Born equal: dual safeguards for daughter cell size symmetry

Abstract

Development and homeostasis require repeated symmetric cell divisions, which in turn depend on a centered mitotic spindle. In this issue, Kiyomitsu and Cheeseman uncover two mechanisms that ensure correct spindle positioning in anaphase: cortical dynein for pulling the spindle to the cell center and asymmetric membrane elongation that adjusts the position of the cell center to the cleavage plane.
