Identification of tissue-specific DMRs spanning large chromosomal domains. (A) A breast-specific hypomethylated region containing multiple noncoding RNA genes. (Green box) ∼75-kb region hypomethylated in all breast cell types (luminal [Lum], myoepithelial [Myo], and stem cell-enriched [BSC]). (Red box) Hypermethylation events within the same region in the HCC1954 breast tumor cell line. (B) A large H1 ESC-specific hypermethylated chromosomal domain spanning the PCDHG gene cluster. (Orange box) H1 ESC-specific hypermethylated DMRs in the vicinity of the promoters of several PCDHG gene family members.
