Promyelocyte - Wikipedia
Promyelocytes are essential players in the body's immune system, serving as precursors to mature granulocytes involved in host defense and inflammatory responses. Understanding the characteristics, functions, and clinical significance of promyeloctes is crucial for the diagnosis, management, and treatment of various hematologic disorders.
How to tell apart promyelocytes and myelocytes
The promyelocyte is the biggest cell in the neutrophil series. It also has huge, dark purple, primary (azurophilic) granules both in the cytoplasm and overlying the nucleus. However, it does NOT have the beginnings of secondary (specific, pink, salmon-colored) granulation!
Promyelocyte Number and Ratio - Glossary | Laboratory ... - Biron
Promyelocytes are rarely observed and, if seen, are often a sign of blood cancer. Results are expressed as the number (#) of promyelocytes and, more usefully, as the ratio of promyelocytes (fraction of white cells made up of promyelocytes).
Promyelocyte - an overview | ScienceDirect Topics
Promyelocytes are large cells with prominent nucleoli, a Golgi hof, and primary granules. The promyelocytes of the three granulocytic lineages cannot be distinguished by routine light microscopy. Myelocytes no longer have nucleoli and now contain secondary, or specific, granules that do now allow the three granulocytic lineages to be distinguished.

Promyelocyte - an overview | ScienceDirect Topics
A promyelocyte is a larger cell than a myeloblast, with prominent nucleoli, a Golgi hof, and granules. These granules are primary granules and appear reddish-purple. The promyelocytes of the three granulocytic lineages cannot be distinguished by routine light microscopy.
Neutrophil promyelocyte - CellWiki
A promyelocyte is a relatively large cell with a round or oval, eccentrically located nucleus in which one or more nucleoli can be seen. The cytoplasm is dark blue/purple with often a single brightening at the edge of the nucleus (golgi zone). The dark blue colored granules lie both in the cytoplasm and over the nucleus.
Promyelocyte vs. Myelocyte — What’s the Difference?
2024年3月13日 · A promyelocyte (or progranulocyte) is a granulocyte precursor, developing from the myeloblast and developing into the myelocyte. Promyelocytes measure 12-20 microns in diameter.
Promyelocyte - an overview | ScienceDirect Topics
A promyelocyte is an immature cell found in the bone marrow, specifically in the myeloid line of cells, characterized by an excess of these cells in acute promyelocytic leukemia (APL). AI generated definition based on: Systems Biology and its Application in …
Promyelocyte - American Society of Hematology
2016年2月17日 · Promyelocytes comprise approximately 2% of nucleated cells in the bone marrow and do not circulate in peripheral blood under normal conditions. Promyelocytes are larger than myeloblasts, and have basophilic cytoplasm containing primary (azurophilic) granules. A Golgi zone may be visible as a.
