Spinach Leaf Transformed Into Beating Human Heart Tissue

Scientists have found a way to use spinach to build working human heart muscle, potentially solving a long-standing problem in efforts to repair damaged organs. Their study, published this month by the journal Biomaterials, offers a new way to grow a vascular system, which has been a roadblock for tissue engineering.

Scientists have already created large-scale human tissue in a lab using methods like 3D printing, but it’s been much harder to grow the small, delicate blood vessels that are vital to tissue health....
