Trophectoderm, Inner Cell Mass, and Expansion Status for Live Birth Prediction After Frozen Blastocyst Transfer: The Winner Is Trophectoderm [PDF]

open access: goldLife
Despite advancements in technologies such as time-lapse microscopy and artificial intelligence, the gold standard for embryo selection still relies on standard morphological assessment. Several studies have investigated the correlation between blastocyst

NuRD-dependent DNA methylation prevents ES cells from accessing a trophectoderm fate [PDF]

open access: goldBiology Open, 2012
Summary Embryonic Stem (ES) cells are able to give rise to the three germ layers of the embryo but are prevented from contributing to the trophoblast. The molecular nature of this barrier between embryonic and trophectodermal cell fates is not clear, but

Re-biopsy and modified biopsy in mosaic human embryos with simple segmental chromosomal deletion [PDF]

open access: yesReproductive Biology and Endocrinology
Background There is a considerable proportion of false positive results when the result of preimplantation genetic testing for aneuploidy is chromosomal mosaicism.

Revealing cell populations catching the early stages of human embryo development in naive pluripotent stem cell cultures

open access: yesStem Cell Reports, 2023
Summary: Naive human pluripotent stem cells (hPSCs) are defined as the in vitro counterpart of the human preimplantation embryo’s epiblast and are used as a model system to study developmental processes.

A Shorter Equilibration Period Improves Post-Warming Outcomes after Vitrification and in Straw Dilution of In Vitro-Produced Bovine Embryos

open access: yesBiology, 2021
This study was designed to the optimize vitrification and in-straw warming protocol of in vitro-produced bovine embryos by comparing two different equilibration periods, short equilibrium (SE: 3 min) and long equilibrium (LE: 12 min).

microRNA expression during trophectoderm specification. [PDF]

open access: yesPLoS ONE, 2009
Segregation of the trophectoderm from the inner cell mass of the embryo represents the first cell-fate decision of mammalian development. Transcription factors essential for specifying trophectoderm have been identified, but the role of microRNAs (miRNAs)

The Long Terminal Repeats of ERV6 Are Activated in Pre-Implantation Embryos of Cynomolgus Monkey

open access: yesCells, 2021
Precise gene regulation is critical during embryo development. Long terminal repeat elements (LTRs) of endogenous retroviruses (ERVs) are dynamically expressed in blastocysts of mammalian embryos.

Effect of blastocyst morphology on the incidence of monozygotic twinning pregnancy after single blastocyst transfer

open access: yesGynecological Endocrinology, 2023
Aims: To explore whether blastocyst morphology [blastocyst stage, inner cell mass (ICM), and trophectoderm (TE) grading] impacts the occurrence of monozygotic twinning (MZT) after single blastocyst transfer (SBT).Materials and methods: A single-center ...

Karyotype of the Blastocoel Fluid Derived by Laser-Assisted Hatching Demonstrates a Low Agreement With the Trophectoderm

open access: yesFrontiers in Physiology, 2022
ObjectiveThe aim of this study is to compare the amplification efficiency and the genomic profiles of blastocoel fluid (BF) derived by laser-assisted hatching and trophectoderm (TE) cells derived from the same blastocyst.MethodsFifty-four fresh ...
