Outline of Final Research Achievements |
The aim of this study was to clarify the mechanism and contribution of stellate cells and immune cells in of remodeling extracellular matrix of pancreatic cancer. We isolated activated stellate cells (PSCs) from human pancreatic cancer and analyzed the structure of collagen matrix produced by PSCs. Under hypoxic condition, the alignment of collagen fiber became parallel and enhanced motility of pancreatic cancer. We identified PLOD2 as a major collagen modifying enzyme under hypoxia. We also identified collagen matrix produced by PSCs was denser and stiffer than that of adipose tissue derived stromal cells, which means heterogeneity of stromal cells in pancreatic cancer influences mechanical structure of extracellular matrix in pancreatic cancer.
