Pancreatic islet analysis. A Representative hematoxylin–eosin (HE) staining for morphological evaluation of pancreatic islets at 14–15 and 18–20 weeks of age. B Pancreatic islet area analysis across experimental groups. (* p < 0.05). C Spearman correlation between islets’ area (µm2) and body weight (g). D Representative images for insulin immunohistochemical analysis. E Quantification of insulin-positive cells per pancreatic islets across groups. (p < 0.05; * vs. BTBRob/ob; # vs. SGLT2i; & vs. SGLT2i + CR; $ vs. SGLT2i + CR + BM-MSCs; continuous line indicated difference between time points). Scale bars represent 100 μm in A and D. Error bars represent mean ± SEM; n = 6 animals
