FIGURE 2.

Drug-resilient cells exhibit one to two whole-genome duplications with high fidelity. A, Copy numbers in untreated and treated surviving HCC1806 cells 5 DPT, as visualized with AneuFinder (reads per 10 Mb over total amount of reads) from scWGS each row representing a single nucleus. B, Ratio of DNA content within each cell in untreated and surviving HCC1806 cells 5 DPT. The heat maps show the normalized read depth (reads per 10 Mb bins over total amount of reads in the cell) of scWGS, where blue areas show a lower number of reads, and red areas show a higher number of reads. The blocks R1, R2, and R3 in the left represent replicates 1, 2, and 3, respectively. C, Copy number of chromosome X in untreated (CTL), surviving HCC1806 cells at 5 DPT and their progeny, as visualized with chromosomal FISH of cells in interphase.
