Implantable blood vessels 3D printed from human cells

Researchers in Asia have reportedly 3D printed a biomimetic blood vessel - derived from human smooth muscle and endothelial cells - bringing 3D-printed vascular structures a step closer to clinical use. A modified, 'triple-coaxial' 3D printing technique has been reported successful in the printing of a biomimetic blood vessel. Using a bioink derived from smooth muscle from a human aorta and endothelial cells from an umbilical vein, the team has been able to produce a fully functional blood vessel with dual-layer architecture.Figure 1: Researchers in Asia used triple-coaxial cell printing technology to construct biomimetic tissue-engineered blood vessels that include an...
