A gene that turns on very early in embryonic development could be key to the formation of the placenta, which provides the ...

GAINESVILLE, Fla. — Researchers studying embryonic stem cells have explored the first fork in the developmental road, getting a new look at what happens when fertilized eggs differentiate to build ...

The effect of genetic changes on the placenta has not been systematically studied to date. Of 103 gene mutations that lead to the death of a developing fetus in mice, 68% caused defects in the ...

I am not the first person who has considered composing poetry to the placenta. One writer begins: “Oh Lady Placenta! What a life you lived in magenta.” Another almost coos to the “constant companion, ...

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 is in essence the 'serotonin shield' that regulates how much serotonin is ultimately delivered to the embryo and fetus, not the source of serotonin," said Harvey Kliman, a research ...

While other animal embryos grow outside the mother, their embryonic cells can get right to work accepting assignments, such as head, tail or vital organ. By contrast, mammalian embryos must first ...

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 ...

The Cyclostomata is an ancient group of aquatic colonial suspension-feeders from the phylum Bryozoa. The fact that they have unique placentae has been discovered by researchers at St Petersburg ...

The role of the placenta in fetal development is being seriously under-appreciated according to scientists. A team studied 103 mutations linked to prenatal death in mice and showed that almost 70 ...
