Effect of Fluoride-Modified Titanium Surface on Early Adhesion of Irradiated Osteoblasts

Figure 2

SaOS-2 osteoblasts attached on titanium disks under fluorescence microscope. (A) SaOS-2 attached on Ti disk which are stained by DAPI. The number of cells on the whole disks is measured. (B) The Ti disk is divided into nine areas. Five yellow squares (a–e) are selected. (C) Cell area and fluorescence intensity of cells in five yellow squares were evaluated.
