Scientists Create Functional 3D-Printed Human Islets for Type 1 Diabetes Treatment
In a significant advancement for type 1 diabetes treatment, scientists have successfully created functional 3D-printed human islets. This breakthrough,presented at the European Society for Organ Transplantation Congress 2025,offers the potential to eliminate the need for insulin injections.
The team, led by Dr. Quentin Perrier, focused on replicating the pancreatic habitat to enhance the survival and function of transplanted cells. They used a specialized bioink that mimics the pancreas’ support structure, ensuring islets receive adequate oxygen and nutrients.
To protect the delicate human islets during printing, the researchers developed a gentler printing method. By carefully adjusting settings such as low pressure (30 kPa) and slow print speed (20 mm per minute), they minimized physical stress on the islets, preserving their natural shape. This addressed a major challenge in previous bioprinting attempts.
Laboratory tests revealed that over 90% of the bioprinted islets remained alive and healthy. Moreover, they exhibited an enhanced response to glucose, releasing more insulin when needed. By day 21, the islets demonstrated a stronger ability to sense and react to blood sugar levels, indicating their potential for effective function after implantation.The 3D-printed structures also maintained their integrity without clumping or breaking down.
The 3D-printed structures feature a porous design that enhances oxygen and nutrient flow to the embedded islets. this promotes cell health and vascularization, both crucial for long-term survival and function following transplantation.
“This is one of the first studies to use real human islets instead of animal cells in bioprinting, and the results are incredibly promising,” Dr. Perrier said. “It means we’re getting closer to creating an off-the-shelf treatment for diabetes that could one day eliminate the need for insulin injections.”
What’s next
The team is now conducting tests on animal models and exploring long-term storage options like cryopreservation to ensure widespread availability of the therapy. They are also adapting the method for choice sources of insulin-producing cells, including stem-cell-derived islets and xeno-islets (from pigs), to address donor shortages. The scientists are hopeful that clinical trials will confirm the effectiveness of this new bioprinting method, potentially transforming diabetes treatment and improving the quality of life for millions.
