Mother centrioles are kicked out so that starfish zygote can grow
نویسنده
چکیده
Most oocytes eliminate their centrioles during meiotic divisions through unclear mechanisms. In this issue, Borrego-Pinto et al. (2016. J Cell. Biol. http://dx.doi.org/10.1083/jcb.201510083) show that mother centrioles need to be eliminated from starfish oocytes by extrusion into the polar bodies for successful embryo development.

Distinct mechanisms eliminate mother and daughter centrioles in meiosis of starfish oocytes
Centriole elimination is an essential process that occurs in female meiosis of metazoa to reset centriole number in the zygote at fertilization. How centrioles are eliminated remains poorly understood. Here we visualize the entire elimination process live in starfish oocytes. Using specific fluorescent markers, we demonstrate that the two older, mother centrioles are selectively removed from th...
متن کاملCentriole Age Underlies Asynchronous Primary Cilium Growth in Mammalian Cells
Primary cilia are microtubule-based sensory organelles that play important roles in development and disease . They are required for Sonic hedgehog (Shh) and platelet-derived growth factor (PDGF) signaling. Primary cilia grow from the older of the two centrioles of the centrosome, referred to as the mother centriole. In cycling cells, the cilium typically grows in G1 and is lost before mitosis, ...
متن کاملAtypical centrioles during sexual reproduction
Centrioles are conserved, self-replicating, microtubule-based, 9-fold symmetric subcellular organelles that are essential for proper cell division and function. Most cells have two centrioles and maintaining this number of centrioles is important for animal development and physiology. However, how animals gain their first two centrioles during reproduction is only partially understood. It is we...
متن کاملA homeostatic clock sets daughter centriole size in flies
Centrioles are highly structured organelles whose size is remarkably consistent within any given cell type. New centrioles are born when Polo-like kinase 4 (Plk4) recruits Ana2/STIL and Sas-6 to the side of an existing "mother" centriole. These two proteins then assemble into a cartwheel, which grows outwards to form the structural core of a new daughter. Here, we show that in early Drosophila ...
متن کاملCentriole Remodeling during Spermiogenesis in Drosophila
The first cell of an animal (zygote) requires centrosomes that are assembled from paternally inherited centrioles and maternally inherited pericentriolar material (PCM) [1]. In some animals, sperm centrioles with typical ultrastructure are the origin of the first centrosomes in the zygote [2-4]. In other animals, however, sperm centrioles lose their proteins and are thought to be degenerated an...
