Trophoblast stem cells (TSCs) arise from the first cell fate decision in the developing embryo and generate extra-embryonic lineages, giving rise to the fetal portion of the placenta. Mouse embryonic and extra-embryonic lineages are strictly separated by a distinct epigenetic barrier, which is not fully overcome following expression of TSC-determining(More)
Trophoblast stem cells (TSCs) are in vitro equivalents to the precursor cells of the placenta. TSCs are cultured in serum-rich medium with fibroblast growth factor 4, heparin, and embryonic-fibroblast-conditioned medium. Here, we developed a simple medium consisting of ten chemically defined ingredients for culture of TSCs on Matrigel or synthetic(More)
In mammals, the first cell fate decision is initialized by cell polarization at the 8- to 16-cell stage of the preimplantation embryo. At this stage, outside cells adopt a trophectoderm (TE) fate, whereas the inside cell population gives rise to the inner cell mass (ICM). Prior to implantation, transcriptional interaction networks and epigenetic(More)
In recent years, knowledge regarding the genetic and epigenetic programmes governing specification, maintenance and differentiation of the extraembryonic lineage has advanced substantially. Establishment and analysis of mice deficient in genes implicated in trophoblast lineage and the option to generate and manipulate murine stem cell lines from the inner(More)
Recently, direct cell fate conversion attempts between the embryonic and extra-embryonic lineage gained new momentum. Two concomitant publications were published, describing the successful generation of transgene-independent, self-renewing trophoblast stem cells (TSCs) from murine fibroblasts. Cells were faithfully converted, displaying high similarity to(More)
Loss of TFAP2C in mouse leads to developmental defects in the extra-embryonic compartment with lethality at embryonic day (E)7.5. To investigate the requirement of TFAP2C in later placental development, deletion of TFAP2C was induced throughout extra-embryonic ectoderm at E6.5, leading to severe placental abnormalities caused by reduced trophoblast(More)
Researchers at the University of Cambridge, UK have succeeded in reconstructing mouse embryos by combining pluripotent embryonic and multipotent trophoblast stem cells in a 3D scaffold; the study from the laboratory of Professor Zernicka-Goetz, recently published in Science, provides a break-through tool to probe early mammalian development outside the(More)
Trophoblast stem cells (TSCs) arise as a consequence of the first cell fate decision in mammalian development. They can be cultured in vitro, retaining the ability to self-renew and to differentiate into all subtypes of the trophoblast lineage, equivalent to the in vivo stem cell population giving rise to the fetal portion of the placenta. Therefore, TSCs(More)
