Vegetables are good for your health, but now there's a whole new way that one veggie could help your heart: Spinach leaves can be used as a scaffold for beating human heart cells, a new study finds.

In several experiments, scientists grew beating human heart cells on spinach leaves by perfusing them with a detergent solution, which stripped them of their plant cells. This proof-of-concept study suggests that multiple spinach leaves could be used to grow layers of healthy heart muscle that could one day be used to treat heart attack patients, the researchers said.

"We have a lot more work to do, but so far this is very promising,” Glenn Gaudette, the study's senior researcher and a professor of biomedical engineering at the Worcester Polytechnic Institute (WPI) in Worcester, Massachusetts, said in a statement. "Adapting abundant plants that farmers have been cultivating for thousands of years for use in tissue engineering could solve a host of problems limiting the field."
