The Transwell Migration Assay

Cells migration in response to chemical cues is crucial to development, immunity and disease states such as cancer. To quantify cell migration, a simple assay was developed in 1961 by Dr. Stephen Boyden, which is now known as the transwell migration assay or Boyden chamber assay. This set-up consists an insert which separates the wells of a multiwell plate into top and bottom compartments. Cells whose migration is to be studied are seeded into the top compartment and the chemoattractant...

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...

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.

This protocol demonstrates methods used to establish 2D and 3D environments in custom-designed electrotactic chambers, which can track cells in vivo/ex vivo using time-lapse recording at the single cell level, in order to investigate galvanotaxis/electrotaxis and other cellular responses to direct current (DC) electric fields (EFs).
FAQs
Movement in a 3D migration assay is shaped by more than cell motility alone. Matrix composition changes the surrounding extracellular environment, while pore structure can influence whether cells move through available spaces. Chemical gradients add directional cues, allowing experiments to examine how environmental conditions alter migration behavior.
Embedding cells within an extracellular matrix examines movement through a defined three-dimensional environment, whereas releasing cells from spheroids focuses on how a multicellular structure expands or disperses. These configurations provide complementary views of migration, helping investigators relate individual cell movement to behavior emerging from organized tumor-cell groups.
Time-lapse imaging converts cell movement into measurable outcomes rather than relying only on endpoint observations. Migration distance indicates how far cells travel, speed describes the rate of movement, and directionality shows whether movement follows a consistent path. Together, these measures distinguish different changes in migratory behavior after environmental or experimental manipulation.
A typical workflow establishes cells either within an extracellular matrix or in a spheroid-based format, then maintains the chosen experimental conditions while movement is recorded over time. Time-lapse imaging captures migration, and subsequent analysis quantifies distance, speed, or directionality. Comparing these measurements across conditions reveals how the tested variable affects movement.
This approach is useful when researchers need to evaluate tumor-cell invasion in an environment that includes three-dimensional structural features. It can characterize how cancer cells move through matrix, examine interactions with stromal cells, and compare migratory behavior under different experimental conditions. The resulting measurements help connect cell movement with processes associated with cancer progression.
Researchers can compare migration measurements before and after applying a drug or introducing a genetic change. Differences in distance, speed, or directionality indicate whether the intervention alters movement through the three-dimensional environment. In cancer research, these comparisons help assess effects on metastatic behavior and support investigation of potential anti-invasive therapies.
