Abstract

We examined the effect of existence of preadsorbed protein layers on cell adhesion. Mixed solutions of fibronectin (Fn) and albumin (BSA) were preadsorbed on serf-assembled monolayers presenting different functional groups including methyl, hydroxyl, carboxyl, and amine, and then human umbilical vein endothelial cells (HUVECs) were plated on the preadsorbed surfaces. Under the preadsorbed condition of Fn in the presence of more than 100-hold BSA, HUVEC adhesion depended on terminal functional group of the SAM as follows: COOH > NH 2 > OH > CH3. HUVECs adhered on COOH and NH 2-SAM preadsorbed with BSA, whereas HUVECs did not adhere on these surfaces immobilized with BSA. These results suggest that exchange of preadsorbed BSA with cell-adhesive proteins in liquid phase, such as fibronectin and vitronectin, induced cell adhesion on these surfaces.
