helmets The ability of cancer cells to migrate through a complex three-dimensional (3D) environment is a hallmark event of cancer metastasis.Therefore, an in vitro migration assay to evaluate cancer cell migration in a 3D setting is valuable to examine cancer progression.Here, we describe such a simple migration assay in a 3D collagen-fibronectin gel for observing cell morphology and comparing the migration abilities of cancer cells.We describe below how to prepare the collagen-fibronectin gel castings, how to set up time-lapse recording, how to draw single-cell trajectories from movies and extract key parameters that characterize cell motility, such as cell speed, directionality, mean square displacement, and directional water bottle persistence.In our set-up, cells are sandwiched in a single plane between two collagen-fibronectin gels.

This trick facilitates the analysis of cell tracks, which are for the most part 2D, at least in the beginning, but in a 3D environment.This protocol has been previously published in Visweshwaran et al.(2018) and is described here in more detail.
