| Outline of Final Research Achievements |
The aim of this study is classifying the pancreatic stellate cells that are the important factor in the tumor environment, and identifying the specific cell population which strongly enhances the tumor malignancy. CD271 positive pancreatic stellate cells were at the tumor periphery and correlated with patients’ prognosis negatively. CD146 positive pancreatic stellate cells existed around the PanIN lesions and correlated with patients’ prognosis negatively. These findings indicates that pancreatic stellate cells are the functionally heterogenetic population and targeting the specific group of stellate cells could be the novel therapeutic strategy.
