Results of combined antisense MoXat1 and MoXat3 injections in <i>Xenopus</i> embryos

<p>. Reduction of <i>Xotx2</i> (A–C or J–L, respectively for strong or slight reduction), <i>nrp-1</i> (D–F, strong; M–O, slight) and <i>Twist</i> (G–H, strong; P–Q, slight) expression is observed on the injected side of embryos (inj), compared to uninjected side (un). Strong or weak reduction (I, R respectively) of pharyngeal skeleton is observed on the injected side of antisense MO treated swimming tadpoles compared to control side. Beta-gal red staining traces injected side of embryos.</p>
