| Summary |
The aggressiveness of pancreatic ductal adenocarcinoma (PDAC) is affected by a tumor microenvironment (TME). In this study, to recapitulate PDAC TME ex vivo, we cocultured patient-derived PDAC cells with mesenchymal and vascular endothelial cells derived from human induced-pluripotent stem cells (hiPSCs) to create a fused pancreatic cancer organoid (FPCO) in air–liquid interface. FPCOs were further induced to resemble two distinct parts of a PDAC tissue. Owing to various types of cancer associated fibroblasts (CAFs) derived from hiPSCs, the TME consisted of abundant extracellular matrix proteins, which likely conferred strong drug resistance to PDAC cells in one type of FPCOs. Because of re-proliferation capacity of PDAC cells after anticancer drug treatment, the other FPCO is the first culture system for investigating PDAC recurrence. Introducing hiPSC technology, we have created, for the first time, the PDAC organoids representing the heterogeneity of PDAC tissue, a potential platform for screening anticancer drugs.

| Overall design |
Two types of fused pancreatic cancer organoid (FPCO) generated by patiend-derived pancreatic cancer organoids(PCOs), hiPSC-derived mesenchymal cells (hiPSC-MC) and vascular endothelial cells (hiPSC-EC), and their materials. In addintion, bone marrow mesenchymal stem cell (BMMSC) and patient-derived cancer associated fibroblast (CAF) as comparison target with FPCO-CAF.
