Scientists convert leaves into human heart tissue


In a startling experiment, scientists have managed to successfully turn spinach leaves into working heart tissue – complete with veins and blood vessels.

Researchers from Worcestor Polytechnic Institute [WPI] used the leaf’s own network of veins to develop a network of cells that supports human functions by first stripping the plant off green material until the only thing left was fine cellulose structure holding the leaf in one place.

The leaf’s vascular structure was seeded with heart muscle cells and after a few days of wait, the heart cells suddenly contracted mirroring the movement of a human tissue.
