DNA Methylation and Regulatory Elements during Chicken Germline Stem Cell Differentiation

In this study, we reported a comprehensive genome-wide DNA methylation landscape in chicken germ cells, and transcriptomic dynamics was also presented. By uncovering DNA methylation patterns on individual genes, some genes accurately modulated by DNA methylation were found to be associated with cancers and virus infection, e.g., AKT1 and CTNNB1. Chicken-unique markers were also discovered for identifying male germ cells. Importantly, integrated epigenetic mechanisms were explored during male germ cell differentiation, which provides deep insight into the epigenetic processes associated with male germ cell differentiation and possibly improves treatment options to male infertility in animals and humans. Graphical abstract Teaser In this article, Song, Li, and their colleagues reported a comprehensive genome-wide DNA methylation landscape in chicken germ cells. The integrated epigenetic mechanisms were explored, specifically, germ cell differentiation experiences through a highly orchestrated process that involves multiple epigenetic events, which would give a clue for curing male infertility in animals and humans.
