Abstract

Gene editing technologies, particularly CRISPR/Cas9, have emerged as transformative tools in genetic modification, significantly advancing the use of porcine embryos in biomedical and agricultural research. This review comprehensively examines the various methodologies for gene editing and delivery methods, such as somatic cell nuclear transfer (SCNT), microinjection, electroporation, and lipofection. This review, focuses on the advantages or limitations of using different biological sources (in vivo- vs. in vitro oocytes/embryos). Male germ cell manipulation using sperm-mediated gene transfer (SMGT) and testis-mediated gene transfer (TMGT) represent innovative approaches for producing genetically modified animals. Although these technologies have revolutionized the genetic engineering field, all these strategies face challenges, including high rates of off-target events and mosaicism. This review emphasizes the need to refine these methods, with a focus on reducing mosaicism and improving editing accuracy. Further advancements are essential to unlocking the full potential of gene editing for both agricultural applications and biomedical innovations.

期刊介绍： Genomics is a forum for describing the development of genome-scale technologies and their application to all areas of biological investigation. As a journal that has evolved with the field that carries its name, Genomics focuses on the development and application of cutting-edge methods, addressing fundamental questions with potential interest to a wide audience. Our aim is to publish the highest quality research and to provide authors with rapid, fair and accurate review and publication of manuscripts falling within our scope.
