The sea urchin embryo has been a favorite material for the study of gastrulation and morphogenesis. Among the first attempts to understand morphogenesis in terms of cell behavior is found in the pioneering work of Gustafson and Wolpert (1967), which served as a powerful stimulus for more recent studies of morphogenesis. We wish to present here some ideas on what we do not know about sea urchin gastrulation, and to indicate different approaches being used in our laboratory to address these questions about the cellular and molecular basis of morphogenesis in sea urchin embryos.
