On the spontaneous emergence of cell polarity

WebAbstract 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 extracel-lular spatial cues, spontaneous polarization (the so-called symmetry breaking) may also occur in the absence of spatial cues.
