Local Xenotransplantation of Bone Marrow Derived Mast Cells (BMMCs) Improves Functional Recovery of Transected Sciatic Nerve in Cat: A Novel Approach in Cell Therapy
Journal Title: Bulletin of Emergency And Trauma - Year 2018, Vol 6, Issue 2
Abstract
Objective: To determine the effects of bone marrow derived mast cells (BMMCs) on functional recovery of transected sciatic nerve in animal model of cat. Method: A 20-mm sciatic nerve defect was bridged using a silicone nerve guide filled with BMMCs in BMMC group. In Sham-surgery group (SHAM), the sciatic nerve was only exposed and manipulated. In control group (SILOCONE) the gap was repaired with a silicone nerve guide and both ends were sealed using sterile Vaseline to avoid leakage and the nerve guide was filled with 100 μL of phosphate-buffered saline alone. In cell treated group ([SILOCONE/BMMC) the nerve guide was filled with 100 μL BMMCs (2× 106 cells/100 μL). The regenerated nerve fibers were studied, biomechanically, histologically and immunohiscochemically 6 months later. Results: Biomechanical studies confirmed faster recovery of regenerated axons in BMMCs transplanted animals compared to control group (p<0.05). Morphometric indices of the regenerated fibers showed that the number and diameter of the myelinated fibers were significantly higher in BMMCs transplanted animals than in control group (p<0.05). In immunohistochemistry, location of reactions to S-100 in BMMCs transplanted animals was clearly more positive than that in control group. Conclusion: BMMCs xenotransplantation could be considered as a readily accessible source of cells that could improve recovery of transected sciatic nerve.
