The system allows scientists to study how substances pass between mother and fetus without invasive testing. Researchers say the technology could support safer drug development and improve medical guidance during pregnancy.

The artificial placenta replicates key biological functions of the human placenta in a laboratory setting. According to the report, scientists hope the model will reduce uncertainty surrounding medication use during pregnancy, an area where clinical research has historically been limited. The technology could also help accelerate research into pregnancy-related health conditions and treatments.
