ANO1 and intrahepatic cholangiocarcinoma: Our results showed that, in the N and S groups, DOG1-like immunoreactivity (DOG1-LI) was localized in two distinct populations of ICC, one population with processes and numerous branches forming a cellular network between the circular and longitudinal muscle layers at the level of the myenteric plexus (ICC-MY), and a second population at the level of the deep muscular plexus in the circular muscle layer (ICC-DMP).
