Adhesion of OBA9 epithelial cells to PRP pre-incubated titanium surfaces.

Adhered OBA9 cells were counted by nuclear DNA staining with Hoechst 33342. Each data point represents mean ± SD of three independent cultures. Kinetic adhesion was determined in the titanium that was pre-incubated with PRP from one representative donor (a). The adhesion assay was triplicated at 60 minutes with PRP from different donors (b). ** indicates a significant difference than control at the corresponding time point and in the corresponding donors (**p < 0.01).
