The attached hBMSCs exhibit a better spreading appearance
on the anodized I
1
and I
2
specimens compared to the untreated I
0
specimen, which states a positive sign for the biocompatibility of
the anodized nano/submicron-scale TiO

network surfaces [112].
The cell proliferation of hBMSCs on the anodized I
1
and I
2
specimens
was signiicantly faster than the untreated I
0
specimen [112]. The
XPS investigations of the Yang
