We focus on regulatory events that occur in development. First we discuss some of the classical studies of gene expression in the embryogenesis of sea urchins and amphibians and then turn to some of the developmental events in fruit flies, the best characterized developmental system.

The developmental expression of polySia chain synthesis in sea urchin PSGPs during embryogenesis seems likely to be an excellent experimental system to elucidate what regulates poly sialylation. Because the sea urchin embryo is a developmental system composed of three cell types in which the cell fate and tissue rearrangements are extensively understood (Foltz and Lennarz, 1993), this model system may also be ideal for studying the functional role of polySia chains.
