Figure 8: SMCs proliferation behavior of LBL10 and LBL10@Ebs. Note: (A) The staining results of smooth muscle cells cultured on different samples for 1 and 3 days (D); (B) the cell viability assay. Data are expressed as the mean ± SD. **P < 0.01, ***P < 0.001. SMCs: Smooth muscle cells; SS: stainless steel; LBL: layer-by-layer; Ebs: ebselen; LBL10: polydopamine coating sample with 10 cycles of LBL; LBL10@Ebs: micelles embedded sample with 10 cycles of LBL and Ebs; LBL10@Ebs+Donor: LBL10@Ebs sample incubated with SMCs culture medium that contains nitric oxide donors; CCK-8: cell counting kit-8.
