Figure 6From: Selective impairment of methylation maintenance is the major cause of DNA methylation reprogramming in the early embryo Summary of DNA methylation changes in primordial germ cells (PGCs) and pre-implantation embryos. (A) Absolute DNA methylation levels and (B) percentage of hemimethylated CpG dyads in relation to all methylated CpG dydas (red, L1Md_Tf (L1); blue, major satellites (mSat); green, IAPLTR1 (IAP)). Note that from 13.5 dpc PGCs to the two-cell stage the values are depicted separately for maternal and paternal chromosomes, respectively, and thereafter depicted as combined values.Back to article page
