Synergistic effects of Citicoline and bone marrow mesenchymal stem cells to improving regenerative
capacity of acellular nerve allograft

Acellular nerve graft is an alternative to autograft for the repair of short gaps associatedwith peripheral nerve injury. It provides
a suitable three-dimensional structure that supports and guides axonal regeneration. However, outcomes associated with the
use of acellular nerve grafting are often inferior to those achieved with autografts, particularly over long lesion gaps. Therefore,
this experimental study was conducted to evaluate the effects of citicoline on the efficacy of acellular nerve allografts seeded with
Bone Marrow Stem Cells (BMSCs) to bridge a 15 mm sciatic nerve gap. Seventy (70) rats were randomly allocated into seven
groups (n=10 per group), including the healthy control group, sham surgery group, autograft group, acellular nerve scaffold
(ANS) group, ANS+BMSCs group, ANS+BMSCs+100 mg/kg citicoline and ANS+BMSCs+200 mg/kg citicoline groups. The
two experimental groups were treated daily with citicoline at the doses of 100 or 200 mg/kg for two weeks. After implantation,
motor function was assessed and electrophysiological, histomorphometry and molecular tests were performed. Animals treated
with citicoline immediately after implantation showed significantly better regeneration and motor function outcome compared
with ANS group and ANS+BMSCs group. No significant difference was observed between the citicoline treatment (200 mg/kg)
group and the autograft group. These findings suggest that citicoline treatment resulted in improved regenerative properties of
cell-seeded nerve allografts, likely via increasing the viability and retention of transplanted BMSCs.
