Abstract

BACKGROUND:

AZ31B magnesium alloy with surface flouridization is a new type of magnesium alloy developed by Institute of Metal Research, Chinese Academy of Sciences. Its biocompatibility is unclear.

OBJECTIVE:

To observe the cytocompatibility of magnesium alloys with surface fluoridation tested by human bone marrow mesenchymal cells (BMSCs).

METHODS:

Human BMSCs were identified and cultured. The AZ31B magnesium alloy was taken as control and the AZ31B magnesium alloy with surface fluoridation was experimental group. Human BMSCs were the test cells. Leaching liquor of the alloy in both groups was used for cell compatibility experiments in vitro in order to evaluate the biocompatibility of AZ31B magnesium alloy.

RESULTS AND CONCLUSION:

The cell survival rate of AZ31B magnesium alloys with surface fluoridation was significantly higher than AZ31B magnesium alloys without surface fluoridation. The toxicity of cells in the leaching liquor of AZ31B magnesium alloys with surface fluoridation was Grade 1 and was non-toxic to the basic cell growth. The biocompatibility of the AZ31B magnesium alloys with surface fluoridation is superior to the AZ31B magnesium alloys without surface fluoridation.
