Indian researchers have unveiled a groundbreaking "placenta-on-chip" technology, a lab-grown model replicating crucial functions of the human placenta. This innovative platform, developed by ICMR-NIRWoH and IIT Bombay, promises to unravel mysteries surrounding pregnancy, aid in understanding complications like gestational diabetes, and evaluate drug safety, potentially reducing reliance on animal testing. The simple, scalable design aims for widespread adoption in research.
