Figure 1From: Previously differentiated medial vascular smooth muscle cells contribute to neointima formation following vascular injurySchematic representation of the mTmG reporter strain. The mTmG reporter mice (Jackson strain: B6.129 (Cg)-Gt(ROSA)26Sortm4(ACTB-tdTomato,-EGFP)Luo/J ) contain a single copy of the transgene integrated into the ROSA 26 locus. The transgene cassette is comprised of a chimeric CMV, β-actin promoter driving the expression of a floxed membrane localized Tomato tandem dimer. Following cre-mediated excision the mTomato transgene is removed such that the CAG promoter now drives expression of membrane localized EGFP. The reporter mice were crossed with transgenic mice that express a tamoxifen regulated cre recombinase directed to smooth muscle cells by either the Myh11 promoter or the Acta2 promoter. Double heterozygous transgenic mice were used for all experiments.Back to article page
