In mammals, signalling between the placenta and the embryo is essential for successful development. Here, a quantitative, time-resolved model describes the coordinated formation of the mouse embryo ...

A stem cell–derived human embryo model at a developmental stage equivalent to that of a day 14 embryo. The model has all the compartments that define this stage: the yolk sac (yellow) and the part ...

A new study led by Pr. Serge McGraw, researcher at CHU Sainte-Justine and professor at Université de Montréal, shows that the effects of alcohol exposure on an embryo prior to implantation in the ...

The discovery of a gene essential to early embryonic development sheds light on the preliminary stages of human placenta formation. A team led by scientists from the University of California San Diego ...

HONOLULU — The risk for placenta accreta is 3 times higher in pregnancies achieved with in vitro fertilization using frozen embryo transfer than in those using fresh embryos, according to a new study.

Researchers have used stem cells to develop new human embryolike structures that model the earliest stages of fetal development so realistically that they even secrete hormones that can turn a lab ...

(Nanowerk News) Cambridge scientists have created a stem cell-derived model of the human embryo in the lab by reprogramming human stem cells. The breakthrough could help research into genetic ...

Congenital heart defects are the most common form of human birth defect, but we still don't fully understand what causes them. Previous research had suggested that some heart defects could be ...

Cellular aggregates derived from human stem cells in previous studies could not be considered genuinely accurate human embryo models, because they lacked nearly all the defining hallmarks of a ...
