Ascidian cytotoxic cells: state of the art and research perspectives [PDF]
Invertebrate Survival Journal, 2012 Ascidian cytotoxic cells are multivacuolated cells, variable in morphology, abundantly represented in the circulation, playing important roles in ascidian immunosurveillance.

Protostigmata in ascidians [PDF]
Proceedings of the Royal Society of London. Series B, Containing Papers of a Biological Character, 1913 It has been showed that at a certain stage in the ontogeny of Ascidians there is usually a definite number of stigmata or gill slits, which are elongated dorsorventrally and arranged in a longitudinal series on each side of the pharynx. To these the name protostigmata was given by Garstang in 1892.

New records of Aplousobranch ascidians to Indian waters from Andaman Islands
Journal of Threatened Taxa, 2017 Aplousobranchia represents the largest order under the class Ascidiacea. Two reef associated aplousobranch ascidians, Rhopalaea macrothorax Tokioka, 1953 under the family Diazonidae and Clavelina robusta Kott, 1990 under the family Clavelinidae, found ...

Bijdragen tot de Dierkunde, 1924 Through the kindness of Dr. C. J. VAN DER HORST of Amsterdam, I have had the opportunity of examining and reporting on the collection of ascidians that he made at Curaçao, Dutch West Indies, in April and May, 1920. The collection represents only the littoral fauna of the island; all the specimens appear to have been obtained in very shallow water on ...

Cellular aspects of allorecognition in the compound ascidian Botrylloides simodensis
Invertebrate Survival Journal, 2014 When colonies of the compound ascidian Botrylloides simodensis contact each other at their cut surfaces, either fusion or rejection occurs. Contact between genetically compatible colonies leads to the complete fusion of their tunics and vasculature ...

Ascidian gene-expression profiles.
Genome biology, 2002 With the advent of gene-expression profiling, a large number of genes can now be investigated simultaneously during critical stages of development. This approach will be particularly informative in studies of ascidians, basal chordates whose genomes and embryology are uniquely suited for mapping developmental gene networks.

Solitary ascidians embryos (Chordata, Tunicata) as model organisms for testing coastal pollutant toxicity [PDF]
Invertebrate Survival Journal, 2009 Marine coastal communities are daily exposed to several chemical compounds commonly used in agriculture and industrial activities. Therefore, toxicological studies evaluating the effects of these compounds on marine organisms are of primary importance ...
