核糖核酸(小干扰 RNA、微小 RNA 和信使 RNA)已成为一种有前景的新型骨再生疗法。然而,到目前为止,研究主要集中在这些寡核苷酸用于全身递送的稳定性和络合上。相比之下,从生物材料载体递送RNA纳米复合物可以促进成骨寡核苷酸的时空控制局部递送。这篇综述概述了生物材料设计的最新技术,这些材料允许对 RNA 传递进行时间和空间控制。我们将这种时空控制 RNA 递送的概念与控制骨再生的最相关事件相关联,以评估需要在多大程度上调整释放动力学。此外,受骨再生生理原理的启发,提出了潜在的新RNA靶标。最后,总结了临床转化和扩大生产的考虑因素,以刺激临床相关的 RNA 释放生物材料的设计。
Ribonucleic acids (small interfering RNA, microRNA, and messenger RNA) have been emerging as a promising new class of therapeutics for bone regeneration. So far, however, research has mostly focused on stability and complexation of these oligonucleotides for systemic delivery. By comparison, delivery of RNA nanocomplexes from biomaterial carriers can facilitate a spatiotemporally controlled local delivery of osteogenic oligonucleotides. This review provides an overview of the state-of-the-art in the design of biomaterials which allow for temporal and spatial control over RNA delivery. We correlate this concept of spatiotemporally controlled RNA delivery to the most relevant events that govern bone regeneration to evaluate to which extent tuning of release kinetics is required. In addition, inspired by the physiological principles of bone regeneration, potential new RNA targets are presented. Finally, considerations for clinical translation and upscaled production are summarized to stimulate the design of clinically relevant RNA-releasing biomaterials.
