Figure S5. Germ layer marker gene expression in xSuv4-20h double morphants. (A) Immuno-histochemistry on ctrl-MO and xSuv4-20h double-morphant tadpoles. Panels show representative cross-sections of neural tubes stained with antibodies against the histone epitopes indicated on top. Inj injected side. Squares on double-morphant sections represent the croped pictures shown in Figure 1D. (B-F) RNA in situ hybridization analysis of ctrl-MO injected and double morphant embryos at the indicated stages using probes against Chordin, Xnr-3 and Gooscoid (B), Krox20 and Otx2 (C), Pax-6 (D), N-CAM (E), FoxD5, Geminin, Zic2, Zic3, Sox3, Sox11 and VegT (F). Chordin, Xnr-3 and Gooscoid dorsal side views; animal pole is on the top. Krox20 - dorsal views, anterior on the left. Otx2 - anterior views, dorsal on the top. Pax-6 head region; rescued embryos included. N-CAM - dorsal views of stained embryos with the anterior on the left; rescued embryos included. FoxD5, Geminin, Zic2, Zic3 - dorsal views; injected halves are lineage-traced by coinjection of LacZ mRNA and subsequent βal staining (light blue). Sox2, Sox3 - dorsal views, anterior to the left. VegT - internal stain in bisected embryos. |
