| Outline of Final Research Achievements |
Endothelia in the arterial and venous circulation are heterogeneous in nature. In order to understand their heterogeneity, we developed novel BAC transgenic mice with cDNA encoding fusion proteins of a fluorescent protein, EGFP or mCherry, and a ribosomal protein L10a under control of the endothelial cell-specific thrombomodulin (TM) or endothelial cell protein C receptor (EPCR) promoter. We compared the expression intensities of transcribing endothelial-specific markers before and after immunoprecipitation with anti-EGFP antibody or anti-mCherry antibody and found that those markers are increased merely 2-3 fold after immunoprecipitation. We further examined the immunofluorescence staining of the heart and lung of the transgenic mice using anti-EGFP antibody or anti-mCherry antibody but failed to detect the endothelia positive for the antibody staining. We concluded that novel BAC transgenic mice we established showed low expression of EGFP-L10a or mCherry-L10a in endothelia.
