Wake Forest teams won a NASA award for 3D printing of human liver tissues

Skinks think they’re just so cool. Through not a lack of effort on our part, humans also lack the physiological ability to regenerate lost limbs and damaged organs. Well, we didn’t do that until this week, at least. A couple of research teams from Wake Forest University Institute of Regenerative Medicine they overcame NASA’s long run Vascular Tissue Challenge yes 3D printing a feasible biological part of human liver.

The teams, nicknamed Winston and WFIRM, respectively, were each able to produce one square centimeter piece or piece capable of surviving and operating nominally for a period of 30 days, even if using divergent methodology. Yes, of course, even NASA admits that the two teams rely on similar 3D printing technologies to create images such as gels, or scaffolds, with a network of channels designed to maintain sufficient oxygen and nutrient levels. to keep the built tissues alive. on their designs and printing materials.

“I can’t exaggerate what an impressive success this is. When NASA started this challenge in 2016, we weren’t sure if there was a winner,” said Jim Reuter, NASA’s associate administrator for space technology. , in a recent press release. “It will be exceptional to hear about the first artificial organ transplant one day and to think that this new challenge from NASA could have played a small role in its reality.”

Winston was declared the winner so the team will receive not only $ 300,000 to promote the development of the technology, the team will receive to submit their experiment to the ISS for further testing – I mean, you have to make sure the next liver is printed in the laboratory is quite RAD resistant. The WFIRM team will receive $ 100,000, but no orbital shipments, to continue their search.

The medical procedures and products that could be born through this research could be revolutionary. Instead of relying on a network of volunteers, tomorrow’s organ transplant candidates may have just stamped their replacement organs prior to their transplant surgeries, virtually eliminating their chances of rejection and essentially guaranteeing a match of organs. ‘complete genetic organs each time.

“The value of an artificial tissue depends entirely on how much it mimics what’s happening in the body,” added Lynn Harper, challenge manager at NASA’s Ames Research Center. “The needs are precise and vary from organ to organ, making the task extremely demanding and complex. Research resulting from this challenge by NASA represents a benchmark, a well-documented foundation for building the next advance.”
