A Better Artificial Skin

A patient's skin cells, genetically modified and grown in a test tube, could provide the next generation of artificial skin. As a first step in creating such replacement skin, scientists in Cincinnati have engineered bacteria-resistant skin cells in the lab and are now testing them in animals. Ultimately, they hope to produce a type of artificial skin that can sweat, tan, and fight off infection.

"We're using genetic modification to try to get the cultured skin to behave more like normal skin," says Dorothy Supp, a researcher at the Cincinnati Shriners Hospital for Children who led the project.
