| Outline of Final Research Achievements |
We performed experiments to generate a novel synthetic rescue system in murine haploid ES cells. For conditional KO system in haploid ES cells, we first tried to insert tamoxifen- inducible cassette, ERT2-iCre-ERT2 into the Rosa 26 locus. Since homologous targeting in haploid ES cells was very low, we used ZFN for the targeting.
Meanwhile, production of CRISPR-gRNA library has bee reported. The library is able to disrupt both alleles of a gene of interest.
We modified both alleles of Oct4 to floxed ones and we introduced CRISPR-gRNA library to disrupt endogenous genes randomly. After disruption of Oct4 by activation of Cre with tamoxifen. We isolated undifferentiated clones. We are analyzing these clones right now.
