Proliferation evaluation of DRG co-cultured with living nerve microtissues or PRP supernatant. A-B The DRG in Micro-T + PRP group exhibited longer regenerated axons compared with those other co-culture groups and control group (^*P < 0.05, ^**P < 0.01). C Schematic of co-culture of DRG with nerve microtissue or PRP supernatant. DRG Dorsal root ganglions, Micro-T microtissues, PRP platelet-rich plasma
