Global Technology – September 2019

Artificial organs and tissues can be used to develop and test new drugs, repair damaged tissue and even replace entire organs in the human body.  Unfortunately, current fabrication methods limit the ability of tissue engineers to produce free-form shapes and achieve high cell viability.

But now, French researchers, have come up with an optical technique that takes just a few seconds to sculpt complex tissue shapes in a biocompatible hydrogel containing stem cells.  The resulting tissue can then be vascularized by adding endothelial cel.....
