Morphogenetic interactions before gastrulation in the amphibian, Xenopus laevis--regulation in blastulae.

T H E site of the future dorsal lip of the gastrula is already determined to a considerable degree at the grey-crescent region by the 8-cell stage, probably by means of interactions within the cortex (Curtis, 19626). But this determination is still easily disturbed because excision of the grey-crescent cortex from the 8-cell stage does not prevent the appearance of a dorsal lip. The embryo form...

Regional requirements for Dishevelled signaling during Xenopus gastrulation: separable effects on blastopore closure, mesendoderm internalization and archenteron formation.

During amphibian gastrulation, the embryo is transformed by the combined actions of several different tissues. Paradoxically, many of these morphogenetic processes can occur autonomously in tissue explants, yet the tissues in intact embryos must interact and be coordinated with one another in order to accomplish the major goals of gastrulation: closure of the blastopore to bring the endoderm an...

Apoptosis in amphibian development

Amphibians and more particularly X. laevis are models often used for studying apoptosis during embryonic development. Using several methods, searchers determined the localization of programmed cell deaths (PCD). Several experimental methods also have been used to understand the regulatory mechanisms of apoptosis, throughout development, contributing to elucidate the general action of several ge...

Gastrulation movements provide an early marker of mesoderm induction in Xenopus laevis

The first inductive interaction in amphibian development is mesoderm induction, in which an equatorial mesodermal rudiment is induced from the animal hemisphere under the influence of a signal from vegetal pole blastomeres. We have recently discovered that the Xenopus XTC cell line secretes a factor which has the properties we would expect of a mesoderm-inducing factor. In this paper, we show t...
