Special Issue Information

Dear Colleagues,

Islet cells in the pancreas are endocrine organs that secrete insulin, which is important for blood sugar control. When islet cells are destroyed by viruses, immune disease or surgery, they cannot produce insulin, leading to severe insulin-dependent diabetes. Metabolic disorders can cause type 2 diabetes due to the loss of balance between diet and exercise. If type 2 diabetes leads to a chronic disability, patients will eventually need treatment with insulin injections outside the body, such as treatment for type 1 or other type of insulin dependent diabetes. Islet transplantation is the most fundamental clinical treatment for diabetes. However, the quality of islet cells required for transplantation is always an important issue. In order to solve this problem, in-depth research is needed on the method to isolate islet cells in good condition, with high yield from the whole pancreas of a cadaver or partial pancreas of pancreatic surgery patients. In addition, the method of freezing and storage of isolated islet cells and thawing them without functional damage after long-term storage will have high value for clinical application. In addition, research on stem cell-based therapy using autologous-induced pluripotent stem cells-derived insulin-producing cells to treat diabetes is being actively conducted by many researchers. This range of studies are of great help in islet cell-based diabetes treatment research and clinical development, so continuous and active research should be conducted.

Isolating a large quantity of high-quality human islets is a prerequisite for diabetes research. Human islets are typically isolated from the pancreases of brain-dead donors, making research difficult due to low availability. Pancreas tissue discarded after surgical resection may be a good alternative source of islet cells. To test this hypothesis, we isolated islets from discarded surgical specimens and evaluated the islet yield and quality as well as islet cell preparations. Eighty-two segmental pancreases were processed using the Ricordi automated method, and islet yield and quality were investigated. The mean age of patients was 54.6, and the cohort included 32 diabetes patients. After purification, partially resected pancreases yielded an average of 59,593 ± 56,651 islet equivalents (IEQs) and 2546 IEQ/g of digested pancreas, with 71.5 ± 21% purity. Multivariate analysis revealed that diabetes (p = 0.0046) and the lobe used (p = 0.0156) significantly altered islet yield. Islets transplanted into diabetic mice displayed good viability and in vitro glucose responses, DNA/RNA quality, mitochondrial function, and glucose control, even though these results were dependent on islet quality. Isolated cells also maintained high viability and function even after cryopreservation. Our findings indicate that pancreatic tissue discarded after surgery can be a valuable source of islets for diabetes research. Full article
