Abstract
Available mouse models for pancreatic ductal adenocarcinoma (PDAC) are limited by slow tumor development and failure to recapitulate key stromal and immune characteristics. Here, we present a protocol for generating a collagen hydrogel mouse model for orthotopic PDAC. We describe steps for embedding mouse pancreatic cancer cells in a dense collagen hydrogel and surgically implanting it into the mouse pancreas. Mouse PDAC tumors typically reach 1 cm in diameter by 10 days after implantation and show immune and stromal cell recruitment. For complete details on the use and execution of this protocol, please refer to Korah et al.(1).
