Research on the capability of non-viral gene delivery systems to induce tissue regeneration is a continued effort as the current use of viral vectors can present with significant limitations. Despite initially showing lower gene transfection and gene expression efficiencies, non-viral delivery methods continue to be optimized to match that of their viral counterparts. Ultrasound-mediated gene transfer, referred to as sonoporation, occurs by the induction of transient membrane permeabilization and has been found to significantly increase the uptake and expression of DNA in cells across many organ systems. In addition, it offers a more favorable safety profile compared to other non-viral delivery methods. Studies have shown that microbubble-enhanced sonoporation can elicit significant tissue regeneration in both ectopic and disease models, including bone and vascular tissue regeneration. Despite this, no clinical trials on the use of sonoporation for tissue regeneration have been conducted, although current clinical trials using sonoporation for other indications suggest that the method is safe for use in the clinical setting. In this review, we describe the pre-clinical studies conducted thus far on the use of sonoporation for tissue regeneration. Further, the various techniques used to increase the effectiveness and duration of sonoporation-induced gene transfer, as well as the obstacles that may be currently hindering clinical translation, are explored.
由于目前使用病毒载体存在显著局限性,因此对非病毒基因递送系统诱导组织再生能力的研究一直在持续进行。尽管非病毒递送方法最初显示出较低的基因转染和基因表达效率,但仍在不断优化以使其与病毒递送方法相匹配。超声介导的基因转移,即声孔效应,是通过诱导瞬时膜通透性实现的,并且已发现在许多器官系统的细胞中,它能显著增加DNA的摄取和表达。此外,与其他非病毒递送方法相比,它具有更良好的安全性。研究表明,微泡增强声孔效应在异位和疾病模型中,包括骨和血管组织再生中,都能引发显著的组织再生。尽管如此,目前尚未进行关于使用声孔效应进行组织再生的临床试验,不过目前使用声孔效应治疗其他适应症的临床试验表明该方法在临床环境中使用是安全的。在这篇综述中,我们描述了迄今为止关于使用声孔效应进行组织再生的临床前研究。此外,还探讨了用于提高声孔效应诱导基因转移的有效性和持续时间的各种技术,以及目前可能阻碍临床转化的障碍。
