Analysis of Wnt3+/+ and Wnt3-/- embryonic stem cell-induced, pluripotent epiblast-like cells stimulated with cytokines (BMP4, Wnt3a, or BMP4+Wnt3a) for up to 36 hrs to induce primordial germ cells (PGCs). Results provide insight into molecular mechanisms by which BMP4/WNT3 signaling specifies PGCs.

(Submitter supplied) Germ cells ensure reproduction and heredity in metazoans. Primordial germ cells (PGCs) in mice are induced in pluripotent epiblasts by BMP4 and WNT3, yet their mechanism of action remains unclear. Here, using in vitro PGC specification system, we show that WNT3 induces many transcription factors associated with mesoderm in epiblast-like cells (EpiLCs) through b-CATENIN. Among these, T (BRACHYURY), a classical and conserved mesodermal factor, was essential for robust activation of Blimp1 and Prdm14, two of the germline determinants. more...

(Submitter supplied) The germ cell lineage ensures the continuity of life through the generation of male and female gametes, which unite to form a totipotent zygote. We have established a culture system that recapitulates the mouse germ-cell specification pathway: Using cytokines, embryonic stem cells (ESCs)/induced pluripotent stem cells (iPSCs) are induced into epiblast-like cells (EpiLCs) and then into primordial germ cell-like cells (PGCLCs) with capacity both for spermatogenesis and oogenesis, creating an opportunity for understanding and regulating mammalian germ cell development in both sexes in vitro. more...

(Submitter supplied) Oct4 is an essential regulator of embryonic stem (ES) cell pluripotency in vivo and in vitro, as well as a key mediator of the reprogramming of somatic cells to form induced pluriopotent stem (iPS) cells. It is not known whether activation and/or repression of specific genes by Oct4 is relevant to these functions. Here we show that fusion proteins containing the coding sequence of Oct4 or Xlpou91 (the Xenopus homologue of Oct4) fused to activating regions, but not those fused to repressing regions, behave as Oct4, suppressing differentiation and promoting maintenance of undifferentiated phenotypes in vivo and in vitro. more...

(Submitter supplied) Nanog, a core pluripotency factor in the inner cell mass of blastocysts, is also expressed in unipotent primordial germ cells (PGC) in mice1, where its precise role is yet unclear2-4. We investigated this in an in vitro model, where naïve pluripotent embryonic stem cells (ESCs) cultured in bFGF/ActivinA develop as epiblast-like cells (EpiLCs), and gain competence for PGC-like fate5. Consequently, bone morphogenetic protein (BMP4), or ectopic expression of key germline transcription factors Prdm1/ Prdm14/ Tfap2c, directly induce PGC-like cells (PGCLCs) in EpiLCs, but not in ESCs6-8. more...

(Submitter supplied) Germ cell specification is accompanied by epigenetic remodeling, the scale and specificity of which are unclear. Here, we quantitatively delineate chromatin dynamics during induction of mouse embryonic stem cells (ESCs) to epiblast-like cells (EpiLCs) and from there into primordial germ cell-like cells (PGCLCs), revealing large-scale reorganization of chromatin signatures including H3K27me3 and H3K9me2 patterns. more...

(Submitter supplied) We re-analyzed gene expression in the primordial germ cell (PGC) specification pathway in vitro, by using previously deposited microarray data. The germ cell lineage produces either spermatozoa or oocytes and, by their fusion, creates zygotes with full developmental potential, thereby perpetuating and diversifying organisms' genetic as well as epigenetic information across generations. In mice, PGCs are specified in the most posterior part of epiblast (monolayer epitherium-like cells, from which the whole embryonic part of conceptus will be derived) around embryonic day (E) 6.25 by a cytokine BMP4. more...

(Submitter supplied) Blimp1 (Prdm1), the key determinant of primordial germ cells (PGC), plays a combinatorial role with Prdm14 during PGC specification from postimplantation epiblast cells. They together initiate epigenetic reprogramming in early germ cells towards an underlying pluripotent state, which is equivalent to embryonic stem cells (ESC). Whereas Prdm14 alone can promote reprogramming and is important for the propagation of the pluripotent state, it is not known if Blimp1 is similarly involved. more...

(Submitter supplied) The molecular mechanisms of human primordial germ cell (PGC) specification are poorly understood due to the inaccessibility of cell materials and the lack of an alternative in vitro model that enables tracking of the earliest stages of germ cell development. Here, we introduce a defined and efficient differentiation system for the induction of pre-migratory PGC-like cells from human embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs). more...

(Submitter supplied) Specification to primordial germ cells (PGCs) occurs under the mesoderm induction signals during gastrulation. Here, we found that Akt activation in embryonic stem (ES) cells generated self-renewing spheres during mesodermal differentiation induction and that the differentiation status of the sphere cells was in between ES cells and PGCs. Essential regulators for PGC specification and their downstream germ cell-specific genes were expressed in the spheres, showing that the cells of the sphere commenced the differentiation to germ lineage. more...

(Submitter supplied) Epiblast stem cells (EpiSC) are pluripotent stem cells derived from mouse postimplantation embryos between E5.5 to E7.5, a time window in which gastrulation commences. Therefore, EpiSC represent a valuable tool for studying mammalian postimplantation development in vitro. Beyond their pluripotent features, EpiSC can also be reprogrammed into a mouse embryonic stem cell-like (mESC) state. Published reports showed that EpiSC reversion requires transcription factor overexpression, while others suggest that applying stringent mESC culture conditions alone was sufficient to revert EpiSC to mESC-like cells. more...
