Improving pregnancy understanding with a “placenta on a chip”

Studying the placenta and the ways in which materials can move across the maternal-fetal barrier is important to prenatal research, but it can be difficult and time-consuming. However, new research is providing a way for these processes to be studied more easily: a “placenta on a chip”! Previously, cell and animal studies have been important […]
