Methods to visualize metastasis exist, but additional tools to better define the biological and physical processes underlying invasion and intravasation are still needed. One difficulty in studying metastasis stems from the complexity of the interface between the tumor microenvironment and the vascular system. Here we report the development of an investigational platform that positions tumor cells next to an artificial vessel embedded in an extracellular matrix (ECM). On this platform, we used live-cell fluorescence microscopy to analyze the complex interplay between metastatic cancer cells and a functional artificial microvessel which was lined with endothelial cells. The platform recapitulated known interactions, and its use demonstrated the capabilities for a systematic study of novel physical and biological parameters involved in invasion and intravasation. In summary, our work offers an important new tool to advance knowledge about metastasis and candidate anti-metastatic therapies.
