Cell division orientation and planar cell polarity pathways.
The orientation of cell division has a crucial role in early embryo body plan specification, axis determination and cell fate diversity generation, as well as in the morphogenesis of tissues and organs. In many instances, cell division orientation is regulated by the planar cell polarity (PCP) pathways: the Wnt/Frizzled non-canonical pathway or the Fat/Dachsous/Four-jointed pathway. Firstly, us...
متن کاملCoordination of planar cell polarity pathways through Spiny-legs.
Morphogenesis and physiology of tissues and organs requires planar cell polarity (PCP) systems that orient and coordinate cells and their behaviors, but the relationship between PCP systems has been controversial. We have characterized how the Frizzled and Dachsous-Fat PCP systems are connected through the Spiny-legs isoform of the Prickle-Spiny-legs locus. Two different components of the Dachs...
متن کاملPlanar cell polarity in Drosophila.
In all multicellular organisms, epithelial cells are not only polarized along the apical-basal axis, but also within the epithelial plane, giving cells a sense of direction. Planar cell polarity (PCP) signaling regulates establishment of polarity within the plane of an epithelium. The outcomes of PCP signaling are diverse and include the determination of cell fates, the generation of asymmetric...
متن کاملPlanar cell polarity: fashioning solutions.
Scientists like to consider themselves as especially objective, but, however hard we try we cannot be very different from everyone else. Like them we helplessly absorb our knowledge, our perspectives, our valuation of whether something is exciting or boring from those around us. In this "extra view" I reflect on fashion, illustrating by a small discovery of ours, and discussing why it was not m...
متن کاملThe cell biology of planar cell polarity
Planar cell polarity (PCP) refers to the coordinated alignment of cell polarity across the tissue plane. Key to the establishment of PCP is asymmetric partitioning of cortical PCP components and intercellular communication to coordinate polarity between neighboring cells. Recent progress has been made toward understanding how protein transport, endocytosis, and intercellular interactions contri...
