Organs-on-chips reveal breathing’s critical role in lung cancer development

One of the biggest challenges facing cancer researchers — and lots of other medical researchers, in fact — is that experimental models cannot perfectly replicate human diseases in the laboratory.

That’s why human Organs-on-Chips, small devices that mimic human organ environments in an affordable and lifelike manner, have quickly been taken up into use by scientists in academic and industry labs and are being tested by the U.S. Food and Drug Administration.

Now, the chips have helped discover an important link between breathing mechanics and lung cancer behavior.
