Talk about what we can do in the future.

The Wake Forest scientists, which included two different teams based in Winston-Salem, won the competition by 3D printing lab-grown human liver cells and placing them inside a specially-designed chamber that mimicked the human circulation system. The chamber was able to keep the cells alive for an entire month.

"I cannot overstate what an impressive accomplishment this is. When NASA started this challenge in 2016, we weren't sure there would be a winner," Reuter said in a statement. "It will be exceptional to hear about the first artificial organ transplant one day and think this novel NASA challenge might have played a small role in making it happen."

"But we were way too early, and the technology didn't support that goal," he said."The real problem was that you could not scale the tissues up above 20 cells thick. The tissues would begin to die because of a lack of blood flow." Still, the Wake Forest models represent incremental progress. Eventually, scientists will likely be able to create entire lab-grown organs, Willson said, but not at the moment.
