The nucleus is round or oval, and the nuclear chromatin is diffuse, as in the myeloblast. The nucleoli tend to become less prominent as the cell develops. The azurophilic or primary granules appear at this stage, but the secondary granules are not yet present.

Webb4 mars 2015 · It is often possible at the myelocyte stage to see the area of the Golgi apparatus, which appears as a clearing close to the nucleus. The specific secondary granules differentiate the cell into neutrophil, eosinophil, and basophil. The nucleus then begins to indent and chromatin becomes coarser, signaling the metamyelocyte stage. WebbThe organelles involved in the production of granules, i.e., the nuclear envelope, rough endoplasmic reticulum, and Golgi apparatus, are peroxidase positive during the eomyolocyte and promyelocyte stages and peroxidase negative thereafter.
