Neurotrophins and semaphorins expression in AL periprosthetic tissues and OA synovial membrane. The mRNA levels of neurotrophins NGF and BDNF (a), and semaphorins SEMA3A, SEMA3C and SEMA3F (b) were assessed in OA synovial membrane and periprosthetic tissues from AL patients. Results are represented as mean ± SEM, for n = 8–9 per group. **p < 0.01, *p < 0.05.
