  • NOTE: Histologic examination of tumor type was done at the termination of the photocarcinogenesis protocol at 35 weeks. The tumors or suspected carcinomas were obtained and processed for histologic evaluation following conventional H&E staining.

  • Abbreviations: AK, actinic keratosis; SCC, squamous cell carcinoma; n, number of tumor-bearing mice in each group.
