LookMa,NoArchenteron!Sulfatesroleinseaurchinearlydevelopment

ObjectiveTo observe the role sulfate plays in sea urchin gastrulation, and to replicate the findings of Karp and Solursh, that sea urchin embryos fail to gastrulate without sulfate. To test whether endoderm differentiation can occur in the absense of the movements of gastrulation.AbstractSea urchin development requires not only internally produced signals, but also materials incorporated from the environment.
