A hexa-species transcriptome atlas of mammalian embryogenesis delineates metabolic regulation across three different implantation modes

open access: yesNature Communications, 2022
Mammalian embryogenesis relies on glycolysis and oxidative phosphorylation, but understanding of the dynamics of metabolic regulation in the postimplantation embryo in vivo remains elusive.

Pre-implantation mouse embryos cultured In vitro under different oxygen concentrations show altered ultrastructures [PDF]

open access: yes, 2020
Assisted Reproductive Technologies routinely utilize different culture media and oxygen (O2) concentrations to culture human embryos. Overall, embryos cultured under physiological O2 tension (5%) have improved development compared to embryos cultured ...

Embryo culture in presence of oviductal fluid induces DNA methylation changes in bovine blastocysts [PDF]

open access: yes, 2017
During the transit through the oviduct, the early embryo initiates an extensive DNA methylation reprogramming of its genome. Given that these epigenetic modifications are susceptible to environmental factors, components present in the oviductal milieu ...

Biosynthesis and expression of zona pellucida glycoproteins in mammals [PDF]

open access: yes, 2001
The zona pellucida (ZP) is an extracellular matrix surrounding the oocyte and the early embryo that exerts several important functions during fertilization and early embryonic development.

Cellular aspect ratio and cell division mechanics underlie the patterning of cell progeny in diverse mammalian epithelia. [PDF]

open access: yes, 2018
Cell division is essential to expand, shape, and replenish epithelia. In the adult small intestine, cells from a common progenitor intermix with other lineages, whereas cell progeny in many other epithelia form contiguous patches.

Haemogenic endocardium contributes to transient definitive haematopoiesis. [PDF]

open access: yes, 2013
Haematopoietic cells arise from spatiotemporally restricted domains in the developing embryo. Although studies of non-mammalian animal and in vitro embryonic stem cell models suggest a close relationship among cardiac, endocardial and haematopoietic ...

Molecular recording of mammalian embryogenesis. [PDF]

open access: yes, 2019
Ontogeny describes the emergence of complex multicellular organisms from single totipotent cells. This field is particularly challenging in mammals, owing to the indeterminate relationship between self-renewal and differentiation, variation in progenitor

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 ...

The occipital lateral plate mesoderm is a novel source for vertebrate neck musculature [PDF]

open access: yes, 2010
In vertebrates, body musculature originates from somites, whereas head muscles originate from the cranial mesoderm. Neck muscles are located in the transition between these regions.

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.
