Cells Lining Organs Can Generate Electricity When Injured, Offering New Wound Treatment Possibilities

Your cells constantly generate and conduct electricity that runs through your body to perform various functions. One such example of this bioelectricity is the nerve signals that power thoughts in your brain. Others include the cardiac signals that control the beating of your heart, along with other signals that tell your muscles to contract.

As bioengineers, we became interested in the epithelial cells that make up human skin and the outer layer of people’s intestinal tissues. These cells aren’t known to be able to generate bioelectricity. Textbooks state that they primarily act as a barrier against pathogens and poisons; epithelial cells are thought to do their jobs passively, like how plastic wrapping protects food against spoilage.

To our surprise, however, we found that wounded epithelial cells can propagate electrical signals across dozens of cells that persist for several hours. In this newly published research, we were able to show that even epithelial cells use bioelectricity to coordinate with their neighbors when the emergency of an injury demands it. Understanding this unexpected twist in how the body operates may lead to improved treatments for wounds.
