Scientists say they have advanced the possibility of being able to reproduce the body's via the use of 3D printing. Replacement organs could be created using a new for bio-printing organic tissue. This allows scientists to create networks of tubes and vessels, like those used in our body for the of blood and air. These are called networks. Bio-engineering professor Jordan Miller explained why the was so . He said: "One of the biggest roadblocks to generating functional tissue replacements has been our to print the complex [vascular networks] that can supply nutrients to populated tissues."

Professor Kelly Stevens of the University of Washington wrote about the scientists had in recreating a vascular network. She said: "Tissue has struggled with this for a ." She believes the new breakthrough will allow medical practices to change in the . She asked: "If we can print tissues that look and now even breathe like the healthy tissues in our bodies, will they also then behave more like those tissues?" Professor Stevens said "This is an question, because how well a bio-printed tissue functions will affect how it will be as a therapy." Scientists hope this will help millions of people waiting for an organ .
