Full-thickness burns pose a similar issue, being defined as burns that damage both the outer and inner layers of the skin. The researchers note that although the skin grafting procedure is effective, it is less applicable to large burns that cover a greater proportion of the patient’s body. By potentially eliminating the need for this procedure, 3D bioprinting could spare burn victims of the burdensome skin grafting procedure. This practical solution to burn care poses great advantages compared to the current autologous skin grafting treatment which involves the transplantation of healthy skin from other areas of the body onto the wound site. “Previously, we proved that we could deposit cells onto a burn, but there wasn’t any proof that there were any wound-healing benefits - now we’ve demonstrated that,” explained Guenther. The technology does so in a convenient manner as well, completing the process in under two minutes. This research team released the first prototype of this 3D printer in 2018 and believes that this is the first device that can generate tissue in situ. Marc Jeschke, director of the Ross Tilley Burn Centre, and his colleagues at Sunnybrook Hospital. Led by PhD candidate Richard Cheng under Professor Axel Guenther’s supervision, this project has potentially huge implications for regenerative medicine. These unique stem cells were utilized in this project to take the form of skin cells, promoting the regeneration of healthy tissue and reducing scar formation. This 3D printer’s bioink is comprised of stem cells that form specialized cell types depending on their environment, known as mesenchymal stroma cells (MSCs). This technology was developed by a research group from the University of Toronto Engineering and Sunnybrook Hospital and the successful in-vivo trials involving it were covered in the journal Biofabrication. The bioink used in this process could potentially speed up the healing process as well. Researchers have recently developed a handheld 3D printer that can print layers of skin to cover burn wounds.
