Description
Cell motility, formally annotated as GO:0048870, is the biological process by which a cell moves itself in a controlled manner from one location to another. This process is fundamental to life: it shapes embryos, allows immune cells to patrol tissues, enables fibroblasts to close wounds, and permits cancer cells to invade and metastasize. Because motility is so central, its dysregulation is a hallmark of numerous pathologies, including tumor progression, ocular disorders such as glaucoma, and developmental defects. Researchers studying cell motility therefore need robust definitions, mechanistic frameworks, and experimental models to dissect how cells move and how to intervene therapeutically. The QuickGO definition provides a precise scope: any process involved in the controlled self-propelled movement of a cell that results in translocation of the cell from one place to another. This article integrates authoritative ontology information with real PubMed literature to provide a research-grade overview of cell motility, its molecular basis, disease relevance, and the CRISPR and imaging methods used to study it.

What Is GO:0048870?
In simple terms, cell motility is the ability of a cell to actively move from one spot to another under its own control. According to the Gene Ontology, GO:0048870 cell motility encompasses any process involved in the controlled self-propelled movement of a cell that results in translocation of the cell from one place to another. This definition distinguishes motility from passive displacement: the cell must generate forces and regulate directionality. It includes diverse modes such as crawling on a substrate, swimming, blebbing, and amoeboid movement. The term is a biological process and is often used interchangeably with cell locomotion, cell movement, and movement of a cell.
Why Is cell motility Important in Cell Biology?
Cell motility is essential for normal physiology and is a major driver of disease when misregulated. It underlies embryonic morphogenesis, immune cell trafficking, and tissue repair, while aberrant motility promotes cancer invasion, metastasis, and ocular pathologies such as glaucoma. Understanding the molecular mechanisms of motility therefore has broad implications for developmental biology, immunology, oncology, and regenerative medicine. Moreover, motility is a quantifiable phenotype that can be manipulated genetically, making it an excellent readout for functional genomics and drug discovery.
• Cell motility is required for embryonic development and organ formation.
• It enables immune cells to migrate to sites of infection and inflammation.
• Fibroblast and epithelial motility is central to wound healing and tissue regeneration.
• Cancer cells exploit motility programs to invade surrounding tissues and metastasize.
• Dysregulated motility contributes to glaucoma and other ocular diseases.
• Motility assays are used to screen for anti-metastatic and anti-fibrotic drugs.
• Single-cell motility profiling reveals heterogeneity in migration phenotypes.
• Biophysical models of adhesive wetting link motility to substrate mechanics.
• Planar cell polarity signaling regulates directional motility in development.
• Amoeboid and bleb-based motility provide alternative strategies when adhesion is limited.
What Happens During cell motility?
Initiation and polarization
In simple terms: The cell decides which way to go and gets ready to move.
Cell motility begins with the establishment of front-rear polarity, often in response to chemical or mechanical cues. This involves the localized activation of Rho-family GTPases and the reorganization of the actin cytoskeleton to form protrusive structures such as lamellipodia and filopodia. Planar cell polarity signaling through Wnt-Frizzled pathways contributes to directional migration in developmental contexts.
Protrusion and adhesion
In simple terms: The cell pushes its front edge forward and grabs onto the surface.
Actin polymerization drives membrane protrusion at the leading edge, while integrin-mediated adhesions form new contacts with the extracellular matrix. The balance between protrusion and adhesion determines the efficiency of forward movement. Adhesive wetting phenomena describe how cells spread and move on substrates with different mechanical properties.
Contraction and retraction
In simple terms: The cell pulls its back end forward using molecular motors.
Myosin II-generated contractile forces, together with actin filament disassembly, retract the rear of the cell and translocate the cell body forward. In some contexts, myosin-independent amoeboid motility can also drive movement through bleb-based mechanisms. Plasma membrane blebbing is a specialized mode of motility that does not require strong adhesion.
Microtubule contributions
In simple terms: Microtubules act like tracks that help organize and steer the cell.
Microtubules contribute to cell motility by regulating polarity, adhesion turnover, and intracellular transport, particularly in three-dimensional environments. Their dynamics are essential for efficient migration through complex matrices.
Termination and recycling
In simple terms: The cell stops moving when it reaches its destination or receives a stop signal.
Motility is terminated by signals that promote adhesion disassembly and actin depolymerization, allowing the cell to re-establish a stationary state. This step is crucial for preventing uncontrolled migration and is often dysregulated in cancer.

How Is cell motility Regulated?
Cell motility is regulated at multiple levels, including Rho-family GTPase signaling, integrin-mediated adhesion, and planar cell polarity pathways. Wnt-Frizzled signaling controls directional migration during development. Adhesive wetting and substrate mechanics also modulate motility efficiency. In disease contexts such as glaucoma, altered motility of trabecular meshwork cells contributes to pathology, and therapeutic targeting of motility pathways is being explored.
cell motility and Human Disease
| Gene | Disease / Biology | Potential Experimental Model |
|---|---|---|
| RHOA | Cancer metastasis | Knockout in cancer cell lines; invasion assays |
| WNT5A | Developmental polarity defects | Point mutation knock-in in zebrafish or mouse |
| MYH9 | Glaucoma-associated motility | Overexpression in trabecular meshwork cells |
| ITGB1 | Fibrosis and cancer | Knock-in of tagged integrin for imaging |
| EZR | Amoeboid motility in cancer | Knockout in melanoma cells; blebbing assays |
Cancer invasion and metastasis
Tumor cell motility is a critical step in the metastatic cascade, enabling cancer cells to escape the primary tumor and colonize distant organs. Multiple modes of motility, including mesenchymal and amoeboid, allow cancer cells to adapt to different microenvironments. Targeting motility pathways is a promising anti-metastatic strategy.
Glaucoma
In glaucoma, altered motility of trabecular meshwork cells and other ocular cell types contributes to increased intraocular pressure and optic nerve damage. Recent reviews highlight cell motility dynamics as a pathogenic mechanism and therapeutic target in glaucoma.
Developmental disorders
Defects in cell motility underlie various developmental anomalies, including neural tube closure defects and congenital heart disease, often linked to planar cell polarity signaling.
