text: Cell lines derived from such post-implantation epiblasts are referred to as epiblast-derived stem cells which were first derived in laboratory in 2007; despite their nomenclature, that both ESCs and EpiSCs are derived from epiblasts, just at difference phases of development, and that pluripotency is still intact in the post-implantation epiblast, as demonstrated by the conserved expression of Nanog, Fut4, and Oct-4 in EpiSCs, until somitogenesis and can be reversed midway through induced expression of Oct-4.
