Fig. 2. Early appearance of RA phenotypes. The typical morphology of RA-treated embryos is shown at neural stage 16 in dorsal (A) and anterior (B) views. Embryos were both derived from a synchronous fertilisation of the same egg batch and one group of embryos at stage 9 was exposed to a 30min pulse of 0.5 or 1 /IM RA. Only the embryos treated with 1/JM are shown. In A note the thicker appearance of the neural folds (arrows) and elongation of RA-treated embryos in comparison to sibling control (C). In B note also neural fold thickening and the absence of a cement gland, indicated by an arrow in the control (C) embryo. Image published in: Papalopulu N et al. (1991) Copyright © 1991.
