A Tale of Division and Polarization in the Mammalian Embryo [PDF]

open access: yesDevelopmental Cell, 2017
The first cell fate choice in mouse development is the segregation of the embryonic inner cell mass and the extra-embryonic trophectoderm. In this issue of Developmental Cell, Korotkevic and colleagues (2017) show that the interplay between cell polarization and cell-cell contact drives the segregation of these lineages, providing a framework for self ...

Complications Associated with Uterine Artery Embolisation for Fibroids

open access: yesObstetrics and Gynecology International, 2012
Uterine artery embolisation (UAE) is a relative newcomer to the mainstream treatment modalities available for fibroid-related problems. The efficacy of UAE is indisputable and has been shown to be comparable to hysterectomy in the short term in large ...

Protocadherin-1 is expressed in the notochord of mouse embryo but is dispensable for its formation

open access: yesBiochemistry and Biophysics Reports, 2021
Notochord is an embryonic midline structure that serves as mechanical support for axis elongation and the signaling center for the surrounding tissues.

Instructions for Assembling the Early Mammalian Embryo [PDF]

open access: yesDevelopmental Cell, 2018
The preimplantation mouse embryo is a simple self-contained system, making it an excellent model to discover how mammalian cells function in real time and in vivo. Work over the last decade has revealed some key morphogenetic mechanisms that drive early development, yielding rudimentary instructions for the generation of a mammalian embryo.

The p66(Shc) adaptor protein controls oxidative stress response in early bovine embryos. [PDF]

open access: yesPLoS ONE, 2014
The in vitro production of mammalian embryos suffers from high frequencies of developmental failure due to excessive levels of permanent embryo arrest and apoptosis caused by oxidative stress.

Asynchronous mouse embryo polarization leads to heterogeneity in cell fate specification

open access: yeseLife
The first lineage allocation in mouse and human embryos separates the inner cell mass (ICM) from the outer trophectoderm (TE). This symmetry-breaking event is executed through polarization of cells at the 8 cell stage and subsequent asymmetric divisions,

Epigenetic regulation in mammalian preimplantation embryo development

open access: yesReproductive Biology and Endocrinology, 2009
Preimplantation embryo development involves four stages: fertilization, cell cleavage, morula and blastocyst formation. During these stages, maternal and zygotic epigenetic factors play crucial roles.

Reorganization, specialization, and degradation of oocyte maternal components for early development

open access: yesReproductive Medicine and Biology, 2023
Background Oocyte components are maternally provided, solely determine oocyte quality, and coordinately determine embryo quality with zygotic gene expression.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.
