组织纳米转染(TNT)是一种电动基因转移技术,其被开发用于实现体内组织重编程。该方案描述了如何制造所需的硬件,通常称为TNT芯片,并将其用于体内TNT。用于TNT应用的硅空心针阵列以标准化和可重复的方式制造。在<1秒内,这些硅空心针阵列可用于响应于脉冲纳米穿孔将质粒递送到小鼠皮肤中的预定特定深度。组织纳米转染消除了使用病毒载体的需要,最大限度地减少了基因组整合或细胞转化的风险。TNT芯片制造过程通常需要5-6天,体内TNT需要30分钟。该协议不需要专门的专业知识,除了配备基本的纳米纤维工艺的洁净室。
Tissue nanotransfection (TNT) is an electromotive gene transfer technology that was developed to achieve tissue reprogramming in vivo. This protocol describes how to fabricate the required hardware, commonly referred to as a TNT chip, and use it for in vivo TNT. Silicon hollow-needle arrays for TNT applications are fabricated in a standardized and reproducible way. In <1 s, these silicon hollow-needle arrays can be used to deliver plasmids to a predetermined specific depth in murine skin in response to pulsed nanoporation. Tissue nanotransfection eliminates the need to use viral vectors, minimizing the risk of genomic integration or cell transformation. The TNT chip fabrication process typically takes 5–6 d, and in vivo TNT takes 30 min. This protocol does not require specific expertise beyond a clean room equipped for basic nanofabrication processes.
