Clinical Study on the Safety and Efficacy of Immunophenotyped Pancreatic Endocrine Organoid Bank in Treating Patients With T3c Diabetes

Islet cells are isolated from resected pancreatic tissue obtained from patients undergoing surgery, followed by ex vivo expansion and culture. Subsequent procedures include HLA typing, functional assessment of organoid-like structures, and biobanking. After matching for HLA, the cells are administered into patients with type 3c diabetes mellitus (T3cDM) via ultrasound-guided percutaneous transhepatic portal vein catheterization. A 52-week follow-up is conducted to evaluate the safety of the cell therapy and its clinical efficacy in glycemic control.
