Carnegie Mellon University College of Engineering/AFP / HO This undated image Courtesy of Carnegie Mellon University College of Engineering shows a functional heart valve which a team of US scientists have built out of collagen using a 3D bioprinter.The breakthrough they say could one day create entire organs. Their technique, which was described in the journal Science on August 1, 2019, replicates the body's own complex biological scaffolds that provide the structure and biochemical signaling organs need to function. "What we were able to show was you can actually 3D print a heart valve out of collagen, and they function," Adam Feinberg, one of the paper's co-authors told AFP
