Outline of Final Research Achievements |
In this study, evolution of animal morphogenesis was analyzed by developmental and molecular biological approaches focusing on body axis formation and adult rudiment formation during development of echinoderms. In results, it was identified that temnopleurid sea urchins were involved adult rudiment formation by a cell mass that is formed at the early larval stage and obtains higher regenerative potential. These results suggest that involvement of the cell mass formation in the adult rudiment formation causes to start to form the adult rudiment from the earlier stage and to give larvae regenerative potential to survive in environment.
