Ex vivo images of whole brain of mice injected with monocytes/macrophages loaded with red fluorescent microspheres. The presence and location of metastatic brain tumor foci (green fluorescence) and macrophages loaded with the red fluorescent microspheres was determined after resection using an optical imaging system. The images of green fluorescence (green fluorescent protein, gfp) and red fluorescence (red fluorescent particles, rfp) were taken after exposure times of 100 and 500 ms, respectively. The intensity of the fluorescence in different area of the brain is measured using the signal intensity bar. Values are normalized relative to the exposure times
