"With a chronic shortage of donor organs, researchers have resorted to engineering large-scale human tissue using techniques such as 3-D printing. One complex problem that has impeded this research, however, is how to recreate a small, intricate vascular system in order to deliver oxygen and nutrients required for proper tissue growth.
“One of the big problems in tissue engineering today is getting blood supply to the newly-created tissue,” Gaudette explained to CTVNews.ca in a phone interview from Worcester, Mass.
To overcome this problem, scientists have started looking at plants for a potential solution. Bioengineering researchers have begun experimenting with growing organs on different plants using their branching network of veins, which delivers water and nutrients to the leaves."
