| Outline of Final Research Achievements |
The application of primary cultures preserving intrinsic property of cancers holds promise for serving human resources to uncover core pathway guiding novel therapy and to provide patient-specific tumor antigens. In the current study, we sought to develop a culture system that can allow pancreatic neoplasia at various stages to adapt in vitro microenvironment without losing tumor forming capability in vivo. The primary culture by combining tumor oraganoid isolation and conditional reprogramming facilitated to rebuild physiological tumor structure by transplanting to immunodeficient mice, whereas most commercially available cell lines did not. Sequencing data of the primary culture indicated these tumor cells include heterogeneity of the primary tumors, providing useful model to learn clonal evolution of the precursors. These studies demonstrate the general utility of a tractable tumor culture for human cancer modeling and therapeutic strategy against pancreatic neoplasms.
