Innovations like 3-D printing have enabled scientists to make significant progress in manufacturing various bioengineered organs and tissues. However, the one organ that has been hard to replicate is the human heart. That’s because current technology is unable to create the network of tiny blood vessels that transport oxygen inside a tissue as dense as the human heart muscle.
Glen Claudette, a Professor of Biomedical Engineering at the Worcester Polytechnic Institute (WPI) in Worcester, Massachusetts, was pondering over this issue with graduate student Joshua Gershlak when they came up with a brilliant idea. Instead of trying to re-create the tiny veins, why not take advantage of the similar network present in leaves to deliver water and nutrients to plant cells?
