Colony Specificity in the Xenogeneic Combinations among Four Botrylloides Species (Urochordata, Ascidiacea) [PDF]
Zoological Science, 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.

Comparative 3D-anatomy of Appendicularian Endostyles (Tunicata, Chordata) - A Tale of Reduction. [PDF]
J MorpholAppendicularia are chordates that possess endostyles, a pharyngeal gland homologous to vertebrate thyroid. Here, we describe the detailed 3D‐anatomy of endostyles based on light‐ and electron microscopy. We identified seven cell types arranged in specific patterns.

Why Homoscleromorph Sponges Have Ciliated Epithelia: Evidence for an Ancestral Role in Mucociliary Driven Particle Flux. [PDF]
J Exp Zool B Mol Dev EvolEpithelia are typically ciliated, except in sponges. Of all Porifera only Homoscleromorphs have motile cilia on their epithelia. Our data highlight the presence of cilia and mucociliary particle transport as a common feature of metazoa and a secondary loss in other sponge lineages.
