3D-Printed Organs and Tissues Pave the Way for a Medical Transformation
Key Points 3D bioprinting involves layering living cells onto scaffolds to create complex, functional tissues that resemble natural organs. Functional heart valves, skin grafts, and miniature organs, such as livers and kidneys, have been successfully created, yielding promising results in animal models. 3D bioprinting could also revolutionize drug discovery by enabling the creation of "organs-on-a-chip" for more accurate drug testing. Despite challenges, the promise of...
