Biophysical and chemical properties: (a) The gross appearance of a natural pancreas and a decellularized pancreas. H&E staining showed that there were no pathological signs of an immune rejection response in the transplanted acellular scaffold. SEM and TEM results showed that micro-vascular structures were retained after decellularization. b ELISA results suggested that most of the growth factors were preserved in decellularized pancreases. c MTT tests showed that the acellular scaffold is non-toxic to cells and suitable for co-cultured cells
