Outline of Final Research Achievements

The purpose of this study is to conduct foundational research for development of a novel technique for the detection and isolation of disseminated cancer cells with our original gene expression systems. The reporter gene, GFP expression under the system was investigated in various cancer and normal cells and it was confirmed that the system can increase the cancer cell-specific gene expression. It was also confirmed that the GFP encoding plasmid system allowed in vitro selective visualization of floating human cancer cells in mixed cell culture containing 10000-fold more normal blood cells.
