mitoses in English

noun

1

a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.

It is generally assumed that DNA chains are randomly segregated to daughter cells during mitosis .

Use "mitoses" in a sentence

1. In this grouping of cells haploid, diploid and sometimes triploid mitoses appear.

2. Interphase --- The stage of the cell cycle between two successive mitoses.

3. In Comedo, DCIS cells are large with pleomorphic nuclei and abnormal mitoses

4. In tissue cultures from an abortus (empty sack, containing fluid) all countable mitoses indicate a tetraploid chromosome complement (92/XXXX).

5. The cytogenetic studies demonstrated that the mitoses achieved by culture techniques were aneuploid and, thus, there is evidence that they are of leukaemic origin.

6. This can be seen in anaphase figures as well as in interphase nuclei presumably derived from tripolar mitoses, showing chromocenters according to the number of X-chromosomes.

7. The histologic determination of the degree of tissue anaplasia and grade of malignancy of gliomas is based upon qualitative histological features (nuclear pleomorphism, mitoses, endothelial proliferation, tumor necrosis).

8. Synchronous mitoses without cell wall formation and mitotic disturbances (f. i. anaphase arrest leading to restitution nuclei, fusion of spindles) are responsible for these cells with polyploid and lobed nuclei.

9. An aneuploid chromosomal anomaly was observed in more than 90% of the mitoses of a spontaneous acute lymphatic leukaemia in C57BL/6 J mice preserved by passage in the strain of origin since 1967.

10. The parameters “percentage of dicentric chromosomes”, “breaks”, and “excess acentric fragments” in comparison to the total number of mitoses analyzed could neither serve as meaningful nor as significant criteria, since they showed a strong interindividual variability.

11. The LD50 of colchicine in mice bearing HD33 ascites tumors was 1.4 mg/kg body weight (b.w.), but a single dose of 3.33 mg colchicine/kg b.w. failed to suppress the anaphase of HD33 tumor mitoses for 24h.

12. In the 2nd half of the cycle, during pregnancy, during antiovulatory treatment and in postmenopausal period, the endosalpingeal epithelium of pars of uterina, isthmus, ampulla and infundibulum is characterized by proliferative quiescence (i.e. lack of mitoses, a small quantity of nuclei, a simple epithelium).

13. The detailed analysis was focused on the number of breaks per metaphase, on breaks from complex chromosomal rearrangements per metaphase, as well as on the percentage of translocations, dicentric chromosomes, breaks, and excess acentric fragments—each in comparison with the total number of mitoses analyzed.
