Cell Mechanics May Prove Vital in Cancer Behavior

Cancer cells that break away from tumors to go looking for a new home may prefer to settle into a soft bed, according to new findings from researchers at the University of Illinois.

Some particularly enterprising cancer cells can cause a cancer to spread to other organs, called metastasis, or evade treatment to resurface after a patient is thought to be in remission. The Illinois team, along with colleagues in China, found that these so-called tumor-repopulating cells may lurk quietly in stiffer cellular environments, but thrive in a softer space. The results appear in the journal Nature Communications.

“What causes relapse is not clear,” said study leader Ning Wang. Wang is the Leonard C. and Mary Lou Hoeft Professor in Engineering and professor of mechanical science and engineering of the U. of I. “Why are there a few cells left that can come back stronger? We thought cancer cells may have some properties in common with stem cells, which allows them to metastasize to different tissues. Normally, if you take a liver cell and put it in your lung, it will die. But an undifferentiated cell will live.”
