摘要：
The disclosure provides methods for increasing genome stability of an embryonic stem (ES) cell or induced pluripotent stem (iPS) cell, increasing telomere length in an ES or iPS cell, or both, for example by contacting an ES or iPS cell with an agent that increases expression of Zscan4 in the cell. Methods for increasing the genome stability in a population of ES or iPS cells, increasing telomere length in a population of ES or iPS cells, or both, are provided, for example by selecting Zscan4+ ES or iPS cells from the population of ES or iPS cells (which can include both Zscan4+ and Zscan4− ES or iPS cells). Therapeutic methods of using ES or iPS cells expressing Zscan4 are also provided. Further provided are methods of treating cancer by administering a Zscan4 polynucleotide or Zscan4 polypeptide. Also provided are methods of inducing differentiation of isolated ES or iPS cells into germ cells.
