Alterations in the Xenopus retinotectal projection by antibodies to Xenopus N-CAM
Developmental Biology, 1988The patterned neural projection from the eye to the optic tectum of lower vertebrates (the retinotectal projection) has been proposed to be ordered by interactions between the optic nerve fibers and their surrounding tissues. To investigate the role of one such defined cell interaction, agarose implants containing antibodies to the neural cell adhesion

Annual Review of Immunology, 1989
Presentation des elements du systeme immunitaire de Xenopus: systeme lymphoide, systeme d'histocompatibilite majeur, immunoglobuline. Le fonctionnement de ce systeme est considere (reponse immune, tolerance, diversite des anticorps) ainsi que son developpement.

Nature, 1958
IN several genera of the order Anura supernumerary limbs occur naturally1. They are usually extra hind limbs2. Polymely does not appear to have been reported in the genus Xenopus. The female toad (Xenopus laevis) described here came with a consignment of toads imported from South Africa in 1956. The toad measured 8.0 cm.

Husbandry of Xenopus tropicalis
2012Xenopus tropicalis combine the advantages of X. laevis, for example using explants and targeted gain of function, with the ability to take classical genetics approaches to answering cell and developmental biology questions making it arguably the most versatile of the model organisms. Against this background, husbandry of X.

Trends in Cardiovascular Medicine, 1994
The amphibian embryo provides a convenient experimental system with which to study myogenesis. The earliest steps in the formation of axial and cardiac muscle are accessible for investigation using both embryological and molecular approaches. We review the origins of skeletal and cardiac muscle in the Xenopus embryo, the molecular markers available to ...

The developmental mutants of Xenopus
The International Journal of Developmental Biology, 1992The 32 developmental mutants found in our laboratory have appeared in the course of the genetic analysis of adult Xenopus laevis issued from nuclear transfers, and of their progeny. These experiments originally were devised more than thirty years ago to test whether somatic nuclei had undergone irreversible changes during differentiation or whether ...

Neovascularization of the Xenopus embryo
Developmental Dynamics, 1997The receptor tyrosine kinase, Flk-1 or VEGFR-2, and its ligand, vascular endothelial growth factor (VEGF) are required for the development of the embryonic vasculature. Targeted disruption of either gene in mice results in the failure of vascular system formation.

Current Opinion in Genetics & Development, 1994
Although induction of neural tissue in vertebrates has been recognized since the experiments of Spemann and Mangold seventy years ago, only recently has the phenomenon been put onto a molecular footing. Three molecules, noggin, follistatin and fibroblast growth factor, have been shown to have neuralizing activity in various assays.
