Platelet-rich plasma promotes peripheral nerve regeneration after sciatic nerve injury.

ABSTRACT: The effect of platelet-rich plasma on nerve regeneration remains controversial. In this study, we established a rabbit model of sciatic nerve small-gap defects with preserved epineurium and then filled the gaps with platelet-rich plasma. Twenty-eight rabbits were divided into the following groups (7 rabbits/group): model, low-concentration PRP (2.5-3.5-fold concentration of whole blood platelets), medium-concentration PRP (4.5-6.5-fold concentration of whole blood platelets), and high-concentration PRP (7.5-8.5-fold concentration of whole blood platelets). Electrophysiological and histomorphometrical assessments and proteomics analysis were used to evaluate regeneration of the sciatic nerve. Our results showed that platelet-rich plasma containing 4.5-6.5- and 7.5-8.5-fold concentrations of
