Researchers at King's College London have developed a novel method to regenerate damaged bone using keratin extracted from sheep's wool. This natural protein, when tested in animal models, demonstrated superior structural organization and alignment compared to conventional collagen scaffolds. The study revealed that keratin-based membranes supported more effective bone regeneration, producing tissue closer to healthy bone structure. Key advantages include sustainability, as wool is an agricultural byproduct often discarded as waste, and durability, with the material remaining stable during healing. Unlike traditional collagen scaffolds, which degrade too quickly for weight-bearing repairs, keratin provides a renewable resource that could revolutionize regenerative medicine. The findings, published in ScienceDaily, mark a significant milestone in biomaterials research, positioning keratin as a potential alternative to collagen in medical applications. This innovation addresses limitations of current materials while offering scalable and eco-friendly solutions for bone repair.
