Extrahepatic bile duct reconstruction in pigs with heterogenous animal-derived artificial bile ducts: A preliminary experience

Figure 4 Hematoxylin/eosin staining of the animal-derived artificial bile duct site. No marked transmural neutrophil and lymphoplasma cell infiltration was observed. A: Hematoxylin/eosin (H/E) staining of a 6 mo survival pig in group A (magnification: 20 ×); B: H/E staining of a 12 mo survival pig in group B (magnification: 20 ×); C: H/E staining of a 6 mo survival pig in group A (magnification: 40 ×); D: H/E staining of a 12 mo survival pig in group B (magnification: 40 ×); E and F: H/E staining result of neovascularization was marked in group A and B (magnification: 20 ×).
