This chip full of cells and fluids mimics the mechanical and
biochemical behaviors of a human lung. In the future it may
help scientists conduct more accurate drug screenings.
In the past few years scientists have been building organs on chips—microfluidic devices seeded with human cells and designed to function like miniatures of real-life lungs, hearts and kidneys. Scientists hope these mock organs will eventually help to understand and treat diseases, but first, they have to get these fake organs, well, sick. Researchers at Harvard recently reported some success: they have given their chip a lung condition.
