What does this research mean for the field?

A novel fragmented gelatin methacryloyl (GelMA) scaffold that decouples stiffness from porosity demonstrates that adherent-to-suspension transition (AST) enables non-metastatic breast cancer cells to migrate within interstitial spaces, particularly in stiffer environments. Novelty: ClaimNovelty.METHODOLOGICAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

In vitro study demonstrates porous GelMA hydrogels drive cancer cell migration via adherent-to-suspension transition, highlighting matrix porosity in metastasis.

Key Points

To develop a fragmented gelatin methacryloyl (GelMA) scaffold that independently controls matrix stiffness and porosity to evaluate cellular plasticity and migration during cancer metastasis.
Engineered fragmented granular GelMA scaffolds capable of decoupling hydrogel stiffness from micro-scale interstitial porosity.
Encapsulated non-metastatic and metastatic breast cancer cells as single cells to measure proliferation, mechanosensitive migration, and velocity under adherent-to-suspension transition (AST).
Assessed molecular markers of cellular detachment and nuclear stability, specifically Lamin A/C and nuclear yes-associated protein (YAP).
Metastatic breast cancer cells exhibited altered mechanosensitivity and significantly enhanced migration within the fragmented scaffold compared to non-metastatic cells (p < 0.05).
Non-metastatic cells underwent AST-dependent interstitial migration that was significantly enhanced in stiff scaffolds (p < 0.05), reaching velocities similar to invasive metastatic cells.
Induction of AST significantly increased structural Lamin A/C levels and reduced nuclear YAP localization in migrating cells.
