Cancer Mechanobiology
and Tumour Biomechanics
Overview of Cancer Mechanobiology
Cancer mechanobiology examines how physical forces and mechanical properties influence tumour development, progression, and treatment response. Beyond genetic and biochemical signaling, mechanical cues such as stiffness, confinement, and matrix resistance strongly regulate cancer cell behaviour.
- Changes in tumour stiffness and ECM architecture are closely linked to:
Mechanical testing provides direct, quantitative insight into how cancer cells interact with their physical environment in both in vitro disease models and engineered tumour microenvironments.
Why Mechanical Testing Is Critical in Cancer Research
Mechanical characterization enables researchers to:
- Quantify stiffness differences between healthy and malignant tissues
- Measure mechanical properties of tumor spheroids and microtissues
- Assess viscoelastic relaxation associated with tumor growth
- Evaluate mechanical confinement and compression-driven invasion
- Study stiffness-dependent drug response and mechanotherapeutic strategies
- Compare primary versus metastatic cancer cell mechanics
- Engineer tumor models with physiologically relevant stiffness
By integrating mechanical data with biological and pharmacological readouts, researchers gain a more complete understanding of tumour behaviour and therapeutic efficacy.
