A group of researchers at Worcester Polytechnic Institute (WPI) were able to create functional, beating heart tissue out of spinach leaves.
Scientists stripped away the plant cells from a spinach leaf to maintain only its cellulose frame, which was then injected with human cells. The intricate and fragile vascular networks on spinach leaves are similar to those in human organs.
Within a few days, the tissue grew and scientists were able to pump fluids through the veins of the structure to simulate human blood vessels. Make sure to watch a video of the spinach organ.
