Effect of GRGDS 3 density, filler amphiphile, and anchor SAM on MC3T3-E1 adhesion. Percentage surface coverage by adherent MC3T3-E1 (%) as presented in brightfield micrographs (Figure S4) of MC3T3-E1 after culture for 5 h on (A) MBA SAMs or (B) MDSA SAMs modified with different mole fractions of GRGDS 3 in Filler 1 or 2, χGRGDS3 = 0–0.25. (C) Representative brightfield micrographs of MC3T3-E1 after culture for 5 h on MBA SAMs modified with χGRGDS3 = 0.25 (left) and after incubating in 100 μM GRGDS 4 for 2 h (right). (D) Specificity of GRGDS-integrin binding for cell adhesion determined by calculating the average projected cell area per cell in panel (C) (****p < 0.0001).
