Melanoma, a deadly form of skin cancer, is notorious for its ability to switch between growing and spreading – a phenomenon known as phenotypic plasticity. For decades, scientists have suspected that cues from the tumor’s surroundings trigger this switch, but the exact mechanism remains a mystery. Without tools that mimic the physical pressures tumors experience in the body, it was challenging to study how mechanical forces influence cancer behavior. This gap limited our understanding of how harmless skin cancers turn invasive and drug-resistant.




In this study, researchers utilized the VitroGel® Cell Invasion Assay Kit to simulate the tight spaces that melanoma cells encounter during their invasion of surrounding tissues. By confining cells within a tunable hydrogel matrix, the team discovered that physical pressure triggers a dramatic reprogramming of the cells, shifting them from a proliferative state to an invasive one. The VitroGel® system enabled precise control over mechanical stress, revealing that confined cells activate a protein called HMGB2, which remodels chromatin and promotes genes associated with invasion and drug tolerance. This hydrogel-based approach was crucial for mimicking the in vivo microenvironment and elucidating the molecular link between force and cancer aggressiveness.
This study demonstrates that mechanical confinement is a key factor in driving melanoma progression. The use of the VitroGel® Cell Invasion Assay Kit was instrumental in bridging the gap between cell culture and real-world tumor behavior, providing a physiologically relevant platform for studying invasion. By enabling researchers to replicate the mechanical forces tumors experience in the body, VitroGel® opens new avenues for studying cancer plasticity, screening anti-invasion drugs, and developing personalized treatment strategies.
