| Outline of Final Research Achievements |
Wnt/beta-catenin signaling pathway is conserved in numerous animal species, and greatly involved in homeostasis mechanism as well as various body developments. We hypothesized the involvement of Wnt/beta catenin, especially CBP/beta catenin signaling pathway is deeply associated with the reprograming of pluripotent stem cell（PSC）. In this study, we tried to develop the inducing and culture method of iPS cells independent of characteristics of donor cells. It was promoted reprogramming of fibroblasts to PSC not only in mice but also in human cells by activating the CBP/β-catenin pathway. In addition, it was observed that activation of CBP/β-catenin strongly and positively regulates the maintenance of undifferentiation of mouse PSC as naive state. These results suggest that activation of the CBP/β-catenin pathway is thought to be a highly efficient iPS cell induction and culture method.
