Characterization of XRap2's activity in Xenopus ectoderm. (A–D) Four-cell stage embryos were microinjected into the animal region with 100 pg XRap2, 2 ng BMP-4 or a combination as indicated. Animal caps were dissected at stage 8.5, cultured until stage 10.5 (A, D) or stage 27 equivalent (B, C) and analyzed by RT–PCR for expression of marker genes indicated. In (D), the Activin protein (Act) was added at 5 ng/ml to the animal caps at stage 8.5. ODC, a loading control; −RT, minus reverse transcription control sample.
