What to know about Cancer Research

MIT engineers have discovered that epithelial cells synchronize and pulse collectively during migration, with malignant cancer cells exhibiting more persistent synchronization than healthy cells. The researchers suggest this rhythmic behavior could potentially serve as a clinical signal for tumor aggressiveness or a method for screening drug effectiveness.

What happened

Cells pulse together as they grow—and malignant cells pulse the longest Gaby Clark Scientific Editor Robert Egan Senior Editor Epithelial cells are the tiny shields that line and protect our bodies.

Why it matters

In a developing embryo, epithelial cells grow, divide and move into positions to form the outer layers of our skin and the surfaces of our organs and blood vessels.

Common ground

When we scrape our skin, suffer an internal tear or undergo surgery, epithelial cells migrate to the site of injury to heal a wound.

Claim 8: “The researchers also observed a correlation between cell synchronization and cell density: In each dish of cells, regardless of type, the cells continued to grow, divide and pulse.
