Table 1.

Cell population fractions (%). Cumulative frequency distributions were examined to extract cell cycle and ploidy sub-populations. Diploid fraction corresponds to a DNA normal 2C non-cycling DNA content. Diploid S fractions have DNA content between diploid and tetraploid values. The tetraploid sub-population contains both diploid G2/M cells and tetraploid G1 cells. The cells with DNA content between tetraploid and octaploid are S-phase tetraploid cells, Octaploid DNA content cells are the G2/M cells of the tetraploid population.
