Fig. 4. The adhesion morphology observed via CLSM (a), the adhesion levels obtained via CCK-8 analysis (b), and the relative gene expression levels of αv and β3 obtained via q-PCR analysis (c) from the study of MSCs cultured on SAMs with pre-adsorbed OPN for 12 h. In (a), the green and blue fluorescence corresponds to F-actin and nuclei, respectively. The stars indicate significant difference (p < 0.05).
