Outline of Final Research Achievements

Through the studies of the current project, results were acquired in the following areas: 1) Identification of Dll1+ve or Dll4+ve cells in inflamed and non-inflamed intestinal epithelium, and the functional relevance of those cells, 2) Comprehensive analysis of gene expression in Notch and TNF-α pathway activated cells, which constitute the regenerative epithelium inbt he colitic mucosa and 3) Identification of a distinct intestinal stem cell population that appears at the recovery phase of colitis.
