    ..We propose that Drosophila Mud, vertebrate NuMA and Caenorhabditis elegans Lin-5 (refs 5, 6) have conserved roles in the mechanism by which G-proteins regulate the mitotic spindle. ..

    ..Finally, we propose a model suggesting that Wg signaling regulates fine scale cell fates along the anterior-posterior axis, in part by creating an adhesion gradient and consider possible alternate explanations for our observations. ..

    ..This suggests that key aspects of neural stem cell biology might be conserved in brain development of insects and mammals. ..

    ..Mammalian epithelia also use this complex to regulate apical/basal polarity. Recent results have allowed us to compare the mechanisms regulating asymmetric cell division in Drosophila neuroblasts and the C. elegans zygote. ..

    ..We conclude that Aurora-A and Numb are novel inhibitors of neuroblast self-renewal and that spindle orientation regulates neuroblast self-renewal. ..

    ..Thus, Lgl and Dlg act in a common process that differentially mediates cortical protein targeting in mitotic neuroblasts, and that creates intrinsic differences between daughter cells. ..

    ..Thus, Loco can potentially regulate heterotrimeric G-protein signaling via two distinct modes of action during Drosophila neuroblast asymmetric divisions. ..
