A Rapid and Accurate Bioluminescence-Based Migration Assay Permitting Analysis of Tumor Cell/Stromal Cell Interactions

Abstract

Bioluminescent tumor cell lines are used extensively in vivo to monitor tumor growth and metastasis but rarely used in vitro to follow tumor cell behavior. Tumor cell migration is frequently studied in vitro using transwell assays, however, current methods do not permit the co-incubation of tumor cells with different stromal cell types for analysis of the effects of intercellular cross-talk on tumor cell migration. We describe a novel migration assay using bioluminescent tumor cell lines that is rapid, accurate, and permits the study of the effects of tumor cell-stromal cell interactions on tumor cell migratory behavior.
