通过体细胞核移植(SCNT)生产动物是低效的,大约2%的微操作卵母细胞会足月并导致活产。然而,这是克隆转基因牲畜最常用的方法,因为一旦核供体细胞被稳定地转染,它就有助于获得转基因动物,更重要的是,在农场动物中,其他转基因方法被证明效率更低。在这里,我们描述了piggybac介导的转基因转位到猪原代细胞中,并使用这些转基因细胞作为核供体,通过SCNT产生转基因猪。通过piggyBac转位的基因转移为SCNT中使用的核供体细胞的转染提供了一种替代方法。
The production of animals by somatic cell nuclear transfer (SCNT) is inefficient, with approximately 2% of micromanipulated oocytes going to term and resulting in live births. However, it is the most commonly used method for the generation of cloned transgenic livestock as it facilitates the attainment of transgenic animals once the nuclear donor cells are stably transfected and more importantly as alternatives methods of transgenesis in farm animals have proven even less efficient. Here we describe piggyBac-mediated transposition of a transgene into porcine primary cells and use of these genetically modified cells as nuclear donors for the generation of transgenic pigs by SCNT. Gene transfer by piggyBac transposition serves to provide an alternative approach for the transfection of nuclear donor cells used in SCNT.
