Researchers at UC Berkeley have managed to use an electric field to herd a flock of epithelial cells — a trick called galvanotaxis. It’s a very blunt tool at the moment, but scientists hope it can be refined and used to help wounds heal.
An exciting step in the direction of “smart bandages” — using an electrical stimulation to help heal wounds. The researchers used the same cells that bind together to form skin, kidneys and other organs.
