Fig. 3From: Comparison of therapeutic effects of mesenchymal stem cells from umbilical cord and bone marrow in the treatment of type 1 diabetesEffects of BM-MSCs or UC-MSCs infusion on β-cell mass and insulin production. A Representative micrographs of insulin immunohistochemical staining showing β cells preserved in islets at 14 days post-transplantation. Scale bar, 100 μm. B The insulin-positive staining areas (%) in pancreatic islets were quantified using the Image-Pro Plus 6.0. Four slides per mouse (four mice per group) were analysed, and at least 20 islets from the pancreatic tissue of each mouse were evaluated. C Random serum insulin concentration (N = 4–5). Data are presented as mean ± SEM. *P < 0.05 versus the control groupBack to article page
