title: Early mouse embryo development: could epigenetics influence cell fate determination?
abstract: It is generally assumed that the developmental program of embryogenesis relies on epigenetic mechanisms. However, a mechanistic link between epigenetic marks and cell fate decisions had not been established so far. In a recent article, Torres-Padilla and colleagues show that epigenetic information and, more precisely, histone arginine methylation mediated by CARM1 could contribute to cell fate decisions in the mouse 4-cell-stage embryo. It provides the first indications that global epigenetic information influences allocation of pluripotent cells toward the first cell lineages.
