Abstract
Pigs have anatomical and physiological characteristics similar to humans; therefore, genetically modified pigs have the potential to become a valuable bioresource in biomedical research. In fact, considering the increasing need for translational research, pigs are useful for studying intractable diseases, organ transplantation, and regenerative medicine as large-scale experimental animals with excellent potential for extrapolation to humans. With the advent of zinc finger nucleases (ZFNs), breakthroughs in genome editing tools such as transcription activator-like effector nucleases (TALENs) and clustered regularly interspaced short palindromic repeats (CRISPR)-CRISPR associated protein 9 (Cas9) have facilitated the efficient generation of genetically modified pigs. Genome editing has been used in pigs for more than 10 years; now, along with knockout pigs, knock-in pigs are also gaining increasing importance. In this chapter, we describe the establishment of gene-modified cells (nuclear donor cells), which are necessary for gene knockout and production of knock-in pigs via somatic cell nuclear transplantation, as well as the production of gene knockout pigs using a simple cytoplasmic injection method.
