Based on our previous investigations, the goal of the present work was to examine the individual and synergistic effects of the two different cell types in sciatic nerve injury . We pursued to evaluate the effects of BMSCs and SCs co-transplantation on the functional recovery after sciatic nerve injury in rat. </font></font></font><b><font color="#221e1f" size="1"><font color="#221e1f" size="1"><p align="justify">Methods: </p></font></font><font color="#221e1f" face="Times New Roman,Times New Roman" size="1"><font color="#221e1f" face="Times New Roman,Times New Roman" size="1"><font color="#221e1f" face="Times New Roman,Times New Roman" size="1">In this experimental research, adult male Wistar rats (n=32, 250-300g) were used, BMSCs and SCs were cultured, and the SCs were confirmed with anti S100 antibody. Rats were randomly divided into 4 groups (n=8 in each group): 1- control group: silicon tube filled with fibrin gel without cells 2- BMSCs group: silicon tube filled with fibrin gel seeded with BMSCs 3- SCs group: silicon tube filled with fibrin gel seeded with SCs and 4- co-transplantation group: silicone tube filled with fibrin gel seeded with BMSCs </font></font></font><font color="#221e1f" face="Times New Roman,Times New Roman" size="1"><font color="#221e1f" face="Times New Roman,Times New Roman" size="1"><font color="#221e1f" face="Times New Roman,Times New Roman" size="1">and SCs. The left sciatic nerve was exposed, a 10 mm segment removed, and a silicone tube interposed into this nerve gap. BMSCs and SCs were transplanted separately or in combination into the gap. BMSCs were labeled with anti-BrdU and SCs were labeled with DiI. After 12 weeks electromyographic and functional assessments were performed and analyzed by one-way analysis of variance (ANOVA). </font></font></font><b><font color="#221e1f" size="1"><font color="#221e1f" size="1"><p align="justify">Results: </p></font></font><font color="#221e1f" face="Times New Roman,Times New Roman" size="1"><font color="#221e1f" face="Times New Roman,Times New Roman" size="1"><font color="#221e1f" face="Times New Roman,Times New Roman" size="1">Electromyographic and functional assessments showed a significant difference </font></font></font><font color="#221e1f" face="Times New Roman,Times New Roman" size="1"><font color="#221e1f" face="Times New Roman,Times New Roman" size="1"><font color="#221e1f" face="Times New Roman,Times New Roman" size="1">between the experimental groups and controls.

The electromyography evaluation showed a greater improvement after SCs transplantation than BMSCs or the co-transplantation of BMSCs and SCs. </font></font></font></b></b></b></b></p>
