Introduction

Sea Urchin- activinB expression

Some Recent Findings

Dynamics of Delta/Notch signaling on endomesoderm segregation in the sea urchin embryo. Croce JC, McClay DR. Development. 2010 Jan;137(1):83-91. PMID: 20023163

"Endomesoderm is the common progenitor of endoderm and mesoderm early in the development of many animals. In the sea urchin embryo, the Delta/Notch pathway is necessary for the diversification of this tissue, as are two early transcription factors, Gcm and FoxA, which are expressed in mesoderm and endoderm, respectively. Here, we provide a detailed lineage analysis of the cleavages leading to endomesoderm segregation, and examine the expression patterns and the regulatory relationships of three known regulators of this cell fate dichotomy in the context of the lineages."

The expression and distribution of Wnt and Wnt receptor mRNAs during early sea urchin development. Stamateris RE, Rafiq K, Ettensohn CA. Gene Expr Patterns. 2010 Jan;10(1):60-4. Epub 2009 Oct 22. PMID: 19853669

"In this study, we identified all Wnt and Wnt receptor mRNAs that are present in unfertilized sea urchin eggs and early embryos and analyzed their distributions along the primary (AV) axis. Our findings indicate that the asymmetric distribution of a maternal Wnt or Wnt receptor mRNA is unlikely to be a primary determinant of the polarized stabilization of beta-catenin along the AV axis. This contrasts sharply with findings in other organisms and points to remarkable evolutionary flexibility in the molecular mechanisms that underlie this otherwise very highly conserved patterning process."
