Cell migration and invasion assays

Area of Science:

• Cell Biology
• Molecular Biology
• Biochemistry

Background:

• Cell migration and invasion are fundamental biological processes, essential for embryonic development and adult tissue homeostasis.
• Aberrant cell motility is a hallmark of various diseases, including cancer metastasis and inflammatory conditions.
• Ras GTPases, especially the Rho subfamily, are key regulators of the cellular machinery governing cell movement.

Purpose of the Study:

• To present a comprehensive collection of experimental protocols for quantifying cell migration and invasion.
• To provide researchers with standardized methods to investigate the roles of GTPases in cell motility.
• To facilitate the study of disease mechanisms linked to dysregulated cell movement.

Main Methods:

• Monolayer wound healing assay for straightforward assessment of collective cell migration.
• Microliter-scale migration assay for analyzing cell behavior on defined extracellular matrices.
• Transwell Matrigel invasion assay for quantifying tumor cell penetration through a basement membrane-like barrier.
• Organotypic assay to evaluate glioma cell invasion within a 3D rat brain slice model.

Main Results:

• Established and validated protocols for assessing distinct aspects of cell migration and invasion.
• Demonstrated the utility of these assays in studying GTPase-mediated cellular functions.
• Provided a toolkit for researchers to investigate cell motility in various biological contexts.

Conclusions:

• The presented protocols offer robust and versatile methods for studying cell migration and invasion.
• These assays are critical for understanding the molecular mechanisms underlying normal development and disease pathogenesis.
• This collection serves as a valuable resource for the cell biology and cancer research communities.
