Outline of Final Research Achievements

We identified subpopulation of CD51 highly expressed pancreatic stellate cells as tumor-promoting pancreatic stellate cells and CD146 highly expressed pancreatic stellate cells as tumor-suppressing pancreatic stellate cells. Endo180 expressed on pancreatic stellate cells was found to be associated with local invasion mechanism as a leading cell of tumor-promoting pancreatic stellate cells. Furthermore, we identified autophagy was involved in the activation of pancreatic stellate cells. In the mouse model, suppression of autophagy of pancreatic stellate cells reduced tumor development and metastasis. From these results, we clarified the possibility of a new treatment strategy by reprogramming cancer microenvironment.
