External images of B16F0-GFP colonizing the liver. A metastatic lesion of B16F0-GFP in the liver growing at a depth of 0.8 mm after portal vein injection was externally imaged through the abdominal wall of the intact nude mouse. (A) An external image of multilobe liver metastases of the B16F0-GFP cells (large arrows). (B) An external image of small liver metastatic lesions of approximately 1.5 mm in diameter (small arrows) and other larger metastatic lesions (large arrows).
