Fig. 5: Immunohistochemical analysis of the grafts in the subcutaneous space.

a Immunofluorescent stainings of insulin/glucagon, insulin/somatostatin, and insulin/CD31 within the group of 500 or 1000 islets with 40,000 MVF on day 105 after subcutaneous transplantation. Scale bar: 100 µm. b Quantitative analysis of islet cells (mean of all sections per graft) within the group of 500 (n = 5) or 1000 (n = 3) islets with 40,000 MVF. Mean ± SEM. c Quantitative analysis of CD31-positive cells (% of all islet cells) within the group of 500 (n = 5) or 1000 (n = 3) islets with 40,000 MVF. Mean ± SEM.
