Figure 1.

Optical imaging of PC14PE6 and NCI‐H441 cells in orthotopic lung cancer models. (A) PC14PE6/EF‐Luc and (B) NCI‐H441/pEF‐Luc cells were injected into the left lung. When tumor formation was confirmed by bioluminescent images, the mice were randomized into paclitaxel (PTX)‐treated (PTX) and untreated (control) groups. The images were taken on the indicated day, in which day 1 is the first treated day. The mice in the figure are representative of each group.
