During asymmetric mitosis, both in male Drosophila germline stem cells and in mouse embryo neural progenitors, the mother centrosome is retained by the self-renewed cell; hence suggesting that mother centrosome inheritance might contribute to stemness. We test this hypothesis in Drosophila neuroblasts (NBs) tracing photo converted centrioles and a daughter-centriole-specific marker generated by cloning the Drosophila homologue of human Centrobin. Here we show that upon asymmetric mitosis, the mother centrosome is inherited by the differentiating daughter cell. Our results demonstrate maturation-dependent centrosome fate in Drosophila NBs and that the stemness properties of these cells are not linked to mother centrosome inheritance. Asymmetric partitioning of centrosomes has been reported in Drosophila neuroblasts, but whether this type of division has implications for stem cell self-renewal is unclear. In this study, the authors show that the asymmetric division of the centrosomes correlates with the asymmetric fate of the cells and that the daughter centrosome is retained by the neuroblast.
