Matrix Degradation Assay to Measure the Ability of Tumor Cells to Degrade Extracellular Matrix

Methods Mol Biol. 2021:2294:151-163. doi: 10.1007/978-1-0716-1350-4_11.

Abstract

During the metastatic process, carcinoma cells form invadopodia, F-actin enriched protrusive structures, to degrade the extracellular matrix (ECM) in order to invade the surrounding stroma and intravasate into the circulatory system. In this chapter, we describe the 2D-fluorescent matrix degradation assay, a highly sensitive and reproducible in vitro method used to measure invadopodia-mediated ECM degradation. We provide a detailed protocol on how to prepare the glass coverslips with fluorescent gelatin matrix and a standardized method to quantify gelatin degradation and invadopodia formation in order to evaluate cell invasion.
