when cells from the extremes of the phi distribution were sorted using a fluorescence-activated cell sorter and then restained for cellular dna content , it was found that the higher phi values were associated with enrichment of the s , g2 , and m phases of the cell cycle , with a corresponding increase in the percentage of g1 cells at the lower ph1 range , suggesting cell-cycle dependence of phi .
