Fluorescence imaging of lung cancers xenografted on the CAM model. Representative of white light images of NSCLC and SCLC grafted on CAM before administration of photosensitizer (Fig 2A, B). Before incubation of Ce6-PVP, the CAM tumor xenografts were imaged under blue light illumination, to confirm that there was no autofluorescence. Tumor fluorescence images at 3 h post-topical administration of 1 mg/kg of Ce6-PVP under blue light illumination (Fig 2C, D).
