Scientists from King’s College London turned an agricultural waste product into a bone-healing scaffold; keratin from sheep’s wool produced more natural-looking regenerated bone than collagen in animals

Sheep’s wool may soon have a surprising medical purpose. Scientists at King’s College London turned wool-derived keratin into a bone regeneration scaffold. In rat skull injuries, the material helped new bone grow with a more organized structure than conventional collagen scaffolds. The finding gives regenerative medicine a sustainable biomaterial from an abundant agricultural resource. It also raises a bigger possibility: waste wool could become a useful tool for future bone repair and tissue engineering.
