Members of the Rho family including small GTPase Cdc42 have been shown to play multiple roles in cell regulation, including regulation of cytoskeletal organization, cell migration, proliferation, and apoptosis. However, their tissue-specific roles in vivo, especially in limb bud mesenchyme, remain largely unknown. Herein, we report that conditional deletion of Cdc42 in AER dose not change the limb development, however, knockout of Cdc42 in mesenchymal stem cells of li...
