Fig. 4: Genome-wide DNA demethylation in cancer cells is strongly enriched in heterochromatin regions.

a Global DNA methylation levels (1 kb tile) of single cells in each subclone of P11. b Genome-wide DNA demethylation heatmap (10 Mb window) of cancer cells compared to all Norm_epi cells in P11. c Spearman correlations between DNA demethylation levels and the densities of genomic landmarks under different resolutions in each patient.
