(a) Fluorescent staining of BMSCs directly cultured and indirectly cultured, blue indicated DAPI-stained nuclei, green indicated Alexa Fluor 488-stained F-actin; (b) Average density of BMSCs on the sample surface; (c) Average area of BMSCs on the sample surface; (d) The average aspect ratio of BMSCs on the surface of the sample; (e) The morphology of BMSCs was observed by SEM; (f) Cell viability test of CCK-8; (g) LDH test; (h) Silver ion concentration in culture medium; (i) pH of cell culture medium. Values are mean ± SD, n = 15P < 0.05.
