Wound dressing sheet developed from human protein

Gulf Today Report

Scientists at Germany's Fraunhofer Institute, Martin Luther University and biotechnology company “Skinnomics” developed a dressing for chronic wounds from the human protein known as “tropolastin” which turns into elastin in the body, and gives skin and some human organs their elastic properties.

Elastin is a protein located in elastic connective tissues and allows many tissues in the body to regain their shape after being stretched or damaged.

In the past, scientists injected tropolastin directly into wounds, but it did not give the desired results.

The new dressing is a treatment for complex wound diseases such as venous ulcers, leg ulcers or foot ulcers, and it is long-lasting and does not cause damage to the bones.

Scientists used an electrospinning process to produce ultra-thin tropolastin nanofibres, which were bonded together to form a sheet of an elastin-like material. According to scientists, the new wound dressing combines biocompatibility, durability, biodegradability and favourable mechanical properties similar to those of the skin.
