Commonly used, highly accessible methods for examining cell migration and invasion in vitro are described. The first method is the cell wound closure assay that measures cell motility. The second method is the transwell migration and invasion assay that assesses the chemotactic and invasive capacity of cells.

Invasion Assay Using 3D Matrices

The extracellular matrix (ECM) is a network of molecules that provide a structural framework for cells and tissues and helps facilitate intercellular communication. Three-dimensional cell culture techniques have been developed to more accurately model this extracellular environment for in vitro study. While many cell processes during migration through 3D matrices are similar to those required for movement across rigid 2D surfaces, including adherence, migration through ECM also requires cells...

In this protocol, we describe the dissection of placentae from the mouse on pregnancy d10.5, followed by isolation of trophoblast cells using a Percoll gradient. We then demonstrate use of the isolated cells in a matrigel invasion assay.
FAQs
The matrix coating provides a physical barrier that cells must cross before they are counted as invasive. This models movement through extracellular material, a feature associated with tissue invasion. The coating therefore helps distinguish cells capable of penetrating a tissue-like barrier and links measured motility with the invasive behavior relevant to disease progression.
Placement of a chemoattractant in the lower chamber creates a directional cue across the membrane. Cells are assessed not only for movement, but for movement toward a defined stimulus. This arrangement helps investigators examine how strongly cells respond to attractant-driven conditions and whether a treatment or genetic change alters that directional invasive behavior.
Changes in the number of cells that cross the barrier can be used to investigate molecular regulators of motility. If a genetic change or drug treatment modifies the invasion readout, researchers can compare invasive capacity between conditions. The result provides a functional measure of altered behavior while connecting molecular regulation with cell dissemination.
A typical workflow places cells in the upper chamber, supplies the lower chamber with a chemoattractant, and allows movement across the matrix-coated porous membrane. Afterward, cells that have invaded are stained and quantified. Keeping these stages distinct converts cell movement into a measurable endpoint for comparisons among experimental conditions.
Quantification focuses on stained cells that have crossed the membrane in the assay system. Comparing this readout across samples indicates whether invasive capacity has increased or decreased. These comparisons are useful for testing drug effects or examining genetic changes because the endpoint captures a measurable behavioral outcome associated with the ability to invade.
Cell invasion assays are particularly relevant to cancer biology because they provide an in vitro model for dissemination and metastatic behavior. Researchers can use them to characterize molecular regulators of motility, evaluate drug responses, or compare cells after genetic modification. These applications connect a controlled cell-based experiment with broader questions about disease mechanisms and therapeutic responses.
