| Outline of Final Research Achievements |
We observed gastrointestinal interstitial cells such as interstitial cells of Cajal (ICC) and fibroblasts (fibroblast-like cells) using genetic labeling mice. We showed that fibroblasts in the musculature expressed c-Kit ligand SCF (stem cell factor) that is essential for ICC development. Using lacZ reporter mice, we showed that ICC and fibroblasts expressed zinc finger protein Gli1 and Gli2 known as glioma-associated oncogene. These proteins are transcription factors mediating the hedgehog pathway and regulate gastrointestinal tract development. Our findings suggest that ICC and fibroblasts are regulated by hedgehog signaling in development and maintenance of gastrointestinal tract.
