Abstract
Visualization of biological events in real time in vivo has become a crucial to understand immune responses. We have been established novel visualization tools for life of immune cells: proliferation, cell death, and migration. Fucci-transgenic mice allow us to visualize cell cycle phases by reciprocal expression of mKusabira-Orange2 in G1 phase and mAzami-Green in S/G2/M phase. Caspase-3 indicator SCAT3.1 knock-in mice visualize cell death by changing color. Photoconvertible proteins, Kaede and KikGR expressing mice track cell movement between organs by labeling immune cells as red color. Here, I will introduce how to use and visualize these mice. These techniques will help to understand immune system in the living whole body.
