Outline of Final Research Achievements

This research project had been aimed for the derivation of cynomolgus monkey/rabbit interspecific chimera using blastocyst complementation methods. We achieved naive-like conversion of cynomolgus monkey ES/iPS cells, which can enhances their in vitro differentiation potential. According to the research project, it revealed that rabbit embryos were not suitable for the host of interspecific chimera production. On the other hand, following mice and rats, the 3rd true naive-iPS cells were successfully established form an endangered species, Tokudaia osimensis. We produced interspecific chimera and elucidated the sexual plasticity of the germ cells of the endangered species.
