Print the Organ that You Need

Imagine printing a picture on a piece of paper, and printing over it repeatedly such that the picture ‘grows’ out of the paper and into a three-dimensional structure. Researchers from University of California, San Diego and collaborators from Zhejiang University did that, but with biocompatible polymers instead of regular ink to form complex three-dimensional scaffolds. The researchers can then inject living cells into these scaffolds to create artificial organs.
