| Outline of Final Research Achievements |
"Interstitial Cells of Cajal (ICC)" controls gastrointestinal motility as pacemaker cells. In this study, we tried to establish ICC specifically attacked mice using TRECK method, then we investigate gastrointestinal motility dysfunction and GFP-mesenchymal stem cells transplantation in vivo. Finally we aimed to establish the basis of ICC regenerative medicine as a new therapeutic target in gastrointestinal diseases by analyzing the linkage between the process and pacemaker function and gastrointestinal tract transporting ability. Two constructs were constructed by linking the expression regulatory region of about 15-20 kb in the ANO-1 and c-kit genes to the human-derived DT receptor (hDTR) / loxp sequence gene and the Cre recombinase gene, and transgenic (Tg) Mouse was attempted. We are now establishing several transgenic mice, and investigating rate of gene expression.
