    Dev Genes Evol 212:11-8. 2002
    ..However, even in such juveniles, positive cells newly appeared in the gonad rudiment at a later stage. This observation suggests that a compensatory mechanism regulates germline formation in C. intestinalis...

    Department of Marine Biotechnology, Faculty of Engineering, Fukuyama University, 729 0292, Japan
    Dev Genes Evol 212:50-3. 2002
    ..In the larva, the expression was seen in several cells of the visceral ganglion. These results suggest that ascidian larval motor neurons exist in the visceral ganglion...

    Dev Genes Evol 210:64-72. 2000
    ..In the tailbud, one or two hybridization signals were detected in the caudal endodermal strand. Based on these observations, we propose precursors of primordial germ cells in ascidians...

    Dev Growth Differ 45:369-76. 2003
    ..Under heat stress conditions, however, daf-21 mRNA was not only detected in germ cells, but also apparently expressed all over the body. In addition, the DAF-21 protein seemed to be localized in the perinuclear region of somatic cells...

    Development 134:1203-19. 2007
    ..These observations lead us to propose a model of metamorphosis whereby JNK activity in the CNS induces apoptosis in several adjacent tissues that compose the tail by inducing the expression of genes such as Ci-sushi...
