“Researchers at the University of Toronto have developed a handheld 3D printer that can deposit a stem cell-loaded bioink onto wounds, such as burns, to promote tissue healing. The device acts like a paint roller, and a clinician could use it to deposit the biomaterial in even stripes on a wound surface. A recent study has shown that the deposited bioink can help tissue to heal. The researchers hope that the technique could help to heal large burns for which it is difficult to use skin grafts.
At present, skin grafts are employed to replace tissue lost in burns. However, for large burns that cover much of the body, finding enough healthy skin to cover the wounded tissue can be a challenge. “With big burns, you don’t have sufficient healthy skin available, which could lead to patient deaths,” said Marc Jeschke, a researcher involved in the project.”
