Squamous cell carcinomas (SCCs) are one of the most frequent solid cancer types in humans and are derived from stratified epithelial cells found in various organs. SCCs derived from various organs share common important properties, including genomic abnormalities in the tumor suppressor gene p53. There is a carcinogen-induced mouse model of SCC that produces benign papilloma, some of which progress to advanced carcinoma and metastatic SCCs....
