Outline of Final Research Achievements

Pancreatic cancer shows an aggressive phenotype with a dismal prognosis despite of multimodal therapy. Notably, neural invasion is a life-threatening problem. In this study, we aimed to reconstruct microenvironment around pancreatic cancer cells. First, we developed novel mouse pancreatic cancer stem cells by introducing mutated KRAS, mutated p53, and CDK4 oncogenes common in human pancreatic cancer to mouse pancreatic stem/progenitor cells. Then, we established co-culture system between multipotent stem cells and pancreatic cancer cells. We found that both mouse embryonic stem cells and human induced pluripotent stem cells could differentiate into neural cells such as neuron or glia cells in vitro and in vivo. These results indicate that this system might be potent tool to develop novel treatment strategy for pancreatic cancer.
