Wool Keratin Scaffolds Outperform Collagen in Bone Regeneration

5/21/2026

Summary

Story summary

The study positions wool-derived keratin as a renewable scaffold that could replace collagen in bone-regeneration procedures.
Researchers at King's College London implanted keratin membranes into rats with skull defects, observing successful bone regeneration.
Laboratory tests showed the keratin scaffolds supported healthy growth of human bone cells.
Compared with collagen, the keratin membranes produced more organized, structurally stable bone that integrated smoothly with surrounding tissue throughout healing.
