Purpose: To explore the potential neurotrophic and tissue-protective factors in platelet-rich plasma (PRP) and evaluate the therapeutic applications of the cytokine identified from PRP in a cavernous nerve (CN) injury rat model.
 
Materials and Methods: Thirty-eight rats were divided into five groups: group 1 - sham group, group 2 - vehicle-only group, group 3 - 400 µL PRP, group 4 - 100 ng/kg CXCL1 group, group 5 - 30 ng CXCL5. Groups 2–4 were subjected to bilateral cavernous nerve crushing (BCNC) injury. Four weeks later, erectile function was assessed by CN electrostimulation, and the CNs as well as the penile tissue were collected for histological assay. The CNs as well as penile tissue were collected for histologic evaluation and mRNA expression.
 
Results: found that the PRP contained higher levels of CXCL1, CXCL5, and CCL2. CXCL1 and CXCL5 were expressed strongly and CXCR2 was expressed weakly in the surface of the neurons of the major pelvic ganglion. The intracavernous injection of PRP may promote the stable expression of CXCR2 and increase the expression of CXCL5 and CXCL1 in the major pelvic ganglion after BCNC, and enhance the ability of neurogenic recovery. We found that the intracavernous injection of CXCL5 promoted recovery from CN injury-induced erectile dysfunction by preventing smooth muscle atrophy.
 
Conclusions: PRP’s therapeutic efficacy on CN injury induced erectile dysfunction may be a synergistically action with other multiple biomolecules and partly mediated by action of cytokine CXCL5.
