Global DNA demethylation in humans is a fundamental process that occurs in pre-implantation embryos and reversion to naïve ground state pluripotent stem cells (PSCs). However the extent of DNA methylation reprogramming in human germline cells is unknown. Here we performed whole-genome bisulfite sequencing (WGBS) and RNA-sequencing (RNA-Seq) of human prenatal germline cells from 53–137 days of development. We discovered that the transcriptome and methylome of human germline is distinct from both human PSCs and the inner cell mass (ICM) of human blastocysts. Using this resource to monitor the outcome of global DNA demethylation with reversion of primed PSCs to the naïve ground state, we uncovered hotspots of ultralow methylation at transposons that are protected from demethylation in the germline and ICM. Taken together the human germline serves as a valuable in vivo tool for monitoring the epigenome of cells that have emerged from a global DNA demethylation event.
