Immunohistochemical assay. a APOF is highly expressed in choledochal cyst. A APOF is lowly expressed in CCA. b ITGAV is poorly expressed in choledochal cyst. B ITGAV is moderately expressed in CCA. c, C CASK was strongly positive expressed in CCA. d, D CASK was moderately positive expressed in CCA. e, E CASK was weakly positive expressed in CCA. f, F CASK was completely negative expressed in interlobular bile duct.
