Figures & data

Figure 1. Effect of 1 hour PRP pre-treatment at 1/100 and 1/1000 dilution on SaOS-2 chemokinesis. The migration assay was performed in Boyden Chamber in 16 hours. Results are expressed as means of percentage of cells migrated versus control.

Figure 6. Phenotype composition of SaOS-2 cells after a 1 hour PRP treatment. Fluorescence images of the 3 types of SaOS-2 cells (Type I, Type II, and Type III) counted in control and PRP treated (for 1 hour) coltures. The number of cells is the mean of 6 fields for each treatment. Images in fluorescence microscopy at 10× magnification.

Figure 7. Effect of different doses of anti-PDGF-PRP pre-treatment on SaOS-2 migration in presence or in absence (DMEM) of FBS 1% as chemotactic agent. Before migration, cells were exposed for 1 hour to PRP at 1/1000 dilution. The migration assay was performed in Boyden Chamber in 4 hours. Results are expressed as means of percentage of cells migrated versus control.
