Scientists 'herd' cells in new approach to tissue engineering

An electrical current can be used to orchestrate the flow of a group of cells, engineers have discovered. This achievement sets the stage for more controlled forms of tissue engineering and for potential applications such as 'smart bandages' that use electrical stimulation to help heal wounds. "This is the first data showing that direct current fields can be used to deliberately guide migration of a sheet of epithelial cells," said the study's lead author.
