Why in news
Scientists at King's College London developed an experimental bone-healing material derived from sheep wool keratin as a sustainable alternative to collagen.
Background
The research focuses on keratin, a structural protein found in wool, hair, and nails. Laboratory and animal tests confirmed the material supports bone regeneration and produces tissue resembling healthy natural bone.
Facts for Prelims
- S&TKeratin: A structural protein found in wool, hair, and nails used in the new bone-healing material.
- FactThe wool-derived material was tested in laboratory and animal trials to support bone regeneration.
- S&TThe material serves as a sustainable alternative to conventional collagen-based scaffolds for bone repair.
For Mains
Q. Discuss how the development of sustainable biomaterials from animal by-products can address the limitations of conventional synthetic scaffolds in regenerative medicine.
Dimensions to cover in your answer
- Resource efficiency: Utilizing keratin from wool as a sustainable alternative to collagen-based scaffolds
- Biocompatibility: Superiority of wool-derived material in mimicking natural bone tissue structure
- Clinical scalability: Transitioning from animal models to human trials for dental and orthopedic reconstruction
