Definition of Xenopus in English:



  • The African clawed frog, much used in embryological research and formerly in pregnancy testing, as it produces eggs in response to substances in the urine of a pregnant woman.

    • ‘The central pattern generator in Xenopus embryos has been particularly well studied by Roberts and his colleagues.’
    • ‘Similarly, studies on the frog Xenopus laevis show POMC mRNA expression in the same regions.’
    • ‘Genome duplications are also proposed to have occurred in fish, maize, Arabidopsis, S. cerevisiae, and Xenopus.’
    • ‘Similar antero-posterior pelvic movements have been observed in the aquatic frog Xenopus during swimming.’
    • ‘The new species, X. arabiensis, differs from other Xenopus in its long maxilla and maxillary tooth row.’
    • ‘They were first isolated from the African clawed frog, Xenopus laevis.’


Late 19th century: modern Latin, from xeno- ‘strange’ + Greek pous foot.
