An In Vitro Three-Dimensional Organotypic Model to Analyze Peripancreatic Fat Invasion in Pancreatic Cancer: A Culture System Based on Collagen Gel Embedding
Three-dimensional culture systems reflect biological environments better than conventional two-dimensional culture. Additionally, three-dimensional culture is a strong experimental tool to analyze direct interactions between cancer cells and stromal cells in vitro. Herein, we describe protocols for an organotypic fat invasion model that is a novel culturing system mimicking the extrapancreatic invasion of pancreatic adenocarcinoma (PDAC). This novel model is based on the collagen I gel embedding method and enables us to analyze the functional and histological interactions between cancer cells and adipose tissue.
