Figure 5.
Proliferation of osteoblast response to SPP (A) and SPP-Ca (B). MC3T3-E1 was treated with different concentrations (0.7, 7, and 70 μM) of SPP and SPP-Ca (70 μM) for 72h. Changes in the ALP activity of MC3T3-E1 treated with different concentrations of SPP and SPP-Ca (C). n = 5. Data are presented as means ± SEMs and analyzed by one-way ANOVA followed by Tukey's multiple comparison test. *p < 0.05, **p < 0.01, and ***p < 0.001 vs. vehicle. ##Indicated significant differences, p < 0.05.
