Active caspase-3 expression induced in oral cancer cells in the SAS xenografts model using the Danshen crude. H&E staining and IHC were performed after administration of the Danshen crude, 5-FU, or PBS (a vehicle control). The SAS xenografts model stained active caspase-3. Immunodetectable proteins are stained brown and the nuclei are counterstained blue. Original magnification, 200×
