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.
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.
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 - 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
In normal promyelocytes, the retinoic acid binds the retinoic acid receptor (RAR) that forms a heterodimer with retinoid x receptor (RXR). This binding causes the heterodimer to from a corepressor (CoR) and bind a coactivator (CoA) leading to expression of genes necessary for differentiation into mature neutrophils.

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.

急性早幼粒细胞白血病 （acute promyelocytic leukemia，APML，APL）又稱 急性前髓細胞白血病，是一种亚型 急性骨髓性白血病 [1]。 1957年，法国和挪威的医生首次提到急性早幼粒细胞白血，當時患者的生存期不到一周 [2]。 隨新藥發明與演進，預後已大大改善；現今患者的10年生存率估计约为80-90% [3][4]。 急性早幼粒細胞白血病的特徵是染色體易位，涉及 17号染色体 (RARA) 上的 视黄酸受体α 基因 [1]。 95% 的 APL 病例中，17號染色體上的維甲酸受體-α (RARA) 基 …
