Fusogen sealant restores spinal cord function and morphology after complete transection in porcine model
By
Michael Lebenstein-Gumovski ,
Summary
This study investigates the use of a fusogen sealant (polyethylene glycol-chitosan conjugate) to repair completely transected spinal cords in a pig model. Three experimental pigs treated with the sealant showed remarkable recovery, including return of sensation from day two and ability to stand and walk on all limbs by day 60, while two control pigs remained paralyzed. Microscopic analysis confirmed axons traversing the injury site in treated animals, whereas controls showed degenerative changes. The findings suggest the fusogen sealant has significant therapeutic potential for spinal cord injury repair.

· 5 pulledControl animals maintained lower paraplegia, anesthesia, and pelvic dysfunction throughout the experiment.
In contrast, the experimental group showed positive changes, including the return of sensation from day two.
By the end of the study, all animals in this group could assume an upright posture and ambulate on all limbs.
Microscopy revealed axons traversing the injury site in the experimental group, whereas control samples showed degenerative post-traumatic changes.
This study demonstrates that a fusogen sealant based on a polyethylene glycol-chitosan conjugate promotes significant morpho-functional recovery after complete spinal cord transection, supporting its therapeutic potential.
