3D printed T1D treatment?

To achieve that high density, Perrier and his colleagues 3D printed islets from a “bioink” made of human pancreatic tissue and alginate, a type of carbohydrate derived from seaweed. Live insulin-producing cells were mixed into this material.

“We put this bioink with the [human] islet into a syringe, and we print a special motif [with it],” says Perrier. This porous grid is designed to allow new blood vessels to grow around and through the structure.

In the lab, this technique “works very well”, says Perrier, noting that about 90 per cent of the islets’ cells survived and functioned for up to three weeks. “The next challenge is really to validate this finding in vivo.” Perrier and his colleagues presented their research at the European Society for Organ Transplantation (ESOT) 2025 meeting in London on 29 June.
