Hand-held 3D printer of sheets of skin

Engineers at the University of Toronto have built a 3D printer, using bioink, to make large skin grafts as needed in treating burns.  “The device can cover wounds with a uniform sheet of biomaterial stripe by stripe. The bioink is composed of mesenchymal stromal cells (MSCs). These stem cells differentiate into specialized cell types depending on the environment. This MSC material promotes skin regeneration and reduces scarring.”       MORE  WITH VIDEO
