title: Specific monitoring of cardiomyogenic and endothelial differentiation by dual promoter-driven reporter systems in bone marrow mesenchymal stem cells.
abstract: Vectors encoding reporter genes driven by cardiac specific myosin light chain-2v (MLC-2v), endothelial cell-specific Flk1 or Tie2 promoters were constructed. The cardiac differentiation-monitoring vector (pMLC-2v-DsRed), endothelial cell-specific monitoring vectors (pFlk1-EGFP, pTie2-EGFP) as well as the dual promoter driven-reporter genes (pMLC-2v-DsRed-Flk1-EGFP, pMLC-2v-DsRed-Tie2-EGFP) were specifically expressed in the Sca-1(+) bone marrow mesenchymal stem cells (BMMSCs) with cardiomyogenic or endothelial lineage differentiation. The cardiac or endothelial cell-specific promoter-driven reporter vectors provide important tools for the study of stem cell fate and differentiation in vitro and future stem cell therapy for ischemic cardiomyopathy.
