in addition , no significant differences in membrane fluidity and cell spreading were found between cho cells spreading on plasma fibronectin-coated cytodex 1 ( without denatured collagen ) and cytodex 3 ( with denatured collagen ) microcarriers , indicating that a surface layer of denatured collagen is not required for plasma fibronectin to promote cell spreading and to rigidify the cell surface membrane .
