PROBLEM: Question: Does leukocyte concentration and composition in platelet-rich plasma ( PRP ) influence the growth factor and protease concentrations?
Answer: These findings demonstrate that leukocytes strongly influence the quality of PRPs. Therefore, modifying the PRP preparation method according to the pathology is essential to achieve better clinical results with PRP therapy.

SOLUTION: yes
