toplasmic polarization signaling proteins commonly divided into three groups called the Par, Scribbled, and Crumbs complexes, and activation of the small GTPases Rac1 and Cdc42 (Nelson 2009). The extrinsic polarization mechanism, on the other hand, provides spatial orientation cues to the cell from the environment, triggering the asymmetric distribution and activation of the complexes that make up the intrinsic mechanism. In early embryos, primary spatial cues take a variety of forms. ...
