Aims: Referring to the recently updated ‘hallmarks of cancer’ by Hanahan and Weinberg (Cell, 2011) the cancer stem cell model is now accepted as a valid concept of carcinogenesis. The aim of this study was to investigate the expression of putative markers of stem and progenitor cells in a human biliary tract cancer (BTC) tissue microarray (TMA). Materials and Methods: Specimens (n=34) from surgically resected BTC between 1997 and 2010 with complete clinical follow-up data and histopathological records were included to prepare TMAs from tumor center and margin as well as adjacent normal tissue. These TMAs were ch…
