Prophaseis the first phase of mitosis. During this phase, the chromosomes inside the cell's nucleus condense and form tight structures. In fact, the chromosomes become so dense that they appear as curvy, dark lines when viewed under a microscope (Figure 1). Because each chromosome was duplicat...
We first analysed mitosis in polarized MDCK cells by live-cell imaging and found that MDCK cells complete mitosis within B60 min (Fig. 3a). To test whether Cdc42 acts downstream of JAM-A in the regulation of spindle orientation, MDCK cells were synchronized to G2/M phase transition using ...
英语翻译原文:Process of MeiosisUnlike the single-cell division of mitosis,meiosis involves two cellular divisions:meiosis I and meiosis II.Each stage of meiosis runs through the same five stages as discussed in mitosis.During the first round
The surface distribution of ConA also varied dramatically as a function of mitotic phase. Between mid-prophase and early anaphase, the pattern of surface ConA-receptor complexes is diffuse. Once the cleavage furrow begins to develop, however, ConA moves into the region of the furrow. This was ...

Chromosome velocity has been studied in living Melanoplus differentialis spermatocytes by phase contrast cinemicrography. Melanoplus chromosomes (and bivalents) differ in length by as much as 1:3.5. As expected, no size-dependent velocity differences were detected in anaphase, and this is also shown...
During mitosis, not only the genetic material stored in the nucleus but also the constituents of the cytoplasm should be equally partitioned between the daughter cells. For this sake, the dividing cell goes through an extensive structural reorganization and transport along the endocytic and exocytic ...
The liver is unique in its ability to regenerate from a wide range of injuries and diseases. Liver regeneration centers around hepatocyte proliferation and requires the coordinated actions of nonparenchymal cells, including biliary epithelial cells, live
Moreover, cells that enter mitosis with damaged DNA encounter segregation problems because of their abnormal chromosomes, leading to defects in mitotic exit, and they therefore accumulate in G1 phase. These multi- or micronucleated cells are prevented from cycling again in a p53- and p21-...
