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

Figure 7 Masson’s trichrome staining. The Masson’s trichrome staining showed marked regeneration of the submucosal connective tissue and no significant differences between the animal-derived artificial bile duct site and the normal bile duct. The submucosal connective tissue was more regular and thicker in group B than that in group A. A: Masson staining of the animal-derived artificial bile duct site in group A (magnification: 20 ×); B: Masson staining of duodenal papilla in group A (magnification: 20 ×); C and D: Masson staining of the animal-derived artificial bile duct site in group B (magnification: 20 ×); E and F: Masson staining of the distal normal bile duct in group B (magnification: 20 ×).
