How PFAS chemical exposure may harm the placenta and blood vessels in pregnancy

Per- and poly-fluoroalkyl substances (PFAS) in pregnancy vascular and placental dysfunction

NIH-funded research University of Wisconsin-Madison · NIH-11251954

This project looks at whether PFAS chemicals during pregnancy damage mothers' blood vessels and placentas and lead to babies growing too small.

What this research studies

If you are pregnant or planning pregnancy, this research is trying to understand whether common PFAS chemicals can cause problems that make babies too small. The team will use experiments in animals to see if PFAS raise maternal blood pressure and reduce placental size. They will study placental tissue outside the body to measure blood vessel function and nutrient transfer. Lab tests will examine molecular signals that control placental blood vessel growth and nutrient transport.

Who could benefit from this research

Good fit: People who are pregnant or planning pregnancy and who are concerned about or known to have higher PFAS exposure, or who have had fetal growth restriction, would be most relevant to this research.

Not a fit: People who are not pregnant or whose fetal growth problems are clearly due to genetic or non-environmental causes are unlikely to benefit directly from this grant's work.

Why it matters

Potential benefit: If successful, the work could identify how PFAS exposure causes fetal growth restriction and point to ways to prevent or reduce harm from these chemicals.

How similar studies have performed: Epidemiological studies have linked PFOS and other PFAS to poor fetal growth and pilot animal studies show vascular and placental effects, but the specific mechanisms remain unproven.
