查询词典 doubling

A strain of breast tumor cell line ZHL2006 was established and biologically identified. The ZHL2006 cells grew fast in vitro and the population doubling time was 43.6h. Electronmicroscopical observation showed that there were microvilli on the surface of the cells, nucleus irregularity, karyoplasmic ratio increased, nucleolus distinctness, et al.. Chromosome number and structure were abnormal. Immunohistochemistry showed that PCK were expressed. The ZHL2006 cell line could form onto clone in soft agar and had oncogenicity in athymic mice.

In mixoploid plants, somatic cells with 2n=25~29 were most frequent except for a few haploid cells (2n=19) and chromosome doubling cells (2n=50~60). Abnormal chromosome behaviors were observed in pollen mother cells from mixoploid BI-1 and haploid, including chromosome bridges, laggard chromosomes, meiotic cycle asynchrony and unequal separation of chromosomes.
