Abstract:
Although mutations in cell cycle regulators or spindle proteins can perturb chromosome segregation1–7 the causes and consequences of spontaneous mitotic chromosome nondisjunction in human cells are not well understood.

Keywords:
mutation; spontaneous mitotic chromosome nondisjunction; mitosis; aneuploid; tetraploid; chromosome mis-segregation; furrow regression; cancer

Materials & Methods:
HeLa or N/TERT-1 cells expressing GFP–histone 2B were grown on gridded coverglass bottom dishes (MatTek CatNo. P35G-1.5-7-C-grid) for 26 h (HeLa 2 £ 105 cells per dish) or 3 d (N/TERT-1 4 £ 104 cells per dish) before imaging.
