Molecular and cellular mechanisms underlying the evolution of form and function in the amniote jaw. [PDF]

open access: yes, 2019
The amniote jaw complex is a remarkable amalgamation of derivatives from distinct embryonic cell lineages. During development, the cells in these lineages experience concerted movements, migrations, and signaling interactions that take them from their ...

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.

Editing DNA Methylation in Mammalian Embryos [PDF]

open access: yesInternational Journal of Molecular Sciences, 2020
DNA methylation in mammals is essential for numerous biological functions, such as ensuring chromosomal stability, genomic imprinting, and X-chromosome inactivation through transcriptional regulation. Gene knockout of DNA methyltransferases and demethylation enzymes has made significant contributions to analyzing the functions of DNA methylation in ...

Modeling mammalian gastrulation with embryonic stem cells

open access: yes, 2017
Understanding cell fate patterning and morphogenesis in the mammalian embryo remains a formidable challenge. Recently, in vivo models based on embryonic stem cells (ESCs) have emerged as complementary methods to quantitatively dissect the physical and ...

Synthesis of spectrin in avian erythroid cells: association of nascent polypeptide chains with the cytoskeleton [PDF]

open access: yes, 1983
The site of synthesis of spectrin was investigated in erythroid cells from 10-day chicken embryos. After various periods of [35S]methionine incorporation the cells were lysed in a Triton X-100 (TX-100)-containing buffer and were separated into a TX-100 ...

NaNog: A pluripotency homeobox (master) molecule. [PDF]

open access: yes, 2015
One of the most intriguing aspects of cell biology is the state of pluripotency, where the cell is capable of self-renewal for as many times as deemed necessary , then at a specified time can differentiate into any type of cell. This fundamental process

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.
