A 3D mechanical model of the early mammalian embryo [PDF]

open access: yes, 2009
The early development of the mammalian embryo leads to the formation of a structure composed by an outer layer of polarized cells surrounding an inner mass of nonpolarized cells.

Liver organoids: modelling complexity in homeostasis and disease

open access: yesFEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

HLA-G MOLECULES: FROM EMBRYO IMPLANTATION TO OOCYTE MATURATION [PDF]

open access: yes, 2009
Background Assisted reproduction technique (ART) pregnancy rates have not changed in recent years and an increased risk of twins, triplets or higher order pregnancies leads to a perinatal mortality and morbidity.

Translophagy—A potential link between autophagy impairment and translational errors

open access: yesFEBS Letters, EarlyView.
Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

In Vitro Host-Cell Susceptibility to Usutu Virus

open access: yesEmerging Infectious Diseases, 2005
We investigated the susceptibility to Usutu virus (Flavivirus) of 13 permanent cell lines, 3 primary cell cultures, and chicken embryos. Vero, PK-15, and goose embryo fibroblast cells developed cytopathic effects; however, viral multiplication was ...

Effects of mammalian sex hormones on in vitro organogenesis of common bean (Phaseolus vulgaris L.)

open access: yesScientific Reports, 2023
Beans are an important plant species and are one of the most consumed legumes in human nutrition, especially as a protein, vitamin, mineral, and fiber source.

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

open access: yesFEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

The chicken embryo and its micro environment during egg storage and early incubation [PDF]

open access: yes, 2008
When egg storage periods are prolonged (>7 days), hatchability and chick quality declines. The reason for this decline has been investigated, but is still not completely understood.

Embryo splitting

open access: yesMiddle East Fertility Society Journal, 2010
Mammalian embryo splitting has successfully been established in farm animals. Embryo splitting is safely and efficiently used for assisted reproduction in several livestock species.
