N2 - Ascidians (Ascidiacea, Tunicata) are very interesting for evolutionary studies as one of the key basal chordate groups. Ascidians have a unique cell type surrounding oocyte – test cells. This cell functions and origin are under discussion. There is a hypothesis about participation of test cells in larval tunic formation. The other one hypothesize that test cells are mesenchymal cells descendants as the blood cells. We found that antibodies against morula cell protein of ascidian Styela rustica bind antigens not only in morula cells but also in test cells in several species. The aim of this study was to compare ultrastructural characteristics of test cells in ascidians with different larval development, Styela rustica and Molgula citrina, members of order Stolidobranchiata. The test cell cytoplasm of M. citrina mature test cells is filled by the granules with diameter 2–4 mkm, and the rER cisterns. Granule material is rather dense and homogenous, it resembles dense core of morula cell complex granules. When th
