U0126 targets expressed in individual cells throughout the ectoderm. Wild type salt-and-pepper gene expression analysis by in situ hybridization of genes differentially regulated by U0126 treatments. All animals are either blastula [24 hours post fertilization (hpf) – A–F, M–R, Y-Zd] or gastrula (48 hpf – G–L, S–X, Ze–Zj) stages. All images are lateral views with the animal pole to the top. The insets correspond to surface views. Antisense probes used as indicated. Green stars in Zd and Zj indicate that this gene was upregulated under U0126 conditions. All other genes were downregulated
