Skeletal regenerative medicine emerged as a field of investigation to address large osseous deficiencies secondary to congenital, traumatic, and post-oncologic conditions. Although autologous bone grafts have been the gold standard for reconstruction of skeletal defects, donor site morbidity remains a significant limitation. To address these limitations, contemporary bone tissue engineering research aims to target delivery of osteogenic cells and growth factors in a defined three dimensional space using scaffolding material. Using bone as a template, biomimetic strategies in scaffold engineering unite organic and inorganic components in an optimal configuration to both support osteoinduction as well as osteoconduction. This article reviews the various structural and functional considerations behind the development of effective biomimetic scaffolds for osteogenesis and highlights strategies for enhancing osteogenesis.
骨骼再生医学作为一个研究领域应运而生,旨在解决先天性、创伤性和肿瘤后疾病导致的大骨缺损问题。尽管自体骨移植一直是骨骼缺损重建的金标准,但供区并发症仍然是一个重大限制。为了解决这些限制,当代骨组织工程研究旨在利用支架材料在确定的三维空间中靶向递送成骨细胞和生长因子。以骨为模板,支架工程中的仿生策略将有机和无机成分以最佳配置结合起来,以支持骨诱导和成骨传导。本文综述了有效仿生骨生成支架开发背后的各种结构和功能考量,并强调了增强骨生成的策略。
