Abstract: Pig has always been the focus of establishing a big ungulate animal ES cell lines because of its convenient source, genetic similarity with humans, and their importance in animal husbandry, but little development is achieved. Induced pluripotent stem cells technology creates a new method of reprogramming somatic cells to pluripotent state. As the pig iPS cells is established and perfected, pig ES cells will be established in the coming years. The pig iPS cells will give a hint on other livestock ES cells. On the other hand, pig iPS cells can be used to improve the efficiency of transgenic cloning pigs to conduct effective breeding and conservation of breeds. It is particularly important that the pig iPS cells can provide new model for human medical research, a new donor cells for human tissue and organ engineering, and have extensive and far-reaching impact on the biomedical field. Here, we briefly review the major progress of iPS cells, and emphasize current state of pig iPS cells and its application prospect in biomedicine and animal husbandry in order to provide a useful reference for researchers working in this area.

Key words: embryonic stem cells, application prospect, pig, induced pluripotent stem cells
