A redescription of Syncarpa composita (Ascidiacea, Stolidobranchia) with an inference of its phylogenetic position within Styelidae [PDF]
ZooKeys, 2019 Two species of styelid colonial ascidians in the genus Syncarpa Redikorzev, 1913 are known from the northwest Pacific. The valid status of the lesser known species, Syncarpa composita (Tokioka, 1951) (type locality: Akkeshi, Japan), is assessed here.

The hemocytes of Polyandrocarpa mysakiensis: morphology and immune-related activities [PDF]
Invertebrate Survival Journal, 2009 A preliminary study of the hemocytes of developing buds of the compound ascidian Polyandrocarpa misakiensis was carried out at the light microscope level for a better understanding of their biological role. Similarly to other ascidians, P.

Morula Cells and Histocompatibility in the Colonial Ascidian Botryllus schlosseri [PDF]
Zoological Science, 1995 Abstract The role of morula cells (MC) in the formation of necrotic regions characterizing the rejection reaction between incompatible (i.e. nonfusible) colonies was investigated in the colonial ascidian Botryllus schlosseri. These blood cells share several chemical and histochemical properties with the pigment of the necrotic masses: both of them show

Modular co-option of cardiopharyngeal genes during non-embryonic myogenesis
EvoDevo, 2019 Background In chordates, cardiac and body muscles arise from different embryonic origins. In addition, myogenesis can be triggered in adult organisms, during asexual development or regeneration.

Colony Specificity in the Xenogeneic Combinations among Four Botrylloides Species (Urochordata, Ascidiacea) [PDF]
, 2002 Xenogeneic rejection reactions were histologically examined among four compound ascidians of the genus Botrylloides; B. simodensis, B. lentus, B. fuscus and B. violaceus, to compare with the allogeneic rejections of these species.
