Re-biopsy and modified biopsy in mosaic human embryos with simple segmental chromosomal deletion [PDF]
Background There is a considerable proportion of false positive results when the result of preimplantation genetic testing for aneuploidy is chromosomal mosaicism.

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.

microRNA expression during trophectoderm specification. [PDF]
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
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.

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 ...

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 ...

Development of an Improved in vitro Model of Bovine Trophectoderm Differentiation
The mechanisms regulating early stages of placentation and trophectoderm differentiation in the ruminant conceptus remain poorly understood. Here we present a model of trophectoderm (TE) differentiation in vitro from outgrowths of individual in vitro ...

BackgroundElective single blastocyst transfer (eSBT) is considered to reduce the incidence of multiple pregnancy compared to double embryo transfer. Blastocyst selection is the key to achieving pregnancy.

During mammalian gastrulation, germ layers arise and are shaped into the body plan while extraembryonic layers sustain the embryo. Human embryonic stem cells, cultured with BMP4 on extracellular matrix micro-discs, reproducibly differentiate into ...
