Technology Review: Growing Organs and Helping Wounds Heal: "A stretchy new fabric made by linking together the proteins found in muscle tissue could provide a scaffold for growing new organs. It could also be used as a coating for bandages to help wounds heal quickly and with less scarring. The fabric was made in the laboratory of Kevin Kit Parker, a professor at Harvard's School of Engineering and Applied Science. When the body grows new tissue, cells secrete fibronectin--a strong, stretchy type of protein that acts as a supportive scaffold. The shape and structure that fibronectin adopts directs the subsequent growth of new cells, giving the resulting tissue the correct form."
