| Outline of Final Research Achievements |
We have successfully established three induced disomy 21 iPS cell lines by genome editing technology from the original trisomy 21 iPS cells derived from a single individual with Down's syndrome. These induced three types of cells have different combinations of 21 chromosomes. The karyotypes of the induced disomy cells have been confirmed by means of chromosome spreading G-banding, short tandem repeat analysis, multiplex ligation-dependent probe amplification, and fluorescent in situ hybridization. Furthermore, we also classified them based upon the origin of deleted chromosome 21 by STR analysis. Following chromosome phasing by comparison of sequencing data with the 3 cell lines, we have subsequently succeeded in constructing a CRISPR/Cas 9 system for allele specific cleavage in multiple sites.
