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 ...

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 placenta has long been thought to produce serotonin during pregnancy. But in a new study, Yale researchers shatter the deep-rooted hypothesis—and show that the placenta doesn't produce serotonin ...

KANSAS CITY, MO—June 7, 2023—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 ...

Researchers have developed a cell culture test to detect substances that are directly or indirectly harmful to embryos. Based on an existing test used for developing new drugs and chemicals, the ...

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 ...

One often thinks that the early embryo is fragile and needs support. However, at the earliest stages of development, it has the power to feed the future placenta and instructs the uterus so that it ...

In April, researchers in China reported that they had initiated pregnancies in monkeys through a procedure seemingly much like in vitro fertilization (IVF), in which embryos created in a dish were ...

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 ...
