Geometric control of ciliated band regulatory states in the sea urchin embryo
... The trapezoidal ciliated band (CB) of the postgastrular sea urchin embryo surrounds the oral ectoderm, separating it from adjacent embryonic territories. Once differentiated, the CB is composed of ...

LvNumb works synergistically with Notch signaling to specify non skeletal mesoderm cells in the sea urchin embryo
... Activation of the Notch signaling pathway segregates the non-skeletogenic mesoderm (NSM) from the endomesoderm during sea urchin embryo development. Subsequently, Notch signaling helps specify the ...

Activation of the skeletogenic gene regulatory network in the early sea urchin embryo
... First, to further support the idea that pmar1 provides a positive regulatory input into alx1, we used F-WMISH to show that overexpression of Lvpmar1 was sufficient to activate Lvalx1 throughout the embryo (Fig. ...

Differential stability of β catenin along the animal vegetal axis of the sea urchin embryo mediated by dishevelled
... The methods used in the present study do not allow us to determine precisely when the polarity in β-catenin degradation first arises. It is therefore unclear whether differential stability along the A-V axis involves a ...

CBFβ is a facultative Runx partner in the sea urchin embryo
... Knockout of CBFb in mouse leads to embryonic lethality caused by a failure of hematopoiesis [12,13], a phenotype very similar to that caused by knockout of Runx1. As with RUNX1, chromosomal translocations involving CBFb ...

Dynamics of Delta/Notch signaling on endomesoderm segregation in the sea urchin embryo
... To transmit its signal the Delta/Notch pathway relies on the interaction between a receptor and a ligand that are both single-pass transmembrane proteins. A direct cell-to-cell contact is thus required for the Notch ...

Axial patterning interactions in the sea urchin embryo: suppression of nodal by Wnt1 signaling
... Nodal signaling is necessary and sufficient to impose DV polarity to cells in all three germ layers of the embryo (Duboc et al., 2010; Duboc et al., 2004) and its influence extends in a broad band imposing DV ...

Nodal and BMP2/4 pattern the mesoderm and endoderm during development of the sea urchin embryo
... In vertebrates, Nodal factors play conserved roles in the induction of the mesoderm and endoderm, in the formation of a dorsally located organising centre and in the establishment of left-right asymmetry (Shen, 2007). ...
