The bioengineered creation has the full thickness of natural skin and was able to speed healing and reduce scarring in animal experiments.
A team of scientists may have developed a breakthrough in wound repair: bioprinted skin that’s closer to natural skin than ever. In experiments with mice and pigs, the researchers found their skin was able to accelerate wound healing with less scarring than usual. It’s possible that this technology could one day help people completely heal from serious burns. Skin is much more complex than what we see on the surface. There are three broad layers of skin, all with their own distinct anatomy.
In this case, the team was able to create bioprinted skin using all six major types of skin cells, along with specialized hydrogels that acted as a bio-ink. The resulting mix appeared to resemble full thickness human skin, complete with all three skin layers—an apparent first, according to the researchers. Then, they tested the skin on injured mice and pigs.
