Polyethylene glycol-fused allografts produce rapid behavioral recovery after ablation of sciatic nerve segments

Abstract: Restoration of neuronal functions by outgrowths regenerating at ~1mm/d from the proximal stumps of severed peripheral nerves takes many weeks or months, if it occurs at all, especially after ablation of nerve segments. Distal segments of severed axons typically degenerate in 1–3 days. The purpose of this study was to show that Wallerian degeneration could be prevented or retarded and lost behavioral function restored following ablation of 0.5 – 1 cm segments of rat sciatic nerves in host animals. This is achie… Show more

“…We regard CAPs as only a “yes/no” (binary) measure of PEG-fusion success because CAP amplitude and time course depend on so many variables, including electrode shape, construction and placement, and numbers of axons having different diameters and myelin wrappings (Ghergherehchi et al, 2016). CAPs were evoked to assess electrophysiological function and continuity (Lore et al, 1999; Riley et al, 2015). Stimulating and recording electrodes were placed ~1cm apart across the site of intended transection and a CAP was recorded to confirm that the sciatic was intact and electrically viable.…”

“…Having this barbed inward projection will consequently produce outer surface fenestrations that can also facilitate placement of stem cells [11].or regeneration promoting factors like Polyethylene Glycol (PEG) [2]. Platelet Rich Plasma (PRP) or Fibroblast Growth Factor (FGF) [11].…”

“…Current strategies for peripheral nerve repair rely on regeneration or proximal outgrowth aided by microsutures, nerve grafts, or manufactured conduits [2,3]. However, even after repair, it can take months for regenerating axons to reach denervated target tissues when injuries are proximally located [1,4].…”
