Figure 7: Histology analysis. Representative images of transplanted pancreatic islets in scaffolds stained with haematoxylin/eosin (H&E) and immunohistochemically with primary antibodies anti-insulin and CD31. Viable islets containing insulin positive cells were present in the scaffolds (H&E) in all groups A-D. Endothelial structures (CD31) were found in close proximity to the islets. Scale bars correspond to 100 µm.
