Some interesting research. Another possible use for wool. ❤️🐑
🐑 SHEEP’S WOOL COULD HELP REPAIR DAMAGED BONES
What if a material often treated as agricultural waste could help the body rebuild damaged bone?
Scientists at King’s College London extracted keratin, a structural protein found in sheep’s wool, and turned it into membranes designed to act as bone-regeneration scaffolds. The material supported healthy bone-cell growth in laboratory tests and helped stimulate new bone formation when implanted into rats with skull defects that would not normally heal on their own.
Interestingly, collagen produced more bone overall, but the keratin-based material produced bone that was more organized, structurally secure, and had better-aligned fibers, making it more closely resemble healthy natural bone. The keratin membranes also remained stable during healing and integrated with surrounding tissue.
♻️ Because wool is renewable and can be discarded as an agricultural byproduct, researchers say it could eventually provide a more sustainable material for regenerative medicine. However, the research is still at the animal-testing stage.
🤔 Could sheep’s wool-derived keratin one day become a practical way to repair damaged bones in humans?
