In vitro experimental study demonstrates force-driven matrix remodeling and protease-independent cancer invasion in breast cancer models, suggesting mechanical bypass routes during metastasis.

Key Points

To develop a synthetic, force-responsive 3D hydrogel platform that isolates and models the biophysical, force-driven mechanisms of cancer cell invasion independent of biochemical degradation.
Engineered a biomimetic 3D invasion platform based on cellular force-responsive polyisocyanide (PIC) hydrogels compatible with standard Transwell formats and direct optical imaging.
Formulated a constitutive mechanical model incorporating critical stress for strain stiffening to assess pericellular stiffening, force transmission, and cell-matrix interaction.
Evaluated breast cancer cell invasion and cancer-associated fibroblast (CAF) cocultures under broad-spectrum matrix metalloproteinase (MMP) inhibition compared to Matrigel.
Breast cancer cells invaded synthetic PIC networks under broad-spectrum MMP blockade, demonstrating a mechanical bypass mechanism of invasion that fails to appear in Matrigel.
Cancer-associated fibroblasts mechanically aligned and densified PIC fibers into structural tracks, significantly accelerating tumor invasion fronts.
