(6-4) PP-expressing cells were detected in human trachea after 222 nm irradiation. (A) Representative immunofluorescence images of (6-4) PP staining (magenta) in human trachea 10 min after CW 222 nm irradiation. Hoechst nuclei (blue). Pulsed 254 nm-irradiated samples were used as a positive control. Scale bar, 100 μm. (B) Representative immunofluorescence images of (6-4) PP staining (magenta) in human trachea 10 min after exposure to pulsed 222 nm light. Hoechst nuclei (blue). Scale bar, 100 μm.
