CGH profiles of 11 MCF-7 sublines. Copy number alterations are indicated as bars on each side of the chromosome ideograms, losses are shown by bars on the left, gains on the right. Each bar corresponds to an event observed in one subline. Events indicated by dotted lines corresponded to gains or losses reproducibly observed but whose fluorescence ratios did not reach the significance thresholds (1.3 or 0.75). Bars have been ordered from left to right for gains and from right to left for losses. The relative order was (1) MCF-7-R, (2) MCF-7-R-D4, (3) MCF-7-R-G1, (4) MCF-7-R-F3, (5) MCF-7-MVLN, (6) MCF-7-6ms7, (7) MCF-7-6ms8, (8) MCF-7-MF, (9) MCF-7-O, (10) MCF-7-MG, (11) MCF-7-ATCC.
