Figure S1: Validation of pSmad1/5/8 staining in response to BMP manipulation. (A): Injection of stage 9 Xenopus embryos with recombinant BMP4 led to increased Smad1/5/8 phosphorylation and nuclear localization. (B): The percentage of nuclei positive for the pSmad signal is significantly higher in BMP-treated than in control embryos (Student's t-test). (C): Knocking down BMP2, BMP4 and BMP7 with specific morpholino oligonucleotides inhibited Smad1/5/8 phosphorylation. Embryos were injected with either GFP mRNA alone (upper row) or GFP mRNA and the BMP2/4/7 MOs (lower row). The pSmad1/5/8 signal was lost in cells that received the BMP2/4/7 MOs, but not in those that received only the GFP mRNA.
