Research Abstract

In this study, we found that although lamprey naso-hypophyseal placode develops as a single median thickening, nasal- and hypophyseal placode specific genes were already expressed separately before placode thickening. In order to track the cell lineage of the nasal placodal area, we succeeded to inject DiI focally at the pre-placodal area. Also, to trace cell movements, we injected a fluorescence protein at 1 cell stage and succeeded to observe fluorescein signals in this animal. Regarding hagfishes, we obtained a few fertilized eggs. We are preparing to analyze their gene expression patterns.
