The 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...
متن کاملCell biology of planar polarity transmission in the Drosophila wing
The coordination of epithelial planar polarization is a critical step in the formation of well-ordered tissues. The process has been extensively studied in Drosophila, where genetic analysis has identified a set of "tissue polarity" genes that serve to coordinate planar polarity of cells in the developing wings, bristles and eyes. In the last several years, it has emerged that six of these gene...
متن کاملCell packing influences planar cell polarity signaling.
Some epithelial cells display asymmetry along an axis orthogonal to the apical-basal axis, referred to as planar cell polarity (PCP). A Frizzled-mediated feedback loop coordinates PCP between neighboring cells, and the cadherin Fat transduces a global directional cue that orients PCP with respect to the tissue axes. The feedback loop can propagate polarity across clones of cells that lack the g...
متن کاملModeling the control of planar cell polarity.
A growing list of medically important developmental defects and disease mechanisms can be traced to disruption of the planar cell polarity (PCP) pathway. The PCP system polarizes cells in epithelial sheets along an axis orthogonal to their apical-basal axis. Studies in the fruitfly, Drosophila, have suggested that components of the PCP signaling system function in distinct modules, and that the...
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...
