| Outline of Final Research Achievements |
We established a novel experimental system named ‘TGP line’ which enables us to investigate cellular and molecular mechanisms underlying limb regeneration in adult newts by combination of a highly efficient transgenic technique (TG) and tissue transplantation techniques (TP). Utilizing this system, here we carried out cell lineage tracing in the limb regeneration, and found that larval and adult newts regenerate their limbs by different cellular mechanisms. In addition, in the adult newt, we found that the key tissues of the limb regeneration, such as the skin, muscles, bones and nerves, rigidly give rise to the same type of tissues, with a few exceptions. These findings would certainly contribute to understanding of differences in regeneration-competency among vertebrates.
