    ANIMAL & CELL MODELS
  • mice with a keratinocyte-restricted deletion of the Cdc42 gene were born without obvious defects, but showed highly impaired hair coat development
  • conditionally deletion of Cdc42 gene in telencephalic neural progenitors from mouse embryos abolishes the apical localization of PAR6, aPKC, E-cadherin, beta-catenin, and Numb proteins in the neuroepithelium, and severely impairs the extension of nestin-positive radial fibers
