Actin and microtubules are dynamic polar polymers that are well suited for providing the structural basis for cell polarity. Nucleation and plus-end regulation are key mechanisms for the assembly of ...

Almost all cell types exhibit some form of polarity; cell polarity refers to the spatial differences in shape, structure and function within a cell, which enables the cell to carry out specialized ...

Cell migration is a fundamentally polarized process. Cell polarity during cell migration encompasses several aspects (Figure 1). It is important to distinguish random cell migration, in which cells ...

A previously unknown mechanism involving the protein Scribble helps maintain polarity in cells, according to a Northwestern Medicine study published in the Journal of Biological Chemistry. This new ...

A research team led by Prof. Boseok Kang at Sungkyunkwan University has uncovered the origin of polarity inversion, a long-standing phenomenon in polymer semiconductors that occurs only in certain ...
