摘要

胰腺导管腺癌（PDAC）类器官模拟肿瘤微环境（TME）是确定TME如何影响PDAC恶性肿瘤的有效工具。我们提出了一种使用患者来源的PDAC细胞和人类诱导的多能细胞来源的内皮细胞和间充质细胞生成融合的胰腺癌类器官（FPCO）的方案，该方案部分地复制了TME，包括异质癌症相关成纤维细胞（CAFs）。我们还描述了分析FPCO特性的过程。FPCO可为建立可靠的药物筛选系统提供平台。有关本协议使用和执行的完整细节，请参见Takeuchi et al.1。

Protocol for generating a pancreatic cancer organoid associated with heterogeneous tumor microenvironment.

Pancreatic ductal adenocarcinoma (PDAC) organoids that simulate the tumor microenvironment (TME) are an effective tool to identify how TME affects PDAC malignancy. We present a protocol for generating a fused pancreatic cancer organoid (FPCO) that partly reproduces the TME, including heterogeneous cancer-associated fibroblasts (CAFs), using patient-derived PDAC cells and human-induced pluripotent cell-derived endothelial and mesenchymal cells. We also describe the procedure for analyzing FPCO characteristics. FPCO can provide a platform for establishing a reliable drug screening system. For complete details on the use and execution of this protocol, please refer to Takeuchi et al.¹.
