Indian Scientists Develop Placenta-on-Chip Platform for Pregnancy Research

By Published

Indian researchers from IIT Bombay and the Indian Council of Medical Research's National Institute for Research in Reproductive and Child Health (NIRRCH), Mumbai, have developed an innovative placenta-on-chip microfluidic device that mimics key placental functions. This technology aims to replicate nutrient and oxygen transfer between mother and fetus and the removal of waste products, thereby facilitating advanced pregnancy research, pharmaceutical drug testing, and reducing the dependence on animal models. Their device is fabricated using photolithography and soft lithography techniques and supports the study of pregnancy-related conditions such as preeclampsia and gestational diabetes. The project is supported by the Science, Engineering, and Research Board (SERB) under the IMPRINT II program, with patent filing underway.

Key Facts

  • The placenta is a temporary organ developing during pregnancy that ensures transfer of oxygen and nutrients from the mother to the fetus and removes waste from fetal blood.
  • Indian researchers from IIT Bombay and ICMR-NIRRCH, Mumbai, have created a placenta-on-chip device using microfluidic technology to replicate the physiological functions of the human placenta in vitro.
  • The device uses photolithography and soft lithography fabrication methods common in microengineering.
  • The placenta-on-chip platform aims to serve as an effective model for pregnancy research, drug testing, and to reduce reliance on animal models.
  • The models are especially designed to study pregnancy complications such as preeclampsia (a disorder characterized by high blood pressure and organ complications during pregnancy) and gestational diabetes (diabetes first diagnosed during pregnancy).
  • The project received financial support from SERB's IMPRINT II scheme and is in the process of patent filing.

Background & Context

Placenta plays a critical role in fetal development, forming a gatekeeper that controls nutrient and oxygen transfer while blocking harmful substances. Traditionally, pregnancy research has relied heavily on animal models that do not perfectly recapitulate human placental physiology. Advances in organ-on-chip microfluidic technology enable creating controlled laboratory platforms that mimic human organ functions closely. The placenta-on-chip thus represents a significant advancement in in vitro modeling of human pregnancies, providing better insight into placental function and associated disorders.

Why This Matters for Exams / Exam Relevance

This development highlights India's growing expertise in biomedical engineering and reproductive health research. Questions about institutions such as IIT Bombay and ICMR-NIRRCH, technologies like microfluidics and organ-on-chip systems, as well as pregnancy disorders like preeclampsia and gestational diabetes, align with current competitive exams themes in science and technology. Understanding such innovations reflects applied knowledge in biotechnology and healthcare relevant to national scientific progress.
