A team of bioengineers, funded in part by NIGMS, has devised a way to use 3D bioprinting technology to construct the small air sacs in the lungs and intricate blood vessels. When hooked up to a machine, the air sacs can “breathe,” and the blood flowing through the tiny blood vessels can take up oxygen, much like they would in an animal’s body. In the long term, this technology may allow the production of replacement organs for patients who need them.
