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

Figure 6 Desmin immunostaining. The desmin positive area confirmed the regeneration of smooth muscle. Meanwhile, the desmin positive area was significantly larger in group A than group B. A: Desmin immunostaining of the animal-derived artificial bile duct site in group A (magnification: 20 ×); B: Desmin immunostaining of duodenal papilla in group A (magnification: 20 ×); C and D: Desmin immunostaining of the animal-derived artificial bile duct site in group B (magnification: 20 ×); E and F: Desmin immunostaining of the distal normal bile duct in group B (magnification: 20 ×).
