Scientists advanced the of reproducing the body's by using 3D printing. Scientists could make organs by using bio-printing. Scientists could create of thin , like those used in our to let flow. These are called vascular networks. A bio-engineer said one to create tissue replacements has been an to print complex networks that can supply to tissue.
Another wrote about the of recreating vascular networks. She said: "Tissue has struggled with this for a ." She said: "If we can print tissues that look and now even breathe like the tissues in our bodies, will they also then behave more like tissues?" She said bio-printing could become a therapy. Scientists hope this method will help millions waiting for organ .
