Scientists turn Spinach into Human Heart Tissue

</p> <h2>Scientists turn spinach into human heart tissue</h2> <p> Popeye was right: spinach really is good for the muscles, and not just the ones in your biceps. In fact, scientists have discovered a way to use the leafy stuff, which has a vascular system not dissimilar to ours, to grow layers of working heart muscle, according to a paper published this month in the journal Biomaterials. The new technique, a collaboration between Worcester Polytechnic Institute, the University of Wisconsin-Madison, and Arkansas State University-Jonesboro, marks a breakthrough in the field of human tissue regeneration, which has hitherto been stymied by scale. To wit, although current bioengineering methods can recreate cellular scaffolding on a large scope, fabricating branching networks of tiny blood vessels has proven far trickier.</p> <p>
