Transgenic Xenopus Production


Transient transgenic gene expression in microinjected embryos of Xenopus laevis offers a relatively simple, yet versatile and economical experimental system for the molecular analysis of vertebrate embryogenesis.

Keywords: Xenopus laevis; microinjection; embryos; developmental biology; heterologous gene expression

Rapid development of Xenopus laevis. In vitro fertilized Xenopus eggs can be microinjected with RNA or DNA to promote ectopic gene expression in developing embryos. Within 48 hours, seminal events such as gastrulation, neurulation and the establishment of a rudimentary neuromuscular system take place, allowing scientists to dissect the role(s) of individual proteins in a well‐characterized model of early vertebrate development. Using microinjected Xenopus embryos, many key molecules involved in mesoderm induction, neurogenesis and the establishment of axial polarity have been identified. Modified from Seidman et al.
