L-PRP enhances PGE 2 production. Enzyme-linked immunosorbent assay results of PGE 2 production by tenocytes after 4 days in culture. L-PRP induced higher production of PGE 2 when compared with P-PRP. The PGE 2 measurements in the three groups (control, L-PRP, and P-PRP) were normalized to respective cell numbers. Asterisk indicates comparison between each treatment and the respective control (P < 0.05). Pound sign indicates comparison between L-PRP and P-PRP (P < 0.05). Note that, for each group, three independent values were obtained, and the results are expressed as mean ± standard deviation. A t test was used for statistical analysis. L-PRP leukocyte-platelet-rich plasma, PGE 2 prostaglandin E2, P-PRP pure-platelet-rich plasma
