In previous methods engineered functional tissues were seeded onto biodegradable structures, but difficulty in predicting when the structure would fully degrade and the risk of it interfering with necessary cell-to-cell connections highlighted the need for a new approach. Researchers at the University of Illinois at Chicago created a new 3D printing method using a form of ink made from stem cells, forming gel beads.
