A research team headed by Worcester Polytechnic Institute (WPI) scientists* has solved a major tissue engineering problem holding back the regeneration of damaged human tissues and organs: how to grow small, delicate blood vessels, which are beyond the capabilities of 3D printing.**

The researchers used plant leaves as scaffolds (structures) in an attempt to create the branching network of blood vessels — down to the capillary scale — required to deliver the oxygen, nutrients, and essential molecules required for proper tissue growth.

In a series of unconventional experiments, the team cultured beating human heart cells on spinach leaves that were stripped of plant cells.
