骨具有内在的愈合能力,当骨折间隙太大或不稳定时,可能会超过这种能力。在那一刻,医生需要采取成骨措施。将细胞、支架和生长因子以及正确的机械条件联合收割机是重要的。生长因子在临床上作为重组蛋白给药。然而,它们是昂贵的,并且需要高的超生理剂量。此外,当施用于骨折处时,它们的半衰期很短。因此,基因治疗可能是一种替代方法。细胞可以以正确的折叠、生理糖基化和所需的量不断地产生感兴趣的蛋白质。基因可以通过病毒或非病毒方法在体内或离体递送。主要使用腺病毒。对于非病毒方法,水凝胶和最近的声致穿孔似乎是有前途的手段。本文就近年来基因治疗在骨再生方面的研究进展作一综述。
Bone has an intrinsic healing capacity that may be exceeded when the fracture gap is too big or unstable. In that moment, osteogenic measures need to be taken by physicians. It is important to combine cells, scaffolds and growth factors, and the correct mechanical conditions. Growth factors are clinically administered as recombinant proteins. They are, however, expensive and needed in high supraphysiological doses. Moreover, their half-life is short when administered to the fracture. Therefore, gene therapy may be an alternative. Cells can constantly produce the protein of interest in the correct folding, with the physiological glycosylation and in the needed amounts. Genes can be delivered in vivo or ex vivo by viral or non-viral methods. Adenovirus is mostly used. For the non-viral methods, hydrogels and recently sonoporation seem to be promising means. This review will give an overview of recent advancements in gene therapy approaches for bone regeneration strategies.
