If you’re trying to make a wound dressing that will be well-tolerated by the human body, you may be best off using human-derived materials. That’s the approach that German researchers have taken, creating a tropoelastin-based bandage. Tropoelastin protein molecules are produced naturally by the human body, and they’re the main building block of elastin, a biopolymer which gives the skin and organs their elastic properties. In the past, scientists have tried to reduce scarring by injecting tropoelastin directly into wounds, without much success … read more
