Summary
Research published in Science Advances (2020) demonstrated that more aggressive cancer cells are more deformable, enabling invasion through tissues. 3D Petri Dish® spheroids provided the invasion models for this mechanical analysis.
Cancer Aggressiveness Correlates with Cell Deformability
Research Overview
Cancer metastasis requires cells to squeeze through tight spaces. This study reveals that cellular deformability directly correlates with invasive potential and clinical aggressiveness.

Frequently Asked Questions
How does cell deformability affect cancer spread?
More deformable cells can squeeze through blood vessel walls and tissue barriers more easily, enabling metastasis to distant organs.
Can mechanical properties predict cancer aggressiveness?
Yes, this research shows strong correlation between cellular deformability and clinical aggressiveness, suggesting potential diagnostic applications.
Why are spheroids better than 2D cultures for invasion studies?
Spheroids have proper cell-cell junctions and can be embedded in matrix for realistic 3D invasion assays that mimic tumor spreading.
