Nat Commun:具有通道样孔结构的生物材料可有效诱导骨缺损的软骨内愈合

2018-11-01 MedSci MedSci原创

开发用于治疗骨缺损的生物材料通过直接的膜内骨化以用于骨愈合。相比之下,我们体内的大部分骨骼都是通过软骨模板通过称为软骨内骨化的第二条路径发展而来。再生大骨缺损的未解决的临床挑战已经将软骨内骨化作为骨愈合的替代方法进行讨论。然而,缺少通过软骨内骨化再生大骨缺损的生物材料策略。 本研究中,研究人员报告了一种具有通道样孔结构的生物材料,以控制愈合早期阶段的细胞募集和组织模式。由于细胞外基质排列,C

开发用于治疗骨缺损的生物材料通过直接的膜内骨化以用于骨愈合。相比之下,我们体内的大部分骨骼都是通过软骨模板通过称为软骨内骨化的第二条路径发展而来。再生大骨缺损的未解决的临床挑战已经将软骨内骨化作为骨愈合的替代方法进行讨论。然而,缺少通过软骨内骨化再生大骨缺损的生物材料策略。

本研究中,研究人员报告了一种具有通道样孔结构的生物材料,以控制愈合早期阶段的细胞募集和组织模式。由于细胞外基质排列,CD146 +祖细胞积聚和抑制血管形成,在大鼠中诱导高度组织的软骨内骨化过程。

综上所述,该研究结果表明,纯生物材料方法有可能概括骨骼愈合的发育骨生长过程。这可能会激发未来基于生物材料的组织再生策略。
