The tumor microenvironment plays a vital role in therapeutic resistance in pancreatic adenocarcinoma. We have created a 3D model to study the tumor microenvironment ex vivo that integrates tumor cells with tumor associated macrophages (TAMs) and cancer associated fibroblasts (CAFs). The microtumor model recreates the complex histology of a primary tumor and can be analyzed histologically or with viability assays for therapeutic testing. Microtumors demonstrate increased resistance to gemcitabine when compared to tumor cells alone in a 3D spheroid, highlighting the contribution of TAMs and CAFs when designing models for therapeutic testing.
