| Abstract: | Shiro-uo (ice goby; teleost fish), Leucopsarion petersii, shows a unique cleavage pattern characterized by two tires of blastomeres at 8-cell stage, like that of echinoderm and amphibian embryo. Such a pattern is suitable to isolation and cell lineage experiments. In this study, cell lineage of germ-line was traced by histological observation and cell labelling experiment at the 8-cell stage. Primordial germ cells (PGCs) were first detected histologically at the 10-somite stage, and migrated to gonadal anlage at 10 days post-fertilization, through usual way described in other teleost species. When a single blastomere was labelled with tracer dye at 8-cell stage, both upper and lower tires generated labelled PGCs at gonadal anlage although upper tires occasionally. This result suggests that all blastomeres at the 8-cell stage have potential to produce PGCs in shiro-uo. |
