Figure 7.
Representative light and fluorescence images of tumor tissues and organs from the experimental (FITC-NYZL1) (rows 2–3) and control (FITC-svNYZL1) (row 4) groups. Columns A–G show tumor tissue, heart, liver, spleen, lungs, kidneys and bladder. (A1–G1) Light images. (A2–G2) Images of fluorescence under blue light. (A3–G3) Fluorescence images of frozen sections of the tumor tissues and organs from the experimental group (FITC-NYZL1). Obvious green fluorescence can be found in the tumor tissue (A3). (A4–G4) Fluorescence images of frozen sections of the tumor tissues and organs from the control group (FITC-svNYZL1). No green fluorescence can be found in the tumor tissue (A4). Green regions indicate fluorescence of the FITC-NYZL1 probe, while blue regions represent fluorescence of the nucleus after DAPI counterstaining (magnification, ×200).
