Outline of Final Research Achievements |
We established 3D in vitro collagen invasion assay to investigate leading cell. We found that Pancreatic stellate cells (PSCs) frequently invaded a collagen matrix with cancer cells, which invaded behind the invading PSCs, and an increase in the number of invading cancer cells in co-cultures with PSCs. Invading PSCs changed the alignment of collagen fibers, resulting in ECM remodeling and an increase in the parallel fibers along the direction of invading PSCs. We elucidate that one of the ECM remodeling factor of PSCs is Endo180. Endo180 knockdown in PSCs attenuated the invasive abilities of PSCs and co-cultured cancer cells, and decreased the expression level of phosphorylated myosin light chain 2 (MLC2). Our findings suggest that PSCs lead the local invasion of pancreatic cancer cells by physically remodeling the ECM, possibly via the function of Endo180, which reconstructs the actin cell skeleton by phosphorylation of MLC2.
