Photodynamic Treatment of Tumor with Bacteria Expressing KillerRed
Fig 6
Histological sections of tissue showing the phototoxicity induced by KR-E. coli on CNE2 tumors.
The top panels demonstrate sections of CNE2 tumors that were injected with KR-E. coli, E. coli without KillerRed expression, and a physiological saline, and fixed before irradiation. The bottom panels demonstrate the preparations treated in the same way but fixed after irradiation with the orange light. All sections were H&E stained. The arrows indicate blood vessels of the tumor. Bar, 200 m.
