How a Centuries-Old Sculpting Method Is Helping 3D Print Organs With Blood Vessels
Blood vessels are the lifeline of any organ. The dense web of channels, spread across tissues like a spider web, allow oxygen and nutrients to reach the deepest cores of our hearts, brains, and lungs. Without a viable blood supply, tissues rot from the inside. For any attempt at 3D printing viable organs, scientists have to tackle the problem of embedding millions of delicate blood vessels throughout their creation.
