Understanding the molecular control of placenta formation, the organ which enables fetal growth, is critical in diagnosing and treating related pregnancy complications. A group of scientists at the ...

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 ...

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 ...

Scientists have created a breakthrough polymer chip designed to mimic a human placenta and embryo to stop the 'unethical and cruel' drug testing on more than two million pregnant mice worldwide each ...

Drugs must be safe not just for the patients; in the case of pregnant patients, drugs must also be safe for the unborn children still in the womb. Therefore, at an early stage in the development of ...

Pioneering research led has provided new insight into formation of the human embryo. Pioneering research led by experts from the University of Exeter's Living Systems Institute has provided new ...

Alcohol exposure in very early pregnancy (before embryo implantation) can lead to long-term molecular changes detectable in the placenta, potentially providing a tool for early detection of prenatal ...

University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that ...

It turns out that a gene called LTR5Hs activates a gene that affects the growth of an embryo and the proliferation of stem ...

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.
