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 ...

The placenta, critical for healthy embryo development, is a multi- purpose organ with a precise lifespan—the length of a pregnancy. New research from the Stowers Institute for Medical Research ...

A gene that turns on very early in embryonic development could be key to the formation of the placenta, which provides the developing fetus with what it needs to thrive during gestation. The placenta ...

Embryonic development, also known as embryogenesis, is a cornerstone in understanding the origins of life. But studying this marvel of intricate and layered biological processes in people faces ...

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 ...

Researchers have studied placental genes to explore how Assisted Reproductive Technology (ART) affects a child's development. Differences showed up between pregnancies from frozen and fresh embryo ...

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.

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 ...

A research team headed by Prof. Jacob Hanna at the Weizmann Institute of Science has created complete models of human embryos from stem cells cultured in the lab—and managed to grow them outside the ...

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 ...
