伦敦国王学院的科学家成功从羊毛中提取角蛋白，用于促进受损骨骼的再生1。在大鼠颅骨缺损模型的动物试验中，角蛋白支架产生的新骨组织比传统胶原蛋白支架更具组织性，纤维排列更加规则，其结构也更接近健康骨骼1。
该研究还发现，角蛋白膜在愈合过程中保持稳定，能够与周围组织平滑整合1。研究团队认为这一成果具有重要意义，Dr. Sherif Elsharkawy表示："这将角蛋白定位为可能挑战长期依赖胶原蛋白的新型再生生物材料"1。由于羊毛是农业中常见的废弃物，具有可再生和可扩展的潜力，这项研究有望将农业副产品转化为再生医学的新型材料1。
Researchers at King's College London have discovered that keratin extracted from sheep's wool can effectively stimulate the regrowth of damaged bone tissue.1 In animal trials using a rat skull defect model, keratin scaffolds produced new bone tissue that was more organized and had better fiber alignment compared to traditional collagen scaffolds.1 The keratin membrane remained stable throughout the healing process and integrated smoothly with surrounding tissue.1
This breakthrough transforms an agricultural byproduct into a promising regenerative medicine material.1 According to Dr. Sherif Elsharkawy, the findings position "keratin as a possible material to challenge the long-term reliance on collagen in regenerative biomaterials."1 Since wool is a common agricultural waste with renewable and scalable potential, the development could open new avenues for utilizing agricultural byproducts in medical applications.1
