Like many other frogs, they are often used in laboratory as research subjects. Xenopus embryos and eggs are a popular model system for a wide variety of biological studies. This animal is used because of its powerful combination of experimental tractability and close evolutionary relationship with humans, at least compared to many model organisms. Xenopus has long been an important tool for in vivo studies in molecular, cell, and development…
