| Research Abstract |
Our current study revealed the role of Notch signaling not only in homeostasis of the intestinal epithelial tissue, but also in tissue regeneration, through regulation of epithelial cell proliferation and differentiation. In addition, we showed that among Notch ligands, Jag1, Dll1 and Dll4 are expressed in the human intestinal epithelial tissue, suggesting their involvement in regulation of epithelial cell differentiation. These results provide a novel basis for the establishment of therapeutic approaches aimed to promote mucosal regeneration of refractory inflammatory bowel disease patients.
