Spinach might be good for your heart, but scientists at Worcester Polytechnic Institute are actually trying to turn spinach into heart tissue. Using a process that strips the cells from plants, researchers turned the leafy green into a clear cellulose structure that happens to have a similar structure to human blood vessels. Researchers believe that once they attach the plant structure to a blood source, the body might be able to use that to create new tissue around it, repairing damage from injury or disease.
