In vitro biocompatibility test of Mg-IHC. (A) Magnesium ion concentration released by Mg-IHC in vitro was detected after 3, 7, 14, 21, and 28 days. (B) Cell viability detected by CCK-8 kit on 1, 3, and 7 days, respectively. (C) Statistics of the percentage of dead cells. Compare with Ctrl. **P < 0.01; ***P < 0.001. (D) Live/dead staining for MC3T3-E1 cells. The white arrows indicate dead cells. (E) Cell actin cytoskeleton staining showing the morphology of MC3T3-E1 cells on different substrate, stained with FITC-phalloidin.
