Multicycle algorithm-based quantification of the amounts of MCF7-wt and MCF7-si cells in the G0/G1, the S and the G2/M phase of the cell cycle. Results are shown both for confluently growing control cells and for cells analyzed at various time points after trypsination and (re-) seeding. Values represent average ± SD (n = 3). * Indicates p < 0.05 vs. MCF-wt.
