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 ...

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 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 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 ...

Content warning: This interview includes discussion of miscarriage and pregnancy loss, and may be triggering for some listeners. The placenta is an incredible body part. It’s the only organ grown ...

We have all had one, and we owe our lives to it. It’s the first organ to develop and it simultaneously serves as the lungs, kidneys, immune system, and digestive tract, to name a few, in a fetus while ...

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 ...

With embryolike constructs built entirely from stem cells, researchers can revolutionize our understanding of development. But how close to an embryo is too close? In April, researchers in China ...
