Figure 4

Liver tissue treated with non-thermal irreversible electroporation (NTIRE) and injected with PBS served as the control. Seven days after treatment with NTIRE and injection of PBS, immunohistochemical staining was performed on the controls using insulin and glucagon antibodies (University of Texas at Houston, USA). In the control slides, no cells were stained with insulin or glucagon antibodies, shown in (A) and (B), respectively. The higher magnification panel 4C shows normal hepatocytes with no evidence of scar tissue.

Figure 5

Liver tissue treated with non-thermal irreversible electroporation (NTIRE) and injected with 200 rat donor pancreatic islets. Seven days later, immunohistochemical staining was performed with anti-insulin and anti-glucagon antibodies (University of Texas at Houston, USA). In the pancreatic islets injected tissue, insulin-stained cell clusters are shown in (A) and (C) (full arrows). Normal hepatocytes were observed (dotted arrows) around the insulin-stained cells in the liver lobe. Glucagon-stained cells cluster are shown in (B) and (D) (full arrows). Normal hepatocytes were observed (dotted arrows) around the glucagon-stained cells in the liver lobe.
