University Of Toronto Researchers Develop Handheld 3D Skin Printer That Accelerates Healing Of Severe Burns

In case you missed it, Researchers have developed a skin printer that works like a paint roller, depositing bio ink that speeds up wound healing.

The device, developed by a team of researchers from the University of Toronto Engineering and Sunnybrook Hospital, covers wounds with a uniform sheet of biomaterial, stripe by stripe.

The bio ink dispensed by the roller is composed of mesenchymal stroma cells (MSCs) -- stem cells that differentiate into specialized cell types depending on their environment. In this case, the MSC material promotes skin regeneration and reduces scarring.

The project is led by PhD candidate Richard Cheng, under the supervision of Professor Axel Guenther, and in close collaboration with Dr. Marc Jeschke, director of the Ross Tilley Burn Centre, and his team at Sunnybrook Hospital. Their successful in-vivo trials on full-thickness wounds are reported in the journal Biofabrication.
