Skinks think they’re just sooooo cool. Through no shortage of effort on our part, humans still lack the physiological capacity to regrow lost limbs and damaged organs. Well, we didn’t until this week, at least. A pair of research teams from Wake Forest University’s Institute for Regenerative Medicine have topped NASA’s long-running Vascular Tissue Challenge by 3D printing a biologically viable chunk of human liver.
The teams, respectively dubbed Winston and WFIRM, each managed to produce a centimeter-square hunk-o-meat capable of surviving and nominally operating for a span of 30 days, albeit using divergent methodologies. Yeah, granted, even NASA admits that both teams relied on similar “3D printing technologies to create gel-like molds, or scaffolds, with a network of channels designed to maintain sufficient oxygen and nutrient levels to keep the constructed tissues alive,” they differed on their printing designs and materials.Continue reading… “Wake Forest teams win a NASA prize for 3D printing human liver tissue”
