[Visualization of microgilia in living tissues using Iba1-EGFP transgenic mice].Brain Nerve 2007; 59(7):763-72BN
Microglia are thought to play pathologic and regenerative states of the brain. We generated transgenic mice with expression of EGFP under the control of the Iba1 promoter, a specific protein of macrophages/microglia. In this mice, we observed the EGFP-positive cells in living tissues and brain, and we could visualize the EGFP-expressing microglia in living brain sections from embryonic stage to adult stage. This method is useful tool to study the microglial dynamic movement in vivo, and provide the new finding of role of microglia.
