If an overhyped vegetable existed before marketers coined the term superfood – and long before Oprah Winfrey chatted up acai berries with Dr. Oz – look no further than spinach.

A team of US scientists has found a way to use the veins of the leaf of a spinach to make a miniature version of the beating heart muscle. Their discovery provides a potential solution to the major challenges faced by biomedical engineers: how to repair and regenerate damaged organs and tissues.

If it works, scientists could use this discovery to treat patients who have suffered a heart attack, said the scientists in the survey, which was published this month in the journal “Biomaterials”. The existing biomechanical techniques, including 3D printing, can not create a branching network of blood vessels stretching to the capillaries.

“This small machine is crucial in the supply of oxygen and nutrients needed by the tissue molecules for proper growth,” says Joshua Gershlak, co-author of the study and a graduate student at Worcester Polytechnic Institute in Massachusetts.

The main limiting factor in tissue engineering is the lack of vascular network – without it, you are getting a dead tissue, he added.

In the series of experiments, the scientists took a spinach leaf,  cleaned the veins to remove the plant’s cells. Then they released fluid and tiny granules, who represented human, through the venous network of the spinach leaf. It resulted in tissue that mimics a heartbeat and was full of veins and arteries. However, testing on humans is still very distant.

“We still have a lot of work, but this is now quite promising,” said Glenn Gaudet, professor of biomedical engineering at Worcester Polytechnic Institute.
