Recently biologists at the University of Massachusetts Amherst led by Wei-lih Lee have identified a new molecular player in asymmetric cell division, a regulatory protein named She1 whose role in chromosome- and spindle positioning wasn't known before. Asymmetric cell division is important in the self-renewal of stem cells and because it ensures that daughter cells have different fates and functions.
