Experiments on Ciona intestinalis [PDF]
SINCE I had the pleasure of making copies, the only ones, I think, of Dr. Kammerer's photographs of Ciona during his visit to England, and believe that Prof. MacBride is not at the moment in possession of a complete set, I am taking the liberty of supplying the details requested by Mr. Cunningham in his letter to NATURE of December 15.

Refining the Ciona intestinalis model of central nervous system regeneration. [PDF]
BACKGROUND: New, practical models of central nervous system regeneration are required and should provide molecular tools and resources. We focus here on the tunicate Ciona intestinalis, which has the capacity to regenerate nerves and a complete adult ...

Identical sets of methylated and nonmethylated genes in Ciona intestinalis sperm and muscle cells [PDF]
BackgroundThe discovery of gene body methylation, which refers to DNA methylation within gene coding region, suggests an as yet unknown role of DNA methylation at actively transcribed genes.

THE PHOTIC SENSITIVITY OF CIONA INTESTINALIS [PDF]
1. Ciona possesses two means of responding to an increase in the intensity of illumination. One is by means of a local reaction; the other is by a retraction reflex of the body as a whole. 2. The "ocelli" are not photoreceptors. The photosensitive area is in the intersiphonal region containing the neural mass.

ACROSOME DIFFERENTIATION IN THE SPERMATOGENESIS OF CIONA INTESTINALIS* [PDF]
The process of acrosome formation in the course of spermatogenesis of Ciona intestinalis has been investigated. At the flute-beak-shaped tip of the head of the mature spermatozoon a small acrosomal vesicle(s) is described. The vesicles migrate to a region where the outer and inner nuclear membranes fuse thus giving rise to a "dense plate".

An organismal perspective on C. intestinalis development, origins and diversification
The ascidian Ciona intestinalis, commonly known as a ‘sea squirt’, has become an important model for embryological studies, offering a simple blueprint for chordate development.

Functional Divergence of Glycoprotein Hormone Receptors [PDF]
Two lamprey glycroprotein hormone receptors (lGpH-R I and II) highly similar with gnathostome GpH-Rs were cloned from sea lamprey testes and thyroid, respectively.

The nervous system of ascidians is an excellent model system to provide insights into the evolutionary process of the chordate nervous system due to their phylogenetic positions as the sister group of vertebrates.
