The influence of AuNPs-AL on osteogenic differentiation. A and B Calcium deposition by MC3T3-E1 cells cultured with AuNPs-AL and AuÅPs-AL, assessed by Alizarin Red staining. Quantitative data are presented as the mean ± SD (n = 3). C and D Western blot analysis showing nonphosphorylated β-catenin protein expression in BMSCs cultured with AuNPs-AL and AuÅPs-AL for 7 days. Quantitative data are presented as the mean ± SD (n = 3). ns = not significant; *P < 0.05
