Fig. 1. Dose-dependence of RA phenotypes. Xenopus embryos at stage 9 were treated for 30 min with increasing concentrations of RA and allowed to develop to stage 40. There is a truncation of anterior pattern and concurrent failure of tail development which increases with the dose of RA. The embryo treated with 0.5/XM has two small eyes and the least apparently altered morphology, while the embryo at \jiu has a single median cyclopic eye. Eyes do not develop in embryos treated with 2.5 im RA or higher concentrations, and development of the heart and visceral arch skeleton is also impaired. Image published in: Papalopulu N et al.
