Rho GTPases in embryonic development

Abstract

In the last decade, several mouse models for RhoA, Rac1, and Cdc42 have emerged and have contributed a great deal to understanding the precise functions of Rho GTPases at early stages of development. This review summarizes our current knowledge of various mouse models of tissue-specific ablation of Cdc42, Rac1, and RhoA with emphasis on early embryogenesis, epithelial and skin morphogenesis, tubulogenesis, development of the central nervous system, and limb development.
