There are several types of cells in the ascidian tunic. Function of tunic is responsible for these cells, which are called as test cells. In the compound ascidian, Aplidian, yamazii (TOKIOKA) four types of test cells could be identified by the differential interference optics, histological section stained with hematoxylin and eosin, and that stained with Giernsa. Those are named as vacuolated filopodia, granular filopodia, mature morula cell and tunic vesicle. Latex beads introduced into the tunic were phagocytized by mature morula cells (MMCs). When tunic was damaged, a new wall was formed between damaged and healthy parts. The observations on the process of new wall formation revealed the participation of MMCs. Clear-cut gradient of the cell density was observed by the histological sections. The cell density was highest at new wall and gradually decreased towards healthy part. The cell density at damaged part was lower than that at healthy part. Therefore, the migration of test cells was indicated. MMCs may play an important role in tunic function such as phagocytosis and new wall formation.
