Cells lining your skin and organs can generate electricity when injured − potentially opening new doors to treating wounds
Textbooks usually depict the epithelial cells encasing the interior and exterior of your body as passive barriers. But researchers discovered they can produce electrical signals like neurons.
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. These findings suggest that while calcium ions may play a particularly crucial role in allowing epithelial cells to produce bioelectricity, other molecules may also matter.
