Regenerative medicine in situ: a handheld 3D bio-printer for deep skin wound healing

Researchers develop a handheld 3D printer, depositing strips of skin tissue and crosslinked proteins to help aid the bodies repair process. Researchers from the University of Toronto (ON, Canada), led by Professor of Applied Science and Engineering, Axel Guenther (University of Toronto) have developed a light, handheld printer for deep skin wounds. The study, published in Lab on a Chip, describes the printer appling layers of a bioink containing skin tissue, cross linked biomaterials and proteins, to aid skin healing, depositing and fixing in under 2 minutes. Requiring little training, the team hopes their device could bridge the gap between...
