Dissecting the First Transcriptional Divergence During Human Embryonic Development [PDF]

open access: yes, 2011
International audienceThe trophoblast cell lineage is specified early at the blastocyst stage, leading to the emergence of the trophectoderm and the pluripotent cells of the inner cell mass.

Perceptions of trophectoderm as a sentinel for embryo selection [PDF]

open access: yesJournal of Assisted Reproduction and Genetics, 2014
The archives of mammalian embryology are punctuated by landmark studies covering a rich tradition of technological bravado that spans 75 years. The most primordial perceptions of preimplantation embryo morphology were recorded at the Carnegie Institute for Embryology in Baltimore by the likes of Corner, Streeter, Hauser, Hartmann and others in the ...

Effect of Different Volume of Microdrop Culture on B6D2F1 Mice Oogenesis

open access: yesJournal of Animal Reproduction and Biotechnology, 2016
This study was conducted to evaluate the effects of different volume (100 μl vs. 2 ml) of microdrop culture on B6D2F1 mice oogenesis. In the present study, B6D2F1/CrljOri F1 mice were utilized in order to maximize oogenesis.

Implementation of Noninvasive Preimplantation Genetic Testing for Aneuploidy with Spent Blastocyst Medium into Clinical and Laboratory Practice: The First Successful Experience in Taiwan

open access: yesFertility & Reproduction, 2023
Noninvasive preimplantation genetic testing for aneuploidy (niPGT-A) using cell-free DNA (cfDNA) present in the spent blastocyst medium (SBM) of human blastocysts has emerged as an alternative for classical preimplantation genetic testing for aneuploidy (

Trophectoderm growth and bilateral symmetry of the blastocyst in the mouse [PDF]

open access: yesHuman Reproduction, 2002
The present study was undertaken to ascertain whether the polarized flow of cells from polar to mural trophectoderm is related to the axis of bilateral symmetry of the blastocyst in the mouse, and whether trophectoderm cells can initiate new cycles once they have left the polar region.Two different approaches were used to investigate the relationship ...

The Landscape and Regulation of Histone Crotonylation in Mammalian Gametes and Early Embryos

open access: yesAdvanced Science, EarlyView.
Histone crotonylation undergoes a genome‐wide transition from broad domains to canonical narrow peaks during minor zygotic genome activation (ZGA). This remodeling is required for proper major ZGA and blastocyst formation. Disruption of this transition by transcriptional inhibition, metabolic perturbation, or HDAC1 dysfunction impairs embryonic ...

The nuclear lamina couples mechanical forces to cell fate in the preimplantation embryo via actin organization

open access: yesNature Communications, 2023
During preimplantation development, contractile forces generated at the apical cortex segregate cells into inner and outer positions of the embryo, establishing the inner cell mass (ICM) and trophectoderm.

The effect of leukaemia inhibitory factor (LIF) on bovine embryo development in vitro : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in Animal Science at Massey University [PDF]

open access: yes, 1995
The aim of the study was to investigate the effect of Leukaemia Inhibitory Factor (LIF) either during in vitro maturation (IVM) or in vitro culture (IVC) on bovine embryo development. Three main experiments were conducted using oocytes aspirated from 2-8
