Pancreatic ductal adenocarcinoma (PDAC) continues to be one of the most lethal human malignancies with a poor prognosis due to systemic metastasis and a high recurrence rate. Interactions between tumor and stromal cells play a critical role in tumor progression. However, the interaction between PSCs and pancreatic cancer cells (PCCs) and the underlying mechanisms are poorly understood. Coculture system with PSCs and PCCs is very useful technique platform for the in vitro and in vivo study of the interaction between these two cellular components. In this protocol, we aim to describe the cytokine profiling technique for in vitro study of PSC-PCC intercellular communication, and orthotopic xenografting animal model with coinjection of primary PSCs and PCC cell line.
