We discuss recent progress in understanding how cell fates are specified along the animal–vegetal axis of the sea urchin embryo. This process is initiated by cell-autonomous, maternally directed, mechanisms that establish three unique gene-regulatory domains. These domains are defined by distinct sets...

The general picture emerging from many studies in deuterostomes and protostomes is that β-catenin has an important function in the early polarization of the animal–vegetal axis of the embryo (Martin and Kimelman, 2009). Similar to prebilaterian animals, β-catenin is vegetally localized in ...

Symmetry-breaking events triggered by the fertilizing sperm remodel this primary animal–vegetal (a–v) axis to establish the embryonic (D–V, A–P) axes. To understand how this radial a–v polarity of eggs is established, we have analyzed the distribution of mitochondria, mRNAs, microtubules ...

Furthermore, we consider in detail only the first steps in the specification of major regions of the embryo--PMCs, SMCs, endoderm, and ectoderm--whose anlage are arranged in that order along the axis from vegetal to animal. We begin with the VSM that is required to specify mesoderm and ...
