[Effects of the micro-arc oxidized film on pure titanium surface on attachment and growth of BMSCs].

Purpose: To evaluate the biocompatibility of oxide film formed by micro-arc oxidation(MAO) on titanium surface by culturing bone marrow stromal cells(BMSCs) on its surface and observing the BMSCs's biological behavior of early adhesion, growth and alkaline phosphatase activity.

Methods: According to the surface treatments, the samples were classified into 4 groups: MAO group, abrator group, abrator and NaOH-treated group, and untreated titanium group. Attachment, growth and alkaline phosphatase (ALP) activity of BMSCs cultured on the titanium surface of each group were assessed at different time.
