用于组织修复的支架必须提供结构和生化线索,以启动导致适当组织形成的复杂级联事件。将基因插入这些支架中是蛋白质递送的有吸引力的替代方案,因为基因递送可以对任何DNA序列进行调节,并且基因利用细胞的机制来连续产生治疗性蛋白质,从而导致更持久的转基因表达和自分泌和旁分泌信号传导的激活,而这些信号传导在大量蛋白质递送时不会被激活。在这篇综述中,我们讨论了支架设计的重要性及其设计参数(例如材料、结构、载体掺入、生化线索呈现)对转基因表达和组织修复的影响。
Scaffolds for tissue repair must provide structural and biochemical cues to initiate the complex cascade of events that lead to proper tissue formation. Incorporating genes into these scaffolds is an attractive alternative to protein delivery since gene delivery can be tunable to any DNA sequence and genes utilize the cells’ machinery to continuously produce therapeutic proteins, leading to longer lasting transgene expression and activation of autocrine and paracrine signaling that are not activated with bulk protein delivery. In this review, we discuss the importance of scaffold design and the impact of its design parameters (e.g. material, architecture, vector incorporation, biochemical cue presentation) on transgene expression and tissue repair.
