Ex. 6.1
proteins often adsorb to biomaterial surfaces implanted in vivo or exposed to serum-containing media in vitro.
Many biomaterials do notsupport cell adhesion prior to adsorption of a protein layer. How might proteins facilitate adhesion of cells to a biomaterial?
Hint: consider to coat ECM proteins of biomaterial surface.
