It’s an early step toward one day building new lungs: Yale University researchers took apart and regrew a rat’s lung, and then transplanted it and watched it breathe.
The lung stayed in place only for an hour or two, as the scientists measured it exchanging oxygen and carbon dioxide much like a regular lung _ but also spotted some problems that will take more research to fix.
Still, the work is a step in the science fiction-sounding hunt for ways to regenerate damaged lungs _ although lead researcher Dr. Laura Niklason cautions that it may be 20 or 25 years before a build-a-new-organ approach is ready for people.
The work was reported online Thursday in the journal Science.
