In Vivo Bioluminescence and Fluorescence Imaging: Optical Tool for Cancer Research

In vivo whole-body imaging, using optical tools based on bioluminescence and fluorescence detection, offers tremendous opportunities to specifically determine the spatiotemporal resolution of cancer cells within the tested animals. This enables the study of many aspects of cancer biology, including cell proliferation, trafficking, and invasions. The antitumor therapeutic properties of various tested compounds (e.g., CD19 CAR-T cells, used for cancer immunotherapy) can be monitored within the same animal at different time points, significantly reducing the number of animals used in the study as indicated in this method.
