Supplementary Material. Fig. S2 Pronephric phenotype induced by injection of MoPax2.2. Whole mount in situ hybridization for tubule and glomus marker genes. Embryos were injected with MoPax2.2 at the 4-cell stage, in the equatorial region of both left blastomeres. They were cultured until the tailbud stages 3335 (A) or 25 (B) and analyzed by in situ hybridization with specific probes for the indicated genes. For each embryo, injected (aq) and uninjected (aq) sides are shown. Pax2 depletion does not lead to any change in the expression of pronephric marker genes at stage 25. At the late tailbud stage, gene expression in the proximal part of the tubule, including nephrostomes, is affected by MoPax2.2 while expression in the distal tubule is not modified except for the terminal differentiation marker clcnkb1 whose expression is completely inhibited. Expression of the glomus marker genes wt1 and nephrin is not significantly affected in MoPax2.2 injected embryos. Insets show higher magnification of the anterior pronephric territory. Numbers indicate how many embryos showed the phenotype among the total number of injected embryos. | |||||||||||

Supplementary Material. Fig. S3 Pronephric phenotype induced by co-injection of MoPax8 and MoPax8.B. Whole mount in situ hybridization for tubule and glomus marker genes. Embryos were injected with MoPax8.B alone or in co-injection with MoPax8 at the 4-cell stage, in the equatorial region of both left blastomeres. They were cultured until the tailbud stages 3335 (A), early tailbud stage 2325 (B) and analyzed by in situ hybridization with specific probes for the indicated genes. For each embryo, injected (av) and uninjected (av) sides are shown. A strong reduction of the tubule marker genes (pax2, odf3, smp30, lhx1, hnf1b, pax2, hrt1, and evi1) expression is observed in response to the injection while the glomus markers wt1 and nephrin are still expressed. Insets show higher magnification of the anterior pronephric territory. |
