King's College London Tests Wool Keratin in Rats, Advancing Bone Repair Beyond Collagen

Wool-derived keratin membranes repaired skull defects in rats, generating organized, stable bone tissue in the first in-vivo test reported by King’s College London researchers.
Lab and animal results suggest keratin could address collagen’s weaknesses: the wool-based scaffold stayed stable during healing, integrated with surrounding tissue and guided bone growth across defects that would not heal on their own.
Collagen still produced a greater overall volume of bone, but the keratin scaffolds yielded better-aligned fibers and bone architecture that more closely resembled healthy natural bone.
The study positions keratin as a potential regenerative-medicine and dental alternative that is also renewable and scalable, since wool is naturally sourced and often discarded as farm waste.
Can a simple farm byproduct dethrone the gold standard material used in modern bone surgery?
Is using a common allergen like wool to rebuild our skeletons a breakthrough or a hidden risk?
Keratin builds better bone, but collagen builds more. Which is the real key to human healing?
King's College London Develops Wool Keratin Bone Repair Material with Superior Performance and Sustainability
Overview
King's College London researchers have developed a novel bone repair material made from wool keratin, aiming to provide a sustainable and effective alternative to traditional bone repair methods. This new material has shown strong results in animal models, successfully supporting bone regeneration within living systems. The breakthrough brings the technology much closer to real patient use and marks a crucial step toward clinical application. Driven by the need for sustainable and readily available biomaterials, the wool keratin approach highlights the potential of using natural resources to advance regenerative medicine and improve patient outcomes.
