Outline of Final Research Achievements

The adult bodies of most animals have three perpendicular axes. These body axes are established during early embryogenesis. It is important to know how the direction and polarity of these axes are specified and how various tissues are patterned along these axes. In this project, we analyzed the mechanisms of patterning of some cell types along three embryonic axes, which are the animal-vegetal, anterior-posterior, and left-right axes, using urochordates (tunicates); the ascidian, Halocynthia roretzi, and the appendicularian, Oikopleura dioica.
