We found that p-CENP-A was phosphorylated at late prophase, and the signal of p-CENP-A arranged at equatorial plate along with nucleosomes at metaphase, but moved to midbody at later phase of mitosis. The phosphorylation modification of CENP-A shares some characters of H3, but has ...

Prophase, which is the first stage of mitosis, is characterized by the appearance of centrosomes. When viewed under the microscope, they are a pair of tiny spots/dots surrounded by a clear region. In prometaphase, the nuclear envelope begins to break down as the chromosomes start interacting ...
However, it was in 1876 that Walter Fleming used staining techniques to stain and identify chromatin. This allows him to study cell division more closely in a process that he named mitosis. In 1888, his colleague, Heinrich Wilhelm Gottfried von Waldeyer-Hartz continued studying the stained ...
Microscopically, a tumor consists of epithelial cells with round, basophilic, uniform nucleus, inconspicuous nucleoli, and pale eosinophilic granulated cytoplasm. The architectural pattern was trabecular, ribbonlike, and partly acinar. No significant cytologic atypia, mitosis, and necrosis were present. H...
Given that ciliated cells are not capable of mitosis, these indices suggest that NE cells are also mostly quiescent. Several groups, including ours, have reported that Notch signaling plays a key role in NEB development (Ito et al., 2000, Morimoto et al., 2012, Tsao et al., 2009). We...

Recent work has unveiled many of the mechanisms that govern the localization of cyclin-B1–Cdk1 and its regulator Cdc25C. Phosphorylation-dependent changes in the rate of nuclear import and export of these proteins help to control the onset of mitosis both in normal cells and in cells delayed...
In both species, one or two prominent nucleoli were apparent within interphase nuclei stained with either silver nitrate or a fluorescent dye YOYO-1. However, a single large nucleolus was observed in early stages of mitosis and meiosis I regardless the number of rDNA clusters. Nevertheless, two ...
These adhesions were observed to be confined to relatively narrow areas near the cell margins, principally in the vicinity of ruffling activity. During mitosis and after certain treatments, cell-substratum adhesion was found to be restricted to many tiny points connected to the cell body by narrow...
