The mechanisms involved in the generation of axial structures in the chick are well documented, yet, little is known about the actual factors that generate such a complex pattern. The recent demonstrations that all-trans-retinoic acid (RA) acts as a morphogen during limb development (Thaller and Eichele, 1987) lead us to examine whether during axis formation in the developing chick, RA could be one of the factors involved. We now show that retinoic acid can block a very unusual property of normal early chick embryonic cells, mainly their capacity to grow in semisolid medium. We also present experiments that suggest that RA may play a direct role during axis formation in the developing chick.

The correlation between cell-to-cell communication junctions at the 32-cell stage and the subsequent embryonic axis has been examined in Xenopus laevis Disturbances of embryonic axis formation were u.v. irradiation at the vegetal pole before 0.6 in the which generates embryos with dorsal axial embryos were treated with 100mM-lithium chloride 32-cell stage, which generates embryos with ventral The cell-to-cell transfer of Lucifer Yellow was used junctional permeability. Injections were made into cells, lying in tiers 1 and 2 of the 32-cell embryo, relative to the future dorsoventral axis of the embryo on the basis of differences in pigmentation. The Yellow transfer in the future dorsal half of the compared with that in the future ventral half for u.v.-irradiated and Li-treated embryos. Injected subsequently scored for axial developmenf for transfer frequencies. In control embryos at the 32- Yellow transfer was both more frequent and more dorsal regions than in future ventral regions, as In embryos that had been u.v. irradiated before 0.6 in cycle, Lucifer transfer was the same in both light and the animal hemisphere and at the low level ventral regions in normal embryos. These embryos reductions in dorsal axial structures. Embryos the first cell cycle, when u.v. irradiation no longer cytoplasmic movements initiated at fertilization, dorsoventral difference in Lucifer Yellow transfer and normal dorsoventral polarity.
