| Research Abstract |
Ascidians are the marine invertebrate that is most closely related to vertebrates. Colonial tunicates propagate by means of both sexual and asexual reproduction, and they can regenerate gonads and germ cells even though gonad components are completely extirpated from the colony. This study has disclosed that Myc/ Piwi-expressing cells are reserved in the hemocoel, and that they respond to BMP to express germline-specific gene Vasa, enabling the regeneration of germline cells and tissues.
