These tumorigenic cancer cells possess a specific profile of surface markers such as CD29, CD34+, CD38−, CD166, CD133+/−, Lin, stem cell antigen 1 (Sca-1), epithelial cell adhesion molecule or (EpCAM) associated with stemness and that may be used to isolate them by means of fluorescence activated cell sorting (FACS) or other immunoselection procedures [20,21,22]. This evidence concerns the gene EPCAM and cancer.
