trophectoderm

trophectoderm

 [trof-ek´to-derm]
the earliest trophoblast.

troph·ec·to·derm

(trof-ek'tō-derm),
Outermost layer of cells in the mammalian blastodermic vesicle, which will make contact with the endometrium and take part in establishing the embryo's means of receiving nutrition; the cell layer from which the trophoblast differentiates.

Our previous study demonstrated that aggregating porcine IVF embryos increased the in vitro development rate and total cell numbers, with a proportional increase in both ICM and trophectoderm (TE) cells and expression of mRNAs related to embryo quality (Lee et al.
The trophectoderm cells were lysed, and genomic DNA and negative control were amplified using the SurePlex DNA Amplification System (BlueGnome, UK) according to the manufacturer's instructions.
It looks like you can do pretty good trophectoderm biopsy on a vitrified blastocyst, so you can place only chromosomally normal embryos.
This permits the establishment of apico-basal polarity and thereby the 1st fate specification of the blastomeres: trophectoderm derives from blastomeres with a large apical membrane at the cell-medium interface; whereas blastomeres composing the inner cell mass descend from cells with comparably larger basal cell-cell interfaces.
non-selection trial, once embryos reach the blastocyst stage of development, each embryo will undergo trophectoderm biopsy and then cryopreservation.
The first baby was born alive after trophectoderm biopsy and preimplantation genetic testing of human blastocysts for beta Thalassaemia (104).
Representative slides demonstrated considerable integration of the Y chromosome throughout the inner cell mass and the trophectoderm (the tissue layer that forms the wall of the early embryo) of the 5-day-old recipient embryos and throughout the completely hatched 6-day-old recipient embryos.
It is believed that embryos must first differentiate into distinct embryonic regions, the ICM and the trophectoderm (TE), before apoptosis is engaged.
