Scientists have created a synthetic-organic substitute for human skin
A group of researchers from the U.S. Baltimore said the development of a new composite material, which in the future may replace the damaged soft tissue. The liquid material consisting of a composite of biological and synthetic molecules, is injected under the skin, then "set" using light radiation to give the desired shape and a more solid structure, the statement of the Institute of Medical Research at Johns Hopkins.
One of the most likely ways in which the material is a facial reconstruction and replacement of the skin affected during or injury from burns. According to the researchers, the composite nature of the material helps the body to take it easier. "Implanted biological materials can mimic the structure of the soft tissues, but usually they are broken down by the body very quickly, while synthetic materials are more durable, although they may be rejected by the immune system because they are ill of the natural tissue, "- said the head of research Jennifer Elisseeff.
"Our composite material combines the best aspects of both worlds." element consists of hyaluronic acid - a natural component of the skin that gives it elasticity, and polyethylene glycol - a synthetic molecule used as a surgical adhesive that does not cause severe immune reactions. U.S. researchers say that their material is promising, but a number of difficulties does not allow them to carry out full-fledged clinical trials.
"We still have to evaluate the durability and safety of our material in other types of human tissues, such as muscles, less fatty regions under the skin of the face. Perhaps in the future we will need to optimize it for specific procedures," - she said.
