    To generate reproductive cells from mouse ES/iPS cells

    A research group including Dr. Katsuhiko Hayashi at Kyoto University succeeded in differentiating male mouse ES cells and iPS cells into primordial reproductive cells in vitro and induced sperms from the cells, to give healthy pups by in vitro fertilization in 2011. In 2012, they differentiated female mouse ES cells and iPS cells into primordial reproductive cells in vitro, grew them in culture with fetal mouse somatic cells that were to be ovaries, and transplant the cells into ovaries of other mice, to obtain unmatured ova. Then they grew the unmatured ova in vitro into mature ova, and give pups with these ova by in vitro fertilization. These studies on differentiation of ES or iPS cells into reproductive cells can contribute to developing reproductive medicine for humans in the future and therefore attracts attention in various related fields.
