A compartmentalizing microfluidic device for investigating cancer stem cell migration is described. This novel platform creates a viable cellular microenvironment and enables microscopic visualization of live cell locomotion. Highly motile cancer cells are isolated to study molecular mechanisms of aggressive infiltration, potentially leading to more effective future therapies.

Cancer Cell Migration through Invadopodia

2023
Invadosome is a broad category of cell surface structures with proteolytic activity that degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However, invadopodia can...

An Introduction to Cell Motility and Migration

2023
Cell motility and migration play important roles in both normal biology and in disease. On one hand, migration allows cells to generate complex tissues and organs during development, but on the other hand, the same mechanisms are used by tumor cells to move and spread in a process known as cancer metastasis. One of the primary cellular machineries that make cell movement possible is an intracellular network of myosin and actin molecules, together known as “actomyosin”, which creates a...

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.
FAQs
Directional movement depends on coordinated sensing and force generation. Cancer cells detect chemical and mechanical cues, then reorganize the actin cytoskeleton, the filament network that produces cell shape and movement. Focal adhesions provide attachment points to the surrounding matrix, allowing traction as the cell advances. These linked events help explain differences in migratory behavior.
Epithelial-to-mesenchymal transition, or EMT, can increase motility and invasiveness by shifting tumor-cell behavior toward movement through surrounding tissue. In migration studies, EMT is therefore relevant as a biological state associated with greater dissemination potential, rather than merely a descriptive label. Comparing cells with different EMT-related behavior can help connect cellular changes to metastatic spread.
Proteases contribute by modifying the extracellular matrix around a tumor cell. This remodeling can change the physical environment that cells must cross and supports investigation of how local tissue structure affects invasion. Examining protease-dependent matrix modification alongside cytoskeletal remodeling and focal adhesion formation gives a more complete view of the coordinated mechanisms underlying cancer cell migration.
Migration assays and live-cell imaging provide complementary ways to study the process. Assays can be used to measure migratory behavior, while imaging follows movement over time and helps reveal how individual cells interact with their surroundings. Together, these approaches allow biologists to investigate metastatic potential and connect observable movement with underlying cellular mechanisms.
Researchers apply these models to examine interactions between tumor cells and their microenvironment. By observing movement in relation to surrounding conditions, they can investigate how chemical or mechanical cues influence behavior and assess patterns associated with dissemination. This context is important because migration is not studied as an isolated cell property; it is examined within the tissue environment that shapes metastatic progression.
Drug studies use migration assays and live-cell imaging to evaluate potential treatments that may inhibit invasion or dissemination. Observed changes in movement and related cellular behavior provide experimental outcomes for judging whether a treatment affects processes linked to metastasis. In biology, these models help identify therapeutic targets while also characterizing how cancer cells respond to intervention.
