...Gil Jung Kim; Gaku Kumano; Hiroki Nishida Asymmetric cell division plays a fundamental role in generating various types of embryonic cell. In ascidian embryos, asymmetric cell divisions occur in the vegetal hemisphere in a manner similar to those found in Caenorhabditis elegans . Early divisions...

... (minor muscle lineage) of C. elegans embryos depends on the presence of cells of other lineages ( Priess and Thomson, 1987 ), as has also been shown to be the case in ascidian embryos, in this study. I thank Dr N. Satoh for his valuable advice and constant encouragement throughout the course...

...Takahito Nishikata; Izumi Mita-Miyazawa; Takuya Deno; Noriyuki Satoh ABSTRACT The myoplasm of Ciona intestinalis eggs, believed to contain cytoplasmic determinants responsible for muscle cell differentiation in ascidian embryos, emits weak pale-blue autonomous fluorescence. Utilizing this feature...
