| Outline of Final Research Achievements |
How cells divide and differentiate is a fundamental question in organismal development; however, analyzing differentiation processes in various cell types is laborious and sometimes impossible. Phylogenetic analysis is usually used to reconstruct evolutionary processes based on inherent characters. It could also be used to reconstruct developmental processes based on the developmental changes during cell proliferation and differentiation. In this study, genome-wide epigenetic information from differentiated cells was used to perform phylogenetic analyses. As a result, it was shown that the hierarchical differentiation processes and epigenetic status of differentiating progenitor cells could be inferred based on genom-wide DNA methylation information for murine hematopoiesis. This analysis was also applied to various differentiated cells of human.
