Why in News

Placenta-on-a-Chip is in the news after Indian researchers developed a laboratory-grown human placenta model to study how drugs, nutrients and harmful substances move from a mother to a developing fetus. The innovation provides a safer and more reliable alternative to animal models for pregnancy research.

What is Placenta-on-a-Chip?

Placenta-on-a-Chip is a microfluidic ‘organ-on-a-chip’ device that recreates the human placental barrier using living human cells. It mimics the interaction between maternal and fetal blood circulation, allowing scientists to observe biological transport under controlled laboratory conditions.

How Does It Work?

• The chip contains separate maternal and fetal chambers.
• Human placental cells form a functional barrier between the chambers.
• Researchers introduce medicines, nutrients or other substances into the maternal side.
• The movement of these substances across the placental barrier is monitored in real time.

Why is this Innovation Important?

• Improves understanding of drug safety during pregnancy.
• Helps study nutrient transport from mother to fetus.
• Evaluates the effects of pollutants, viruses and toxins.
• Reduces dependence on animal experimentation.
• Supports precision medicine and safer maternal healthcare.

What is Organ-on-a-Chip Technology?

Organ-on-a-chip technology uses miniature microfluidic devices lined with living human cells to simulate the structure and function of human organs. Similar models have been developed for the lung, liver, heart, kidney and brain, enabling more realistic biomedical research.

UPSC Significance

• Demonstrates the convergence of biotechnology, tissue engineering and microfluidics.
• Highlights India’s growing capabilities in biomedical innovation.
