Mean (±SD) HA concentrations (ng/mL) in culture media from experimental groups at 1 and 48 h. Different lower-case letters represent significant differences between experimental groups at each independent time point. Different capital letters represent significant differences for the same experimental group at different times. HA, hyaluronan; IL, interleukin; LPS, lipopolysaccharide; PLT, platelet; PDGF-BB, platelet-derived growth factor isoform BB; PPP/PPGS, platelet-poor plasma/platelet-poor gel supernatant; PRP/PRGS, platelet-rich plasma/platelet-rich gel supernatant; TGF-β1, transforming growth factor beta 1; WBC, white blood cell.
