Fig. 2From: Clinical implications of pediatric biliary intraepithelial neoplasia diagnosed from a choledochal cyst specimenHematoxylin and eosin (H&E) and immunohistochemical staining. H&E staining and immunohistochemical staining for p53, Ki67, MUC1, and S100P in normal bile duct tissue and low- and high-grade biliary intraepithelial neoplasia (BilIN) arising from a choledochal cyst. BilINs exhibit increased expressions of p53, Ki67, and MUC1 compared to those in normal biliary epithelial tissue. High-grade BilIN displays higher levels of p53 and Ki67 expression than low-grade BilIN. S100P expression does not differ between cases.Back to article page
