The new device could help researchers see how different types of tissue respond to drugs without using lab animals.

Back story: Current organ-on-a chip systems place different kinds of human cells into a device andthen push fluid through them to mimic blood flow. That lets researchers see how, say, lung cells respond to different conditions.

What’s new: MIT engineers have now built a more complex version, which combines cells from 10 different organs—liver, lung, gut, endometrium, brain, heart, pancreas, kidney, skin, and skeletal muscle. That allows tests to see how different model organs react and interact with each other when exposed to different chemicals in the fluid.
