Scientists Create ‘Lung on a Chip’

Researchers at Harvard’s Wyss Institute have combined microfabrication techniques from the computer industry with modern tissue engineering techniques, human cells and a plain old vacuum pump to create a living, breathing human lung-on-a-chip. The device mimics the most active part of the lung, the boundary between the air sac and the bloodstream. Credit: Alyssa Kneller, Harvard Medical School
