Scientists have advanced the of reproducing the body's organs via the of 3D printing. Scientists could replace by using a new bio-printing . This allows scientists to create networks of thin , like those used in our body for the of blood and air. These are called vascular networks. A bio-engineering professor explained why the was important. He said: "One of the biggest roadblocks to generating tissue replacements has been our inability to print the [vascular networks] that can supply nutrients to populated tissues."

Another wrote about the scientists had in recreating vascular networks. She said: "Tissue engineering has struggled with this for a ." She thinks the breakthrough will allow medicine to change in the . She asked: "If we can print tissues that look and now even breathe more like the tissues in our bodies, will they also then functionally behave like those tissues?" She added that how well bio-printed tissue functions will affect successful it will be as a . Scientists hope this will help millions waiting for organ .
