title: [Pattern formation in the early embryogenesis of the clawed toad].
abstract: Establishment of egg polarity, separation of germ layers, appearance of animal-vegetal, dorsoventral and anteroposterior axis in Xenopus laevis embryos have been considered. The control of these processes by genes coding for growth factors, protooncogenes and homeobox-containing genes has also been reviewed.
