Volume changes during active shape fluctuations in cells

13 May 2015 Taloni Alessandro Kardash Elena Salman Oguz Umut Truskinovsky Lev Zapperi Stefano La Porta Caterina A. M.

Cells modify their volume in response to changes in osmotic pressure but it is usually assumed that other active shape variations do not involve significant volume fluctuations. Here we report experiments demonstrating that water transport in and out of the cell is needed for the formation of blebs, commonly observed protrusions in the plasma membrane driven by cortex contraction...
