Using human lung organoids and patient samples, scientists found that during SARS-CoV-2 infection, lung immune cells halt cell growth and drive tissue damage.

To better understand respiratory diseases and develop new drugs faster, investigators designed a 3D "lung-on-a-chip" model of the distal lung and alveolar structures, the tiny air sacs that take ...

The other has built a microfluidic chip that mimics lung function, resulting in a biologically relevant model for testing medicines for lung disorders or conducting toxicity screens for nanoparticles.

Red blood cells carry oxygen from the lungs to every other organ, and blood-forming stem cells must make about 200 billion new red blood cells each day to keep the oxygen flowing. For many years, ...
