DEVELOPMENT The Dance of Development
The path from an egg into an adult organism requires a complex dance of thousands of genes. Imai et al. (see the Perspective by Lemaire) tracked the expression of regulatory genes on a cell-by-cell basis in the developing embryo of the sea squirt, Ciona intestinalis. The authors generated a map of the network of gene interactions from which they could extract information about specific developmental pathways, such as the formation of notochord, or brain. The results give a snapshot of development at an interesting point of evolution, from an organism that stands between invertebrates and vertebrates.
