WebThe mitotic phase is a relatively short period of the cell cycle. It alternates with the much longer interphase, where the cell prepares itself for the process of cell division. Interphase is divided into three phases: G 1 (first …
Web31 mrt. 2009 · We studied the mitotic activity of the multinucleated cells by Ki-67 immunohistochemistry, ... Some of these multinucleated cells are considered to be neoplastic and possess atypical nuclei or mitotic changes . However, it is not known precisely by what mechanism multinucleated cells are formed. WebOn average, the mitoses counted by two observers were 13% and 10% below initial values after 3 hours, and decreased by 46% and 39% after 12 hours. The mitosis decrease was related to the degree of mitotic activity of individual tumors, and was minimal in the sarcomas with the lowest mitotic rate. These results were reproducible.
WebMitotic catastrophe has been observed in response to treatment with a variety of genotoxic agents that have different mechanisms of action (Table 22.1).These data demonstrate that mitotic catastrophe is an important and widely observed mode of death in response to treatment with genotoxic agents [58].It is likely that these cells undergo checkpoint …
