Spinach Leaf Transformed into Beating Human Heart Tissue

This is an impressive achievement, but the headline is way off. The leaf was not transformed into 'heart tissue' and was not 'beating.'

Instead, the researchers appear to have stripped a leaf down to its cellulose structure and grown human cells on top of it to demonstrate a way of using a plant's vascular system to replace the vascular system in human tissue.

Spinach Leaf was not transformed into "beating human heart tissue", however impressive the development.
