摘要: Cells, by interacting with surfaces indirectly through a layer of extracellular matrix proteins, can respond to variety physical properties, such as topography or stiffness. Polymer surface mobility is another property that less well understood but has been indicated hold the potential modulate cell behavior. related glass-transition temperature (Tg) system, point at which polymer transitions from an amorphous solid more liquid-like state. This work shows changes in translate interfacial proteins adsorbed on material surface. study utilized family polyalkyl acrylates similar chemistry different degrees mobility, obtained increasing length side chain. These materials are used, conjunction fluorescent fibronectin, determine this protein constitutes initial cell–material interface. Fu...
