Physical Behavior Unlocks New Method to Identify Aggressive Cancer Cells

Israeli researchers at the Hebrew University of Jerusalem have developed a novel method to identify aggressive cancer cells based on their physical behavior. This innovative approach aims to improve detection, as aggressive cancer cells capable of spreading often appear similar to less harmful cells in standard lab conditions.

A Novel Approach to Cell Analysis

Unlike traditional tests that analyze genes or chemical markers, the new method observes how cancer cells adhere to and engulf particles on specially designed microscopic surfaces. These surfaces are intricately patterned with tiny beads, ranging from 0.23 to 2.3 micrometers, strategically placed at different densities.

Unveiling Distinct Cancer Cell Behaviors

Researchers tested various cancer cell types, with results published in Materials Today Bio, revealing distinct and telling behaviors.

At metastatic sites, where cancer spreads, cells demonstrated a clear propensity to grab more beads, cling tighter to the surfaces, and extend actin-rich 'arms' to wrap around the particles.

Interestingly, observations also captured a dynamic change in cells traveling through the lymph after leaving the main tumor. These cells exhibited reduced stickiness but an increased bead ingestion, suggesting a temporary loss of adhesion during transit and a subsequent regain of stickiness once they reach new sites.

Promising Applications for Future Cancer Care

The researchers indicated that this new method offers significant advantages, as it does not require dyes or labels. This could make it broadly applicable for rapid screening, in-depth studies of cancer spread mechanisms, more efficient drug testing, and the development of personalized treatment strategies.
