Outline of Final Research Achievements

In the term, I introduced and mated XTTGFP/XTTFP female mice (XTTGFP: Tsix inducible and X-linked GFP allele) with XTX/Y male mice (XTX: Xist inducible allele) to establish XTTGFP/XTX Embryonic stem cells (ESCs). Subsequently, I knocked-in the mCherry gene using CRISPR/Cas9 system into the XTX allele and introduced the Cas9 gene into the ESC to obtain XTTGFP/XTXmcherry Cas9 ESC. The ESC was converted to EpiSC. CRISPR library was amplified, and then the screening system has been established.
