Developmental plasticity, cell fate specification and morphogenesis in the early mouse embryo [PDF]

open access: yes, 2014
A critical point in mammalian development is when the early embryo implants into its mother's uterus. This event has historically been difficult to study due to the fact that it occurs within the maternal tissue and therefore is hidden from view. In this

Heterogeneous X inactivation in trophoblastic cells of human full-term female placentas [PDF]

open access: yes, 1999
In female mammalian cells, one of the two X chromosomes is inactivated to compensate for gene-dose effects, which would be otherwise doubled compared with that in male cells.

The genome-defence gene Tex19.1 suppresses LINE-1 retrotransposons in the placenta and prevents intra-uterine growth retardation in mice [PDF]

open access: yes, 2013
DNA methylation plays an important role in suppressing retrotransposon activity in mammalian genomes, yet there are stages of mammalian development where global hypomethylation puts the genome at risk of retrotransposition-mediated genetic instability ...

Bmi1 facilitates primitive endoderm formation by stabilizing Gata6 during early mouse development [PDF]

open access: yes, 2012
International audienceThe transcription factors Nanog and Gata6 are critical to specify the epiblast versus primitive endoderm (PrE) lineages. However, little is known about the mechanisms that regulate the protein stability and activity of these factors

Pre-implantation maternal uterine effects on embryo growth and development : an investigation using models of maternal constraint in sheep : a thesis presented in fulfilment of the requirements for the degree of Doctor of Philosophy in Animal Science, Massey University, Turitea, Palmerston North, New Zealand [PDF]

open access: yes, 2017
Listed in 2017 Dean's List of Exceptional ThesesPrenatal development and growth are critical to survival of the fetus and neonate. Recent evidence suggests that a critical period for determining growth is the pre-implantation period of pregnancy during

Distinct mechanisms regulate Cdx2 expression in the blastocyst and in trophoblast stem cells [PDF]

open access: yes, 2016
The first intercellular differences during mammalian embryogenesis arise in the blastocyst, producing the inner cell mass and the trophectoderm. The trophectoderm is the first extraembryonic tissue and does not contribute to the embryo proper, its ...

Current status of in vitro differentiation of stem cells into gametes [PDF]

open access: yes, 2015
From an evolutionary point of view, the gametes are the cells in the body that matter the most as they are the ones who transmit their genes to the next generation ensuring continuation of the species. Being able to generate mature oocytes in vitro is of
