Bioluminescent imaging detects tumor prior to significant weight change Representative bioluminescent imaging of ID8 Luc2 implant at 2 (A) and 4 weeks (B) after injection. Mice are placed in the same positions for both images. (C) Average weight of mice at 2, 4, 5, and 8 weeks after tumor cell injection (x-axis), n = 32. (D) Average luminescent units at 2, 4, 5, and 8 weeks after tumor cell injection (x-axis), n = 32. *p < 0.05, **p < 0.01, ****p < 0.0001.
