Cultured on manage and DMP1 coated disks. All cells were spindle-shaped on both groups, and more cells had been noticed on day 21 for DMP1 surfaces in comparison with handle (Figure three). The MTS assay of cell mitochondrial activity indicated that cells plated on DMP1 coated and uncoated disks proliferated at the identical price at 3 and 24 h. No statistically considerable difference among coated and uncoated Ti disks (p-value 0.05) was observed. Nevertheless, at day 3, the imply absorbance worth for DMP1 coated Ti disk group showed substantially more than the non-coated disk group (p-value 0.001) (Figure 4).Figure 3.

DMP1 Promoted Cell Differentiation and Extracellular Matrix Formation ALP staining around the 21-day culture revealed drastically higher active enzyme regions between DMP1 coated and uncoated disks (Figure 5). In Figure 5A, the staining reaction was far more intense on DMP1 coated Ti disk (16.535 0.1 ) and was statistically drastically higher than the non-coated group (0.0025 0.0025 ) (p-value 0.001). von Kossa staining showed the cultured hMSCs at day 21 around the DMP1 coated Ti disks had statistically significantly larger calcium mineral deposits (23.261 0.1) than the culture around the non-coated Ti disks (1.71 0.1) (p-value 0.05) (Figure 5B).
