| Outline of Final Research Achievements |
In order to establish a forward genetic system in human iPS cells to identify the unknown mutation related skin disease, we introduced loss of heterogeneity (LOH) by inducing chromosomal crossing over, under Bloom syndrome gene (BLM) deficient condition. The Tet-off system was introduced into the BLM gene Under the control of BLM gene expression, we successfully identified clones with occurring chromosomal crossing over. By checking the SNP, we confirmed homogeneity. This indicated that this clone have occurred homologous recombination on these region. Using this system, we are trying to identify the unknown mutation in some iPS cell lines related skin disease.
