<physics> Literally having poles (like a magnet), but used to describe cells that have one or more axes of symmetry.

<cell biology> In epithelial cells, the polarity meant is between apical and baso lateral regions, in moving cells, having a distinct front and rear. Some cells seem to show multiple axes of polarity (which will hinder forward movement).
