Figure 6

The result of alkaline phosphatase (ALP) activity assay from supernatant (A) and lysate (B). A: In the supernatant, there were significant differences among the four experimental groups (p = 0.0003). In the comparison between groups, the positive control group exhibited significantly lower ALP activity than the smooth and DED groups. B: In the lysate, ALP activity was lower in the DED group than in that in the positive control. (* p < 0.05). (ALP: alkaline phosphatase, DED: direct energy deposition).
