ABSTRACT

Objective To study the cellular affinity of the inorganic active element bone scaffold materials. Methods The specific surface area, pore size distribution, porous ratio, permeability ratio of the inorganic active element bone scaffold materials were evaluated in vitro. Human marrow mesenchymal stem cells(MSCs) were cultured and identified by the flow cytometry, the third passage of the cells were used to culture with scaffold materials, to compare with the cells cultured with pure fetal calf serum as the control group. MTT assay was used to examine the effects of scaffold materials on MSCs viability, the growth of cells was observed by scanning electron microscope (SEM). Results The specific surface area of the inorganic active element bone scaffold materials was 210 m2/g, mean pore size was 6 nm, porous ratio was 90 %, and permeability ratio was34 %. MTT assay showed significant difference in the number of cells between the scaffold materials and the control group (P < 0.05 ) on the seventh day, MSCs co-cultured with scaffold materials exhibited good growth as observed under SEM. Conclusion The inorganic active element bone scaffold materials possess preferable cellular affinity, which could be an overall-developed and high potential scaffold material of bone tissue engineering.
