mature and immature granulocytes, including myelocytes and metamyelocytes, in blood and bone marrow is fundamental to the diagnosis of haematological disorders. A myelocyte is a young cell of the granulocytic series, occurring normally in bone marrow, but not in circulating blood (except when caused by certain diseases). Myelocytes are derived from promyelocytes and give rise to metamyelocytes. When stained with the usual dyes, the cytoplasm in myelocytes is distinctly basophilic and relatively more abundant than in myeloblasts or promyelocytes. Numerous cytoplasmic granules are present in the more mature forms of myelocytes. Neutrophilic and eosinophilic granules are peroxidase-positive, while basophilic granules are not. The nucleus of a myelocyte is fairly regular in contour (not indented), and seems to be 'buried' beneath the numerous cytoplasmic granules. If the nucleus were indented, it is likely be a metamyelocyte. Copyright Text is available under the Creative Commons Attribution/Share-Alike License.
