With this network of thin vessels, which is very hard to reproduce with a 3D printer, scientists bathed the structure in human cells that can grow around it since they would be nourished by it. As a result, the tissue will grow from this. The goal is to replace damaged tissue using leaves, this has not been successfully done yet, but scientists have made improvements in this area.
