This article, written by Saman Naghieh , University of Saskatchewan , originally appeared on The Conversation and has been republished here with permission: Due to the global organ shortage and limited organ donors, thousands of patients are left wanting organs and tissues in cases of severe injuries, illness or genetic conditions.

 .

Many of these patients die before transplants are available. Tissue engineering is an emerging field that works on producing artificial tissue and organ substitutes as permanent solutions to replace or repair damage. As biomedical engineering researchers, we are developing 3D temporary organ structures — called scaffolds — that may help regenerate damaged tissues and potentially lead to creating artificial organs. These tissues can also be used in various tissue engineering applications, including nerve repair in structures constructed from biomaterials. Printing tissue Approximately 22.6 million patients require neurosurgical interventions annually around the world to treat damage to the peripheral nervous system. This damage is primarily caused by traumatic events such as motor vehicle accidents, violence, workplace injuries or difficult births. It is anticipated that the cost of global nerve repair and regeneration will reach […]
