- Gastric fundus submucosa as a site for islets transplantation: An experimental study(2018) MESQUITA, Gustavo Heluani Antunes de; JARDIM, Yuri Justi; IUAMOTO, Leandro Ryuchi; SUGUITA, Fabio Yuji; ESSU, Felipe Futema; OLIVEIRA, Lucas Torres; MEYER, Alberto; CRESCENZI, Alessandra; ROCHA-SANTOS, Vinicius; GALVAO, Flavio H. F.; ANDRAUS, Wellington; CHAIB, Eleazar; D'ALBUQUERQUE, Luiz Augusto CarneiroBackground: Islets of Langerhans transplantation is a promising alternative for glycemic control in patients with type 1 diabetes. The graft site is a factor that has large impact on the functioning of this transplant, and the stomach appears to be a promising location. Our objective is to describe a new experimental model for the grafting of Islets of Langerhans in rat stomachs. Methodology: Islets of Langerhans were extracted from 45 isogenic male rats of the Lewis lineage and transplanted into 9 isogenic rats of the Wistar lineage; 5 in the gastric body submucosa, and 4 in the gastric fundus submucosa. Normoglycemia was defined as two successive measurements of < 250 mg/dL. No immunosuppression was used. The two groups glycemia control improvement were compared with t-student test. Results: The results obtained following the transplantation of the islets in 9 rats showed between 995 and 2310 islets transplanted (mean of 1367). The rats from the gastric submucosa group had a better glycemic level improvement, with a confidence equal to 83.94%. Conclusion: Islets graft into the gastric fundus submucosa is a viable model with potential for adequate glycemic control. This model gives potential for new perspectives and future studies in this area.
