WebPromyelocytes and myelocytes lack nucleoli and exhibit elevated chromatin condensation compared to myeloblasts. An indented nucleus is characteristic of a metamyelocyte. The band cell nucleus is shaped like a horseshoe and it constricts to form nuclear lobes, while segmented neutrophils are distinguishable by their segmented nucleus, with three to … The nuclear chromatin is coarser than that observed in a promyelocyte, but it is relatively faintly stained and lacks a well-defined membrane. The nucleus is fairly regular in contour (not indented), and seems to be 'buried' beneath the numerous cytoplasmic granules. Meer weergeven A myelocyte is a young cell of the granulocytic series, occurring normally in bone marrow (can be found in circulating blood when caused by certain diseases).
