The physical texture of a cancer cell's surface is enough to trick healthy cells into acting like part of the tumor.

The Takeaway
We usually blame chemicals for cancer spread, but this proves 'shape' alone is a powerful signal. Healthy stem cells change their behavior and density just by touching the jagged, mimetic surface of a breast cancer cell.
From the abstract
Mesenchymal stem cells (MSCs) are studied for regenerative applications, yet in tumour contexts they may adopt environment-dependent behaviours that influence stromal remodelling. The tumour microenvironment provides biochemical and biophysical cues that regulate stromal cell state, but the contribution of tumour-specific surface topography remains poorly defined. Here, we investigated whether breast epithelial/cancer cell–derived micro- and nano-topography modulates MSC behaviour. Membrane topo
