| Outline of Final Research Achievements |
The present study revealed the following. (1) Perivascular markers, NG2 and/or PDGFRβ, are expressed in the stroma of pancreatic tumor. (2) NG2/PDGFRβ-positive cancer-associated fibroblasts increase the migratory and invasive abilities of pancreatic cancer cells. (3) CD51 is widely expressed in the stroma of pancreatic tumor. (4) Knockdown of CD51 in activated pancreatic stellate cells decreases the production of extracellular matrix, such as collagenⅠand fibronectin. (5) Knockdown of CD51 suppresses the growth of pancreatic cancer cells in vivo.
