In vivo images of MDA-MB-231-Luc-GFP tumor tissue in the liver and abdominal area. a, b Images of tumor tissue implanted in the liver and, consequently tumor invasion and migration of cells in the abdominal cavity. c, d Intensity profiles are corresponding to the area along the arrow axis. Plot profiles of Luc in the liver and abdomen weeks are indicated in black and magenta, respectively. e Real-time quantification of total tumor-fluorescence surface area (mm²) detected over 3 weeks post-tumor tissue implantation. f Ex vivo tissue examination postmortem. Scale bar: 10 mm
