Mouse trophectoderm stem cells generated with morula signalling inducers capture an early trophectoderm state

Nature Cell Biology
The first embryonic cell differentiation in mice segregates the trophectoderm and the inner cell mass. Successful derivation of mouse trophoblast stem cells (TSCs) and trophectoderm stem cells (TESCs) has greatly facilitated the understanding of trophoblast differentiation.

Automatic Segmentation of Trophectoderm in Microscopic Images of Human Blastocysts

IEEE Transactions on Biomedical Engineering, 2015
Accurate assessment of embryos viability is an extremely important task in the optimization of in vitro fertilization treatment outcome. One of the common ways of assessing the quality of a human embryo is grading it on its fifth day of development based on morphological quality of its three main components (Trophectoderm, Inner Cell Mass, and the ...

Differentiation of ICM cells into trophectoderm.

The American journal of pathology, 1988
It has been established previously that when inserted in the blastocyst E Ca 247 preferentially differentiates into trophectoderm in vitro. If the concept that tumors are caricatures of the process of tissue renewal is correct, then some cells from the inner cell mass (ICM), the normal counterpart of embryonal carcinoma, should be able to differentiate

Junctional composition of the trophectoderm.

We measured total transcription in the inner cell mass (ICM) and the trophectoderm (TE) of the human embryo to understand the mechanisms underlying TE commitment. We describe here identification of genes located at cellular junctions with contributory functions as lineage commitment cooperating factors in embryonic stem cells of the human embryo.

In Vitro Attachment and Outgrowth of Mouse Trophectoderm

1981
Implantation of a mammalian embryo into the uterine lining is a morphodynamic process that is accompanied by marked changes in cellular architecture and subcellular organization. In order to determine the extent to which such changes are mandated by factors external to the embryo, we have examined surface and intracellular changes in fine structure ...

Golgi and glycosylation function in the trophectoderm.

We measured total transcription in the inner cell mass (ICM) and the trophectoderm (TE) of the human embryo to understand the mechanisms underlying TE commitment. We describe here discovery of genes with functions in glycosylation as important for lineage commitment in embryonic stem cells of the human embryo, including Poglut3.

Trophectoderm biogenesis in the preimplantation mouse embryo

1992
The trophectoderm epithelium is the first tissue to differentiate during mammalian development. It constitutes the wall of the spherical blastocyst and, after implantation, is the source of the major extra-embryonic lineages of the conceptus, notably trophoblastic giant cells, extra-embryonic ectoderm, ectoplacental cone and chorionic ectoderm ...
