20 yrs to go for humans - Lab-grown lungs successfully transplanted into pigs

[iolaire]

Good story about transplanting lab grown lungs into pigs.  At this point the transplants work but the lungs do not function.

But getting to humans will take some time:
“In my mind, we’re still probably 20 years away from a first in-man human-engineered lung,” said Laura Niklason, a professor of anesthesiology and biomedical engineering at Yale University who is working on bioengineered lungs as part of another team of researchers.

The 20 years sounds realistic to me.  Sometimes with the Kidney news the timeline sounds unrealistic to me.
