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. WebThis work identifies an intrinsic stochastic mechanism through which positive feedback alone is sufficient to account for the spontaneous establishment of a single site of polarity, and finds that the polarization frequency has an inverse dependence on the number of signalling molecules: the frequency of polarization decreases as theNumber of molecules becomes …
