Ascidian embryogenesis and the origins of the chordate body plan

Curr Opin Genet Dev. 1998 Aug;8(4):457-63. doi: 10.1016/s0959-437x(98)80118-4.

Abstract

For more than a century, ascidians have been a widely used system for classic embryological studies. Ascidians possess simple, well-defined cell-lineages, compact genomes, rapid development and world-wide distribution. Transgenic DNA can be introduced into developing embryos using simple electroporation methods. The ascidian larva represents the most simplified chordate body plan and provides a useful model for studying the molecular pathways underlying the morphogenesis and differentiation of the notochord and neural tube.
