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

Immunolocalization is an essential technique for studying protein distribution in Xenopus species, enabling researchers to map endogenous protein expression during development and analyze responses to various treatments. This technique is also useful to detect epitope-tagged proteins, tagged morpholinos, and tracers.

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.

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.

Abstract Amphibian embryos have a prominent place among the species used to study vertebrate embryonic development. There is a long and distinguished history of experimental manipulations that were carried out in salamanders and newts.

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 ...

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.

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 ...

Abstract Ribosomal RNA synthesized by hybrid frogs from the cross between Xenopus laevis and Xenopus mulleri was analyzed by molecular hybridization with purified ribosomal DNA from each species. Although the 18 S and 28 S rRNA sequences are indistinguishable between these two species, the remaining 10% of the 40 S rRNA precursor molecule of each ...
