Frogs from the genusXenopus have long been used as model organisms in basic and biomedical research. These frogs have helped unlock key fundamental developmental and cellular processes that have led to important scientific breakthroughs and have had practical application in embryology, cancer research and regenerative medicine.Xenopus Development is a vital resource on the biology and development of these key model organisms, and will be a great tool to researchers using these frogs in  various disciplines of biological science.

Xenopus Development is divided into four sections, the first three highlight key processes in Xenopus development from embryo to metamophosis. These sections focus on the cellular processes, organogenesis and embryo development. The final section highlights novel techniques and approaches being used in Xenopus research.

Providing thorough and detailed coverage,Xenopus Development, will be a timely and welcome volume for those working in cell and molecular biology, genetics, developmental biology and biomedical research.

Provides broad overview of the developmental biology of bothXenopus laevis andXenopus tropicalisExplores cellular to systems development in key biomedical model organismsTimely synthesis of the field ofXenopus biologyHighlights key biomedical and basic biological findings unlocked byXenopus
