Trophoblasts, collected from the mother during a blood draw, can determine fetal genetic abnormalities currently diagnosed through amniocentesis or chorionic villi sampling.

The authors of a new study find no evidence for bacteria in the placenta, but others in the field question their interpretation of the data.

He established the San Diego Zoo’s cryopreserved Frozen Zoo.

Complications during pregnancy may act via the placenta to magnify the effects of genetic risk factors.

A small, placenta-produced peptide fixes the pregnancy-related condition in mice. 

Placentas from mice with genetically distinct immune systems, stained to highlight differences in three proteins, representing the nucleus (blue), blood vessels (red), and trophoblasts (green)

The lungs of extremely premature lambs supported in a closed, sterile environment that enables fluid-based gas exchange grow and develop normally, researchers report.

An endogenous retrovirus that supports placenta formation in females also helps male mice build muscle, according to a study.

Placental macrophages called Hofbauer cells are particularly vulnerable to infection by the virus, a study shows.
