A protein found throughout the body plays a big role in immune system modulation in pregnancy and affects placental health, a study finds.

Measuring the placenta can determine the cause of previously unexplained miscarriages and stillbirths, say researchers.

Genetic conflict may play a role in pregnancy complications, such as preeclampsia and gestational diabetes, as well as developmental disorders.

Bits of viral genes incorporated into human DNA have been linked to cancer, ALS and schizophrenia. But many of these genes may not be harmful, and could even protect against infectious disease.

Researchers are developing a new way to monitor the placenta during pregnancy with optical measurements and ultrasound.

Direct transmission of BPA via the placenta can harm fetal brain development, researchers report. The new study explores mRNA's role.

Direct transmission of BPA from a mother to her developing child via the placenta can harm fetal brain development. A new study explores mRNA's role.

Stem cells from healthy placentas could one day help reduce brain injury in growth-restricted infants, babies who fail to grow normally in the womb.

A new study finds that placentas of male and female fetuses respond very differently when a mother is infected with SARS-CoV-2 during pregnancy.

An unexpected discovery could provide stem cells for the creation of placenta tissue. Until now, that hasn't been possible.
