Our previously established SACC-83 and SACC-LM cell lines have identical STR profiling, and express epithelial markers such as pan-cytokeratin and cytokeratin AE1, and the luminal markers such as CK8/18 and S100P, indicating that both cell lines were originated in oral adenoepithelial cells and not contaminated by other cancer cell lines [8]. This evidence concerns the gene S100P and cancer.
