Figure 2.
Quantitative results of alkaline phosphatase (ALP) activity in MC3T3-E1 cells 7 d after calcification induction. ALP activity is expressed as Abs405/g protein (n = 3, ** p < 0.01, †† p < 0.01, ## p < 0.01): ** multiple group comparisons among nontreated (NT) media; †† multiple group comparisons among calcification (Cal) media; ## two-group comparison between NT and Cal media.
