| Outline of Final Research Achievements |
Some vertebrates such as teleosts and amphibians can regenerate their lost appendages, whereas mammalians have limited regeneration ability. In animals that have regenerative ability, the restart of cell proliferation occurs during regeneration. Although this phenomenon is well known as “dedifferentiation”, the mechanism of this dedifferentiation remains elusive. To elucidate this dedifferentiation mechanism, I tried to screen genes that are expressed in the dedifferentiated proliferative cells during zebrafish fin regeneration by using next-generation sequencing. I identified the 132 genes that are up-regulated their expression more than twice after fin amputation compared with those before fin amputation. I am planning to analyze the function of these genes in dedifferentiation processes.
