Does Platelet-Rich Plasma Freeze-Thawing Influence Growth Factor Release and Their Effects on Chondrocytes and Synoviocytes?

Figure 2

Expression analysis of factors involved in joint physiopathology: messenger RNAs expression in synoviocytes grown in presence of 10% fresh or frozen PRP at 7 days. Data were expressed as n°mol mRNA ×100000 GAPDH. Hyaluronic acid production was evaluated in culture supernatants and protein production was normalized per number of cells. Boxes indicate the 25% and 75% percentiles, whiskers indicate the minimum to maximum values, and bars indicate the median.
