A karyotypic characterization of subteraploid and a modal number of 74 - 77 have been revealed in this cell line. All cells contained a series of non- random chromosomal rearrangements. 18 of them, including 5 isochromosomes. were present in all metaphases and 3 of them in a few one. These findings indicated that the severe DNA damage and increase of gene copies may be occurred in genome of HNE- 1 cells.展开更多
