Abstract

The technique of in situ hybridization can be used to visualize the spatial and temporal pattern of gene expression during development. Ascidians are invertebrate chordates that develop with a fixed cell cleavage pattern into a tadpole larvae. The knowledge of the cell lineage allows the earliest steps of cell fate specification to be followed at a single cell resolution. This protocol describes preparation of Ciona intestinalis embryos, classical in situ hybridization protocol coupled with nuclear staining, and a guide to identify gene expression in specific precursors of the developing brain at neural plate stages of development.
