Figure 1. Reporter gene expression profile of macrophage populations in Cx3cr1gfp/+, Cx3cr1cre/+:R26-yfp and Tamoxifen-treated Cx3cr1creER/+:R26-yfp mice.
(A) Schematic of modified Cx3cr1 loci. The Cx3cr1cre and Cx3cr1creER mice were crossed to R26-yfp mice, in which irreversible induction of YFP expression is induced upon Cre recombinase expression and activation, respectively.
(B & C) Flow cytometric analysis of CX3CR1+ (B) and CX3CR1 (C) mononuclear phagocyte populations of Cx3cr1gfp/+, Cx3cr1cre/+:R26-yfp and Cx3cr1creER/+:R26-yfp mice. Cx3cr1creER/+:R26-yfp mice were treated for 4 weeks with Tamoxifen prior to analysis. Results are representative of 6 mice per group.
