Microgamonts have superficial small nuclei with homogenate nucleoplasm
and without nucleoli, numerous dense inclusions, vacuoles and few amylopectin granules.
In any stage, the nurse cells present large nuclear masses of thread-like eletrondense material disperse in the nucleoplasm
and attached to the nuclear envelope (Figure 3c); as these masses increase in size and number, the nuclei becomes irregular.
nucleus The subcellular structure within a cell that contains the chromosomes, nucleolus, and nucleoplasm
Finally, toward the middle of the organ, the shape of the nucleus changes from ovoid to plano-convex, the nucleoplasm
becomes more homogeneous, and the subnuclear cytoplasm assumes the vesiculated appearance of a mature photocyte [ILLUSTRATION FOR FIGURE 34 OMITTED].
These modifications affect the transcriptional activity, DNA binding affinity and localization of FOXO1 transcriptional factor in nucleoplasm
or cytoplasm (Van Der Heide et al.
Viable neurons were microscopically identified by the presence of typical nuclei with the clear nucleoplasm
and a distinct nucleolus, surrounded by purple-stained cytoplasm.
Nuclei in the subrhabdomeric layer ceaselessly pass through the basal lamina into the inner segment with development (Plate 1 and Plate 6-32), become a little slender than those of the nuclei in inner segment cells, and have very electron-dense nucleoplasm
with many patches of heterochromatin (Plate 6-32).
We can harpoon the nucleus, pull out all of the nucleoplasm
on a string in interphase or pull out all the chromosomes on a string in metaphase, then add a small amount of magnesium, and all these structures unwind.
Most of the staining was concentrated along the nuclear membranes with some condensed staining within the nucleoplasm
Results indicate spermatogonia have a central, spherical nucleus as well as scattered heterochromatin granules throughout the nucleoplasm
