Bioprinting complex living tissue in just a few seconds

Posted by in categories: bioprinting, biotech/medical, engineering

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

Researchers at the Laboratory of Applied Photonics Devices (LAPD), in EPFL’s School of Engineering, working with colleagues from Utrecht University, have come up with an that takes just a few seconds to sculpt complex shapes in a biocompatible hydrogel containing stem . The resulting tissue can then be vascularized by adding endothelial cells.

The team describes this high-resolution printing method in an article appearing in Advanced Materials. The technique will change the way cellular engineering specialists work, allowing them to create a new breed of personalized, functional bioprinted organs.
