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, ...

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 either an embryo or a ...

The first stages of placental development take place days before the embryo starts to form in human pregnancies. The finding highlights the importance of healthy placental development in pregnancy, ...

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 human placenta is an organ unlike any other. During the course of nine months it is formed by the embryo, sustains life and then is shed. "What that means," said Montserrat Anguera, an assistant ...

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 ...

A new study solidifies an important role for both TLK1 and TLK2 in genome stability. This work is also the first to report on the key role of the TLK2 gene in mouse embryo development. The placenta, a ...

An experimental study from researchers in the Perelman School of Medicine at the University of Pennsylvania links a specific procedure - embryo culture - that is part of the assisted reproduction ...

I didn't think much about placentas until I had one and part of it dislodged halfway through a 4-mile run. Happily it ended well some months later with a "small for gestational age" tiny baby and a ...

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 ...
