Dlg, Scrib and Lgl regulate neuroblast cell size and mitotic spindle asymmetry

Roger Albertson & Chris Q. Doe

Asymmetric cell division is important in generating cell diversity from bacteria to mammals. Drosophila melanogaster neuroblasts are a useful model system for investigating asymmetric cell division because they establish distinct apical–basal cortical domains, have an asymmetric mitotic spindle aligned along the apical–basal axis, and divide unequally to produce a large apical neuroblast and a small basal daughter cell (GMC).
