Pluripotent stem cells (PSCs) can be differentiated into all three germ layers in vitro. The pluripotent stem cells are derived from the inner cell mass of blastocyst in vitro, termed embryonic stem cells (ESCs). The epiblast derived pluripotent stem cells (Epi- SCs) represent a more differentiated state than plurioptent ESCs. The pluripotent ESCs and EpiSCs express Oct4 (Pou5f1) gene. Oct4 gene is essential for maintenance of pluripotent ESCs. The pluriopotent ESCs are induced differentiation into trophectoderm by decreasing Oct4 levels below 50%. Oct4 levels regulate cell fate of pluripotent stem cells. Here, we established ZHBTc4-ESCs derived epiblast stem cells like cells (ZHBTc4- EpiLCs). ZHBTc4-EpiLCs could not be maintained in doxycycline (dox) contained EpiSC medium, indicated that Oct4 gene is essential for maintenance of primed EpiLCs. We also tried to differentiate ZHBTc4-EpiLCs into neuroectoderm or mesoendoderm lineages with or without dox. The ZHBTc4-EpiLCs could be efficiently differentiated into neuroectoderm lineage with dox, whereas these cells could not be differentiated into mesoendoderm lineage with dox. This results showed that Oct4 gen
