Figure 4. Ventralized Embryos Injected with noggin and Xwnr-8 RNAs Figure shows i representative ventralized embryos injected with noggin (delta) A or Xwnf-8 RNAs. Xenopus embryos ventralized by UV irradiation before the first cleavage were injected into one blastomere at the 4-cell stage with 1, 10, or 100 pg of either nogginA5’ or Xwnr-8 RNAs in a volume of IO nl. All embryr JS shown are the same age as the control embryos (approximately stage 41) which were not UV treated or injected. Also shown are non-injected UV-treated embryos.
