Webtributed, enables cells to carry out specialized functions. While cell polarity is often induced by intracellular or extracellular spatial cues, spontaneous polarization (the so-called … 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 …
