Efficient delivery of nucleic acid molecules into skin by combined use of microneedle roller and flexible interdigitated electroporation array.
Theranostics 2018
Rationale: Delivery of nucleic acid molecules into skin remains a main obstacle for various types of gene therapy or vaccine applications. Here we propose a novel electroporation approach via combined use of a microneedle roller and a flexible interdigitated electroporation array (FIEA) for efficient delivery of DNA and siRNA into mouse skin. Methods: Using micromachining technology, closely spaced gold electrodes were made on a pliable parylene substrate to form a patch-like electroporation array, which enabled close surface contact between the skin and electrodes. Pre-penetration of the skin with a microneedle roller resulted in the formation of microchannels in the skin, which played a role as liquid electrodes in the skin and provided a uniform and deep electric field in the tissue when pulse stimulation was applied by FIEA. Results: Using this proposed method, gene (RFP) expression and siRNA transfection were successfully achieved in normal mice skin. Anti-SCD1 siRNA electroporated via this method mediated significant gene silencing in the skin. Moreover, electroporation assisted by the microneedle roller showed significant advantages over treatment with FIEA alone. This allowed nucleic acid transportation at low voltage, with ideal safety outcomes. Principal conclusions: Hence, the proposed electroporation approach in this study constitutes a novel way for delivering siRNA and DNA, and even other nucleic acid molecules, to mouse skin in vivo , potentially supporting clinical application in the treatment of skin diseases or intradermal/subcutaneous vaccination.
