Figure 9.

Alkaline phosphatase (ALP) activity test results of cells, (A) ROS 17/1.8 and (B) MC3T3-E1, after cultivation with MHA1 and HA for 5, 7, 10, and 14 days.

Notes: The samples were divided into four test groups: HA and MHA with and without exterior magnetic fields, respectively. “+M” stands for cultivation under exterior magnetic fields. The mean values were calculated from the average results of three samples, the error bars represent ± standard deviation.

Abbreviations: ALP, alkaline phosphatase; MHA, magnetic nanoparticle hydroxyapatite scaffold; HA, hydroxyapatite scaffold.
