The paper describes how clusters of specialised cells responsible for the production of insulin and glucagon in the pancreas have successfully been 3D printed into a scaffold.

Islet cells, also called Islets of Langerhans, are clusters of pancreatic cells that sense blood sugar levels and release insulin to maintain normal levels.

In their study, the group of researchers sought to increase the success of islet transplantation by creating bio-engineered scaffolds to help deliver the transplanted islet cells into patients, ensuring the cells are protected and fully functioning when placed at the donor site.
