Abstract:
The air-plasma treated poly(dimethylsiloxane) membrane with linear grooves and ridges is alternately assembled with poly(sodium 4-styrenesulfonate) (PSS)/poly(diallyldimethylammonium) chloride (PDADMAC) multilayers, which is then treated in a gradient solution of 3-5M NaCl, with the pattern direction parallel to the gradient. The synergetic effects of the surface topography and swelling gradient can effectively guide the unidirectional migration of single smooth muscle cells without impairment of their migration rate.

Role of Myosin in Cell Migration
Myosin II is a hexamer comprising two heavy chains with globular heads and coiled-coil tails, two regulatory light chains, and two essential light chains. The ATPase sites on the myosin heads hydrolyze ATP, and the released phosphate generates the force for contraction. It is...
