De-regulation of anterior-posterior and dorso-ventral patterning upon β-catenin stabilization.

<p>Whole mount <i>in situ</i> hybridyzation of E9.5 (22–26 somites) wt (a,c,e,g,i) and β-catenin^stab (b,d,f,h,j) embryos using probes against <i>Gbx2</i> (a,b), <i>Otx2</i> (c,d), <i>Shh</i> (e,f), <i>Gli1</i> (g,h), <i>Pax3</i> (i,j). Arrows indicate changes in gene expression. In g and h, the embryos have 21–22 somites.
