3d printed skin for burn victims9/16/2023 ![]() ![]() It heals differently enough that additional animal studies will be required before we start trying it on humans. SkinPrint: 3D Bio-printed human skin can help burn victims, May 16. “The entire surgery took about 10 minutes.” Don't get too excited, mouse skin is not people skin. Raelin, Wake Forest 3D Prints Skin Cells Onto Burn Wounds, Jul. “It was like putting a pair of shorts on the mice,” Abaci said. Initial lab tests with mouse models were encouraging. As with making flat sheets, the entire process requires around three weeks for the cells to fully set up and be ready for transplant. It's coated with skin fibroblasts and collagen then covered by an outer layer of keratinocytes (which make up the epidermis) and growth medium to feed the cells as they mature. This serves as the scaffolding on which the patient's cultured cells will grow. That data is worked through a CAD program to generate a hollow wireframe of the appendige and then printed. Institute scientists are working on a way to print skin cells on burn wounds that traditional healthy-skin harvesting techniques may not be able to support. The transplant site is first scanned with a 3D laser to create a digital facsimile of the structure. The process of making these skin prosthetics isn't that far off from the existing techniques which result in flat slabs of skin. The Columbia team has dubbed the grafts "wearable edgeless skin constructs" (WESCs). What's more, these uniform grafts have shown superior performance, both mechanically and functionally, than their patchwork alternatives. ![]() “They would dramatically minimize the need for suturing, reduce the length of surgeries, and improve aesthetic outcomes.” Hasan Erbil Abaci, lead researcher and assistant professor of dermatology at Columbia University, said in a recent press release. “Three-dimensional skin constructs that can be transplanted as ‘biological clothing’ would have many advantages,” Dr. They explained how they engineered, "the skin as a fully enclosed 3D tissue that can be shaped after a body part and seamlessly transplanted as a biological clothing." The team published their findings, " Engineering edgeless human skin with enhanced biomechanical properties," in the January issue of Scientific Advances.
