In vitro experiment (A) Degradation curve in vitro (B): SEM images of DCPD coated magnesium scaffold soaked in SBF for 105 days (C): EDS spectral result in yellow box of (B) (D) Electron microscopic images of DCPD-coated magnesium scaffolds at 3 and 7 days after cell inoculation (E): Alive and dead stain on MC3T3-E1 cells after cultured by DCPD-coated magnesium scaffold extract for 1 day and 3 days (F):24, 48, 72-h CCK-8 cell proliferation detection; CCK-8 cell proliferation test, MC3T3-E1 cells were cultured in scaffold extract 24/48/72 h after the comparison of OD values in the DCPD MG scaffold group (red), negative control group (green) and positive control group (black). It was slightly higher than the negative control at 24H and 48H, and the same at 72H.
