Dr. Atala on 3D tissue printing

Here’s a recent article by tissue engineering pioneer Dr. Anthony Atala. He makes a great point that printing tissue is beneficial not just so doctors can replace parts, but also so that drugs can be put through better testing.

He writes: “[I]n collaboration with five other institutions, we are working to print miniature hearts, lungs, blood vessels and livers onto “chips” that will be connected with a blood substitute. Called a “body on a chip,” the system has the potential to speed up the development of new drugs because it could potentially replace testing in animals, which can be slow, expensive and not always accurate.”
