A team of researchers from several American universities have authored a study that could eventually see spinach used in heart surgery.
Previous work demonstrated how human tissue can be reproduced with 3D printing, but the replication tiny blood vessels proved difficult. The new study shows that spinach leaves, with their fine veins to transport water and nutrients, could be modified by removing plant cells and introducing human cells, which would then grow around the network of veins to transport blood cells.
In other words, for those with cardiac muscle tissue damage, new heart tissue could be generated from plants and converted for use as replacement blood vessels. It represents the first step toward “a new branch of science that investigates the mimicry between kingdoms”.
