ABSTRACT
Pluripotent stem cell lines established from early-stage embryos of mammals or other species represent the embryonic stages before the initiation of somatic development. In these stem cell lines, cell proliferation capacity is maintained while developmental progression is arrested at a specific developmental stage that is determined by the combination of culture conditions, cell state, and species. All of these pluripotent stem cell lines express the transcription factors (TFs) Sox2 and Pou5f1 (Oct3/4); hence, these TFs are often regarded as pluripotency factors. However, the regulatory roles of these TFs vary depending on the cell line type. The cell lines representing preimplantation stage embryonic cells (mouse embryonic stem cells, mESCs) are regulated principally by the combined action of Sox2 and Pou5f1. Human ESCs and mouse epiblast stem cells (EpiSCs) represent immature and mature epiblast cells, respectively, where Otx2 and Zic2 progressively take over the preimplantation stage's regulatory roles of Sox2 and Pou5f1. This transition of the core TFs occurs to prepare for the initiation of somatic development.
