Scientists have grown healthy human placental cells in a laboratory using a new technique, providing a means to test the safety of drugs during pregnancy. The cells can survive and function like those in the womb, mimicking blood flow and nutrient exchange.
A recent study led by Professor Susan Fisher of the University of California at San Francisco found that low oxygen levels regulate cell proliferation in early pregnancy, controlling placental development. The team also discovered a process similar to cancerous growth occurs when cells invade healthy tissue under low-oxygen conditions.
Preeclampsia occurs when cytotrophoblasts fail to invade the uterine wall and mimic blood vessel cells, leading to high blood pressure and potential complications. Early detection through testing could save lives and prevent birth defects.
