Mouse Embryonic Stem Cells (ESC) can be derived from internal cellular mass of blastocyst in pre and post-implantation, originating, respectively, mESC or EpiSCs. In vitro, these cells present different functional, phenotypic, epigenetic and molecular characteristics. The mESC (Naïve) are considered more primitive and undifferentiated, meanwhile the EpiSCs (Primed) would be already prepar…
