A new device that reprograms skin cells could represent a breakthrough in repairing injured or ageing tissue. The new technique, called tissue nanotransfection, is based on a tiny device that sits on the surface of living skin. An intense, focused electric field is applied to the device, allowing it to deliver genes to the skin cells beneath it, turning them into different types of cells.

This is an exciting opportunity when it comes to repairing damaged tissue - turning a patient's own tissue into a bioreactor to produce cells to either repair nearby tissues, or for use at another site. https://www.theguardian.com/science/2017/aug/07/nanochip-could-heal-injuries-or-regrow-organs-with-one-touch-say-researchers
