New study shows that aggressive cancer cells can be detected in a simple, new way. by how they behave physically, not just by their genes. Using specially textured Meta surfaces with tiny immobilized particles, the researchers found that aggressive cancer cells grip harder, swallow more particles, and change shape in ways that less aggressive cells don’t, differences that standard flat lab tests completely miss. This matters because it offers a rapid, label-free and potentially low-cost method for distinguishing aggressive cancer cells, improves our understanding of how cancer spreads, and opens the door to new diagnostic and research tools that could better predict which cancers are more likely to metastasize.
A new study reveals a simple and fast, label-free way to distinguish aggressive cancer cells from their natural behavior. Researchers at the Hebrew University of Jerusalem have developed a new way to identify aggressive cancer cells, not by analyzing their genes or chemical markers, but by observing how they naturally interact with their environment.
The research, published in Materials Today Biowas directed by Ph.D. Student Chalom Zemmour under the guidance of Prof. Ofra Benny from the Hebrew University School of Pharmacy. It introduces a new technology that uses specially designed, microscopically patterned surfaces to act as a kind of “mechanical sensor” for cancer aggressiveness.
Watching cancer cells reveal their true nature
Cancer cells are typically classified using molecular and genetic tests. While powerful, these methods can be expensive, time-consuming, and sometimes fail to capture how dangerous a cell really is. Aggressive cancer cells, those that can spread to other organs, often look like less harmful cells under standard laboratory conditions.
The new method takes a different approach.
Instead of asking what molecules cancer cells express, the researchers asked: how do cancer cells physically behave when they interact with their environment?
To answer this, the team created special surfaces patterned with tiny plastic beads that create nano and micro topographies. thousands of times smaller than a grain of sand, forming a relief landscape invisible to the naked eye. When cancer cells are placed on these surfaces, their behavior changes depending on how aggressive they are.
More aggressive cancer cells:
- Grip the surface harder
- Swallow more of the tiny particles
- Stretch and wrap themselves around tiny features
Less aggressive cells behave very differently—even though these differences are undetectable on ordinary flat lab surfaces.
A new window on metastasis
The study also revealed something unexpected about metastasis, the process by which cancer spreads.
The researchers found that the special surfaces could differentiate cells with different metastatic stages as occurs in the body, where cancer cells temporarily lose their ability to adhere strongly after leaving the primary tumor, possibly helping them travel through the body. Once they reach a new location, however, they regain strong adhesion and mechanical activity.
“This tells us that this aggression is not a fixed trait and we can have a sensitive technology to measure it,” explains Professor Benny. “It’s a functional state that can be revealed through physical behavior, not just molecular signatures.”
Simple, accessible and potentially clinical
One of the major advantages of the new method is its simplicity. It does not require dyes, tags or complex genetic analysis. The surfaces can be produced using standard laboratory techniques and are compatible with imaging and molecular assays already in use in research and clinical laboratories.
Because of this, the technology could eventually be adapted for:
- Rapid control of cancer cell aggressiveness
- Tumor metastasis and progression research
- Drug trials and personalized cancer treatment
Rethinking how we recognize dangerous cancer
The study highlights a growing shift in cancer research – beyond purely molecular analysis towards the functional and mechanical characteristics of cells.
“Our work shows that how cancer cells push, pull and grip their environment can tell us a lot about how dangerous they are,” says Professor Benny. “This opens up a new avenue for cancer diagnosis that is both powerful and surprisingly simple.”
