High-fat diet promotes apoptosis and macrophage infiltration in porcine auto-transplanted kidneys. Apoptotic cell death by TUNEL positive cell staining (A, scale bars represents 30 µm) and inflammatory ED1 positive cells infiltrated in graft by immunofluorescence staining (B, scale bars represents 40 µm) in normal diet (a) or high-fat (b) groups, 3 months after renal auto-transplantation surgery. *p < 0.05 vs. normal diet group; n = 5 in each group
