Wake Forest team won a NASA award for 3D printing human liver tissue


Skinks think they are just too cool. Through our efforts, human beings still lack the physiological ability to regenerate lost limbs and damaged organs. Well, we won’t do this until at least this week.A pair of research teams from Wake Forest University Institute of Regenerative Medicine Has exceeded NASA’s long-term operation Vascular tissue challenge after 3D printed biologically viable human liver block.

These two teams are called Winston and WFIRM respectively. Each team managed to produce a large piece of meat in a centimeter square. Although using different methods, they can survive and can run for 30 days nominally. Yes, of course, even NASA admits that both teams rely on similar “3D printing technology to make gel-like molds or scaffolds, with a network of channels designed to maintain sufficient oxygen and nutrient levels to maintain the constructed tissue Survive,” they are different. About their printing design and materials.

“I can’t exaggerate what an impressive achievement this is. When NASA started this challenge in 2016, we were not sure whether there would be a winner,” NASA Deputy Director of Space Technology Jim Reuter said in a recent press statement Said in. “One day it will be very special to hear about the first artificial organ transplantation and think that this new challenge from NASA may have played a small role in achieving it.”

Winston was declared the winner, so not only did the team get $300,000 for further development of the technology, but the team could also send its experiment to the International Space Station for further testing-I mean, you have to make sure the next one The lab-printed liver has enough RAD resistance. The WFIRM team will receive $100,000 but will not conduct an orbital expedition to continue its research.

The medical procedures and products that may be produced through this research are likely to be revolutionary. Rather than relying on a network of volunteers, tomorrow’s organ transplant candidates may just print their replacement organs before the transplant operation, which actually eliminates their chance of rejection and basically guarantees a complete genetic organ match every time.

Lynn Harper, Challenge Administrator of NASA’s Ames Research Center, added: “The value of artificial tissue depends entirely on how well it mimics what happens in the body.” The requirements are precise and vary from organ to organ. This makes this task extremely complicated. “Rigid and complex. The research resulting from this NASA challenge represents a benchmark, a well-documented basis on which further developments can be made.”
