Clinicopathological study on cholangiolocellular carcinoma suggesting hepatic progenitor cell origin

Cholangiolocellular carcinoma (CLC), a subtype of cholangiocellular carcinoma (CC), is thought to originate from the ductules/canals of Hering, where hepatic progenitor cells (HPCs) are located. We investigated the clinicopathological features of 30 CLCs and their relationship to HPCs. We evaluated the expression of hepatocytic markers (hepatocyte paraffin-1, canalicular polyclonal carcinoembryonic antigen, and CD10), biliary/HPC markers...
