<ul><li>Researchers at the University of Massachusetts at Amherst have measured bioelectronic signals propagating from cultured epithelial cells as they respond to a critical injury.</li><li>Epithelial cells are like ants, gathering information and solving problems collectively.</li><li>The most common hypothesis about intercell signals is the exchange of chemical cues, but this study suggests that electrical signals might also play a role.</li><li>The discovery of electrical potentials generated by wounded epithelial cells may have implications for regenerative therapies and wound healing.</li></ul>

Epithelial cells send electrical signals, possibly to communicate
