Figure 1. A: Green fluorescent protein-red fluorescent protein (GFP-RFP)-expressing dual-color XPA-I human pancreatic cancer cancer cells in vitro. Cancer cells were initially transduced with RFP and the neomycin-resistance gene. The cells were subsequently transduced with histone H2B-GFP and the hygromycin-resistance gene. Double transformants were selected with G418 and hygromycin, and stable clones were established. Images were captured under FV1000 confocal microscopy (28). Bi-Bii: High-magnification imaging of XPA-I pancreatic cancer cells and stellate cells in the liver of cyan fluorescent protein (CFP)-expressing nude mice. A, B: XPA-I-GFP-RFP pancreatic cancer cells in the host liver 3 hours after splenic injection. White arrows indicate XPA-1 pancreatic cancer cells. Biii, Biv: Twenty-eight days after co-injection of XPA-I-GFP-RFP pancreatic cancer cells and RFP stellate cells, liver metastases were observed in the host CFP nude mice. White arrows indicate XPA-I-GFP-RFP pancreatic cancer cells. Yellow arrows indicate RFP stellate cells. White arrow in Biv shows dividing cancer cells. Imaging was performed with a FV1000 confocal microscope (Olympus) (24).
