How it's made: First, a custom bioprinter scans and maps the patient's wound. One inkjet valve ejects the enzyme thrombin, and another ejects cells mixed with collagen and fibrinogen (thrombin and fibrinogen react to create the blood coagulant fibrin). Then, the printer deposits a layer of human fibroblasts, followed by a layer of skin cells called keratinocytes.
Benefit: For traditional grafts, surgeons take skin from one area of the body and splice it onto another. The Wake Forest researchers hope to print new skin directly into a wound. Ultimately, they plan to build a portable printer that can be used in war and disaster zones.
