WebInsect bristle polarity Planar cell polarity (PCP) was first described in insects where the hairs and bristles on the wings and abdomen have a precise polarity. In the case of the abdomen, they have an anterior–posterior orientation (Module 8: Figure Drosophila planar cell polarity), whereas on the wing, they lie along the proximal–distal axis (see panel a … Web15 de jul. de 2014 · Cell polarization, in which intracellular substances are asymmetrically distributed, enables cells to carry out specialized functions. While cell polarity is often induced by intracellular or extracellular spatial cues, spontaneous polarization (the so-called symmetry breaking) may also occur in the absence of spatial cues.
