Researchers identify how cells move faster through mucus than blood

Researchers have discovered that certain cells move surprisingly faster in thicker fluid because their ruffled edges sense the viscosity of their environment and adapt to increase their speed. Their combined results in cancer and fibroblast cells suggest that the viscosity of a cell’s surrounding environment is an important contributor to disease, and may help explain tumor progression, scarring in mucus-filled lungs affected by cystic fibrosis, and the wound-healing process.
