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.

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

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 ...

Studying Regeneration in Xenopus
2012For most Xenopus embryos, life is very short. The majority of research labs working with this model organism study the processes of early vertebrate patterning and morphogenesis. And quite rightly too, since over the last two decades labs across the world have provided the fate maps, animal cap assays, expression patterns, and functional screens that ...
