A, B) The expression of integrin β1 and vinculin at the protein level on different samples. “Merge” represents the merged images of actin (red), protein (green), and nuclei (blue). C ∼ E) RT-PCR detection of integrin β1, integrin α2 and vinculin gene expression in BMSCs after incubating on different samples for 4 and 12 h. F) Proliferation activity of BMSCs cultured on different plates for 1, 4, and 7 days. G) Evaluation of BMSCs proliferation at 48 h by EdU staining. *p < 0.05, **p < 0.01 when compared with Ti-PIII; #p < 0.05, ##p < 0.01 when Ti-PIII/PDA@ZnO-EDN1 compared with Ti-PIII/PDA@ZnO.
