Ultrastructure of the olfactory organ in the clawed frog, Xenopus laevis, during larval development and metamorphosis.
Development of the olfactory epithelia of the African clawed frog, Xenopus laevis, was studied by scanning and transmission electron microscopy. Stages examined ranged from hatching through the end of metamorphosis. The larval olfactory organ consists of two chambers, the principal cavity and the vomeronasal organ (VNO). A third sensory chamber, the middle cavity, arises during metamorphosis. I...
متن کاملResponse of larval Xenopus laevis to atrazine: assessment of growth, metamorphosis, and gonadal and laryngeal morphology.
Larval Xenopus laevis were exposed to one of four concentrations of atrazine (0, 1, 10, or 25 microg/L, 11 replicate tanks per treatment, 60-65 larvae per replicate) dissolved in an artificial pond water (frog embryo teratogenesis assay- Xenopus [FETAX]) medium beginning 48 h after hatching until the completion of metamorphosis. Separate groups of larvae (six replicate tanks per treatment, 60-6...
متن کاملA developmental switch induced by thyroid hormone: Xenopus laevis metamorphosis.
Thyroid hormone induces the complete metamorphosis of anuran tadpoles into juvenile frogs. Arguably, anuran metamorphosis is the most dramatic effect of a hormone in any vertebrate. Recent advances in pharmacology and molecular biology have made the study of this remarkable process in the frog Xenopus laevis attractive to developmental biologists and endocrinologists alike. In particular, the a...

development, and the heart needs to function before it is completely differentiated and matured. Despite the early onset of the heart beat and blood circulation, their physiological role in oxygen transport has been questioned (Pelster, 1999; Pelster and Burggren, 1996). In small larvae such as those of Xenopus laevis and zebrafish, diffusion of oxygen through the body surface alone is consider...
متن کاملIntegrin Linked Kinase (X-ILK) Function during Embryonic Development and within Adult Tissues of Xenopus laevis
Integrin linked kinase (ILK) is a serine/threonine protein kinase implicated in the phosphatidylinositol 3’kinase (PI3’K) pathway. Integrin linked kinase has been investigated in different organisms such as mammalian systems (human, mice, rat), insects (Drosophila) and nematodes (Cenorhabditis elegans), however to date little data regarding ILK research on amphibians has been reported. In...
